Glossy Writing Ink.—Any common writing ink can be made glossy by adding to it a little gum arabic or white sugar. If the latter is used care must be had not to use too much, else the mixture will be sticky when dry, and if too much of either gum or sugar is used the ink will become too thick to flow well.

Green Varnish for Metals.—For a green transparent varnish for metals, grind a small quantity of chinese blue with double the quantity of finely-powdered chromate of potash (it requires the most elaborate grinding); add a sufficient quantity of copal varnish thinned with turpentine. The tone may be altered by adding more or less of one or the other ingredients.

Hints to Draughtsmen.—A practical draughtsman in Wood and Iron gives the following simple suggestions, which will likely prove useful to some reader:—(1) In mixing up inks, the process is very much expedited by heating the dish and water in which it is mixed before commencing. It often happens in the summer that the flies walk over a tracing and eat off the ink in a very provoking manner. The use of vinegar instead of water will prevent this. In making a tracing, the cloth will take the ink much better if it is rubbed over with chalk. (2) Tracing-cloth that has been rolled up may be straightened out effectually and expeditiously by drawing it over the edge of a table or drawing-board, holding it down meantime with an ordinary three-cornered scale. (3) When there are a large number of drawings made and kept, a great deal of trouble and confusion can be avoided by making all the drawings on extra standard sizes. If a size of 16 by 24 inches be adopted, then the next larger size would be equal to two of these, or 24 by 32 inches. This enlarging or reducing process may be carried as far as the circumstances require, but it is always best to do it by the doubling or halving process if possible. One of the advantages of standard sizes of drawings is that they may be kept in a case of drawers, the size of which is made to accommodate the standard sizes selected.
