In a relief-map of any continent, lowlands and valleys may berepresented in green, mountains in brown, lakes in blue, anddeserts in buff. * Naples yellow is the conventional color forplateaus, but in most cases it will be better to represent bothhighlands and mountains in brown. Relief-maps should be molded upon boards specially preparedfor the purpose. For use in the class-room a very convenientform may be made by nailing strips on the ends of short lengthsof thin pine boards. The strips prevent warping. The molding-.

Sincethe map is intended to remain upon the board, the general ap-pearance of the work may be much improved by painting theboards Hght blue. The continent and its neighboring islands willthen stand out in strong relief. Instead of the thin boards hererecommended, squares and oblongs of book-board may be used ;but the putty will not adhere so readily, and the pieces are apt towarp. If a set of relief-maps of the continents be constructed, it willbe well to adopt some uniform scale, since better ideas of the rel-ative sizes can thus be obtained. With the boards 13 by 16, ascale of 400 miles to the inch may be employed. The followingdirections are such as may be found useful in loca
