 drawer may slide easily. A similar box with a wooden 

 rabbet is used at the Museum of Comjoarative Zoology at

quires hooks on the sides to ke^ the cover down; it has 

 the advantage of greater cheapness, as it can be made of 

 soft wood, but is at the same time clumsier. My own 

 drawers are made of cherry sides, and have also a false 

 front attached to them, furnished with mouldings and 

 handles so as to present a not inelegant appearance; and, 

 exclusive of the cork with which they are lined, cost $2.65 

 each; they measure inside 18| inches long, 14 inches wide, 

 and 1| inches deep, not including the cork lining. 



It is best always to cover the bottom of such drawers 

 with cork or pith wood or similar soft substance, as it is 

 difficult both to insert and to withdraw the pins readily in 

 any ordinary wood, however soft; and the sides and bot- 

 tom should afterwards be covered with thin white paper 

 for neatness' sake.
