Stamp Collecting.

This is a hobby which needs the keenest observation. Young stamp enthusiasts have often been the means of discovering forgeries and assisting postal officials.

A stamp collector finds it necessary to study the currency of nations; the different methods of printing and the many varieties of paper. Collectors learn much concerning different shades of colour, inks and dyes, and collectors also study postal history and postal methods as well as many other fascinating subjects.

Apart from all this, stamp collecting is interesting because most girls and boys want to collect things. Every boy's pockets are chock-full of odds and ends.
