Ethnology of Manihiki and Rakahanga
Original House Type
Original House Type
The framework of the original type of house is composed of paired opposite side posts supporting two longitudinal beams, which in turn support a number of crossbeams. The crossbeams support the wall plates on their ends. The principal rafters rest on the wall plates, and their crossed upper ends support the ridgepole without the assistance of king-posts. The architectural principle followed resembles that of the Samoan long house, except that the Samoans use king-posts to support the ridgepole and cross the principal rafters above the ridgepole instead of below it (28, p. 20). The ground foundation upon which the Rakahangan house is erected is termed tango.
The framework technique, described from the surviving original type house in Rakahanga, is as follows:
Skeletal framework (figs. 4-6). The longitudinal beams, crossbeams, and wall plates are lashed together on the ground before the supporting posts.are erected (fig. 4). During the lashing each beam is supported by two short temporary posts slightly hollowed on the upper end to keep the round beams from rolling off. The temporary posts serve to raise the beams sufficiently high to allow the lashing patterns to be developed on the under surface. The two longitudinal beams and the crossbeams are of hala (Pandanus) trunks in the round. Nine crossbeams are used; of these, two are lashed close to the ends of the longitudinal beams and the remaining seven are evenly spaced to fill up the intervening space. Each crossbeam is securely lashed to each longitudinal beam with sennit braid. The somewhat thin wall plates are made of split hala wood. The two wall plates are laid over the ends of the crossbeams and lashed to each crossbeam with sennit braid. Three-ply braid (kaha) of a thicker size than that used on other parts of the framework is used for the beam and wall plate lashings (fig. 5). The turns of the braid are arranged to form decorative patterns on page 71 the under surface of the longitudinal and cross beams. The pattern is formed by alternating curves; the common lozenge pattern of other areas is not used. The term for the curved turns is ua, and the phrase used for tightening up such turns is uahia kia whakaketa.
Four supporting posts (pou) (fig. 6) made of coconut trunks are spaced on the house site in the same manner as the temporary supporting posts, so as to coincide with the lashed frame of beams and wall plates, and arranged in two side pairs, the distance between the posts of one side being 19 feet and between opposite sides, 12.5 feet. The posts when fixed in the ground are 6 feet high. The upper ends are notched to take the longitudinal beams, which are thus kept in position without any subsequent lashing. In extra long houses, two posts instead of one are used at either end of the longitudinal beam, and the longitudinal beam (fig. 6) is formed of coconut trunk instead of hala wood. When the posts are in position the whole beam frame (fig. 4) is lifted and the longitudinal beams are fitted into the notches of the posts.

House framework: a, view from above; b, side view. 1, temporary posts; 2, longitudinal beams (hapai), 24 feet 3 inches long, 7 inches in diameter, laid parallel 12.5 feet apart; 3, crossbeams (vae), 17 feet 4 inches long, 5 inches in diameter, ends project 2 feet 5 inches on each side beyond longitudinal beams; 4, wall plates (kaupapa), 25 feet 2 inches long, 4 inches wide, and 1 inch thick; 5, lashing of crossbeams to longitudinal beams; 6, lashing of wall plate to crossbeams.
Roof framework (figs. 7, 8). A scaffolding (turanga, standing place) is erected to facilitate the erection of the roof framework. This scaffolding takes the form of a roof framework with two end uprights supporting a beam in the manner of a ridgepole. Poles resembling rafters are placed in a slanting position from the ground to the ridgepole on either side, and lashed. Horizontal poles are lashed like purlins to page 72 the supporting rafters to form steps. The height of the end uprights and the slant of the side poles are adjusted so that the carpenters standing on the scaffolding can reach any part of the house roof from within. The method is widespread and has been described in detail for Samoa (28, p. 24).

End framework (fig. 9). The framework which closes in the ends (tara) of the house is composed of horizontal purlins and vertical rods which supply the thatch rafters, to which the thatching is attached. Wooden chocks (pono) are used to push out the lower end of the framework. Four horizontal purlins are stretched across the space between the end pair of rafters with the ends resting on the ends of the side purlins, to which they are lashed. The lowest purlin in the actual house is level with the end crossbeam, but in figure 9, a, it is a little too high. A mesial, rather thick rod is attached above to the crossing of the end rafters and lashed to the outer side of the four purlins. Its lower end projects a short distance below the lowest purlin. Two other vertical thin rods of thatch rafter material and size are spaced on the left and four others on the right. These lie outside of the four purlins and are lashed to them at the crossings. Above, they meet the end rafters, to which they are lashed. Below, they project slightly beyond the upper level of the lowest side purlins. Two additional purlins are next attached to the vertical rods on either side of the mesial rod, and their outer ends to the end rafters. The lowest purlins are on the upper level of the lowest side purlins. The cutting short of the mesial vertical rod leaves a space for the end entrance. The purlins are pliable, and chocks (pono) are placed between the end crossbeam and the fourth purlin to push the framework out a little from the perpendicular (fig. 9, b). The chocks, pieces of hala wood 4 inches by 2 inches, are three in number. The longest chock (fig. 9, b, 13) is 11 inches long and is placed immediately behind the mesial rod. Two others, 9 inches long, are placed also between the end crossbeam and fourth end purlin but directly behind the vertical rods on either side of the mesial rod. The fourth purlin gives a little extra length, and any adjustment of the lashing at the ends can be dealt with after the chocks are placed in position. Thus the lower end of the framework is not only pushed out slightly from the vertical, but by means of the graduated chocks the fourth end purlin has a slight outward, convex curve.
Dimensions of completed framework: total length in middle line, 26 feet 2 inches; width between eaves rods, 23 feet 11 inches; height from floor to main ridgepole, 16 feet 5 inches; height from crossbeams to main ridgepole, 10 feet; height of eaves rods from ground, 3 feet.

The roof and ends were thatched with sheets of lauhala (rau whara; Pandanus leaves) in which the leaves were bent over strips of aërial hala rootlets. The rootlets (kawhara, not kai whara, or rootlets with lower ends still in the air) which had reached the ground were used. The prepared strips (kaho, pronounced “kaheo”) measured 4 finger spans (anga honu, finger span), or about 3 feet.

Bishop Museum, C. 2811) slightly blunter than other; b, side view, upper surface slightly concave longitudinally; c, cross-sections with upper surface to right, upper surface slightly flatter than other, side edges rounded off. Total length, 10 inches; middle width, 0.9 inch; middle thickness, 0.4 inch; section about halfway between middle and points, 0.8 inch wide and 0.3 inch thick.
A roof sheet needle (tuiau) made of ngangie wood was used to sew the leaves together over the kaho strip. (See fig. 10; pl. 1.) The needle was exactly similar in shape to that of Tongareva. The butt ends of the lauhala were doubled over the kaho strip in the same way as in Tongareva and the Cook Islands (27, p. 15). When the leaves were pierced transversely with the needle, dry coconut leaf midribs (tunikau) or thin strips of aerial hala rootlets were passed through the holes made and kept the leaves together. The sheet was made the full width of the kaho strip (3 feet) and when completed was also termed a kaho. The full supply of sheets was made and the thatching (ato) commenced. The technique is as follows:
Thatching (ato) commences from below and works upward. The first sheet of lauhala is laid across the thatch rafters just above the eaves rod at one end of the tua frame. The part doubled over the hala rod is toward the top, and the doubled-over butt ends of the leaves are outside. The end of a piece of sennit braid is tied to the thatch rafter with a running noose. The braid is carried over the edge of the sheet to the right of the rafter. A hole is punctured through the sheet below the contained rod and to the left of the rafter. The braid is passed back through the hole from the outside and makes either a half-hitch or an overhand knot with its standing part and so fixes the stiff upper edge of the sheet to the thatch rafter. Subsequent sheets are added a little higher up the rafter than the one preceding, and a similar fastening is made with the continuous braid. The method is exactly similar to that used in the page 77 Cook Islands (27, pp. 20–23). For piercing the holes through the sheets, the fingers are generally used, but it was said that a hooked thatching needle was sometimes used. (See pl. 1.) No local name could be remembered for the implement, and as the people boasted that their method of piercing holes with the fingers was much quicker than the Rarotongan method with the needle, it is probable that the thatching needle was introduced from that area but never became popular. A Rakahangan thatching needle made of ngangie wood is shown in figure 11. It resembles the roof thatch needle in its width, which exceeds that of similar implements from the Cook Islands (27, p. 19).

Thatching needle: a, upper surface view; b, side view. 1, notch point, used for puncturing thatch sheet; 2, notch, hooks up braid and draws it back through sheet; 3, upper surface, concave longitudinally and fairly flat transversely; 4, unnotched point, may be used in sewing sheet together; 5, lower surface, convex transversely, side edges rounded off. Length, 11 inches; mesial width, 1.2 inches; mesial thickness, 0.4 inch; notch point, 1.2 inches long; base of notch point, 0.7 inch wide and 0.4 inch thick; other point at same distance (1.2 inches) from end, only 0.2 inch thick; notch, 0.3 inch deep.
The thatcher works a width of one sheet until he reaches the ridgepole, when another strip of thatching is commenced with the adjacent edges of the new sheets slightly overlapping those already fixed. The completed upward width of one sheet is known as a marewa, and the length of the house is referred to in the number of marewa it takes to thatch one side of the roof. The thatcher works from the inside of the house, and as he works upward he ascends on the scaffolding within, which is allowed to remain until the thatching is completed. An assistant carries the roof sheets and places them in position from the outside. The thatcher within usually spaces the upper edge of the sheet from the one below by the number of fingerbreadths decided upon. The closer the sheets are together, the better the house, but close thatching takes more material in sheets and sennit and involves a corresponding increase in labor.
The assistant uses a lifting pole (tukutuku) made of whano wood (fig. 12) to place the sheets in position when the thatching rises beyond his reach. The point of the long pole is stuck into the outer surface of the sheet in the middle line just below the site of the transverse hala rod at the upper edge. The shoulder prevents the pole from going in too far. The assistant lifts up the sheet with the point and swings it into position above the last sheet tied. The thatcher within adjusts it accurately and then lashes it.
The roof ridging is attended to after both sides of the roof have been thatched. The lauhala sheets have been extended as high as the ridgepole. The first stage in the roof ridging consists of applying a double sheet of lauhala on either side with the upper edges meeting in an apex above the upper ridgepole. The two sheets of either side are then sewed together with two-ply twisted sennit cord. The two double sheets thus sewed together (uihau) extend from end to end of the ridge. The second stage consists of reversing two plaited coconut leaf mats (pora) (see p. 111) with the shiny upper surface of the leaflets on the outside. These are doubled over the uihau and kept in position by passing pointed wooden pins about 2 feet long through the mats from side to side, taking care that the pins pass through between the upper and main ridgepoles. The upper ridgepole prevents the pins from working upward and thus anchors the mats in position. The reason for reversing the two pora mats is that there may be one unsplit midrib edge on either side of the ridgepole to hold against the pins. The double mats are laid on with a slight overlap until the ridgepole is covered from end to end.
The ends of the house are also thatched with lauhala sheets, the sheets being tied to the vertical elements of the framework in the same way as in the roof thatching. Some adjustment is required in cutting some of the sheets to fit in with the changing width of the area covered. The ends of the lowest sheets on both the sides and the ends are cut off a little below the eaves rod in a straight line to form the eaves (turuturu). At the ends the eaves are 3 feet 2 inches above the ground, and on the sides, 3 feet.
A high platform (whata) was constructed in the old houses by laying longitudinal joists (tarawa), five on one side and four on the other to leave a space for an opening, over the crossbeams (vae), and then laying cross pieces or poles closely over the joists to form a floor (papa). (See fig. 13.)
Through the left side of the rectangular opening (ngutu whata, door of the platform) made in the middle of the floor by the use of shorter cross pieces on either side, the upper chamber formed by the platform was reached by means of a ladder (ara) placed in a slanting position. The ladder was formed of a stout piece of hala trunk with short cross pieces lashed on as steps. The upper story was also used as a dormitory and as a storage space, especially for the mature coconuts kept to form the takataka stage. In special houses set apart for the tribal gods, the bodies of dead chiefs were laid out on the high platform.

Interior arrangement of house: a, ground plan; b, detail of fence (apaapa). 1, inner sleeping division; 2, fence formed of uprights 2 feet to 2 feet 3 inches high, some of which are driven into ground to act as posts, and two horizontal rods lashed to uprights; 3, supporting posts; 4, openings in fence; 5, doorways of house.
The house platform (paepae) now seen in dwelling houses of the Raro-tongan type, is an innovation which accompanied the houses introduced by the missionary, Aporo, from Rarotonga. The old type of house was built on the flat ground without any raised platform. Curbstones, such as mark some of the Tongarevan houses, were not used.
The ground floor was usually divided by a low fence (apaapa) into an inner rectangular sleeping part and an outer part contiguous to the sides and used as a dining room. The site of the fence was guided by the position of the supporting posts of the roof. The fence had middle gaps opposite the house doorways in all four sides to give admittance to the inner sleeping part. (See fig. 14.)
Wall And Door Screens
Wall screens (pataro whani) of plaited coconut leaves were used to form side or end walls when required, there being no permanent walls as in the Rarotongan type of house. The eaves of the house were fairly low, so that the depth of one screen was enough to reach the ground. Above, the screens were tied to a convenient part of the framework and simply hung down. The wall so formed was termed haihai. For the technique of the screen, see page 111, and for their appearance when hung, see plate 1.
Doorways (ngutupa.) The structure of the end framework to provide for end entrances has been shown in figure 9. The middles of the sides were also used as entrances, but here one had to stoop below the eaves to enter. The doorways were closed with pataro whani mats identical in structure with the wall screens.
