height and depth of such a construction would depend upon the 

 number and the width of the boards or saddles that would be 

 put therein. The width would be that of the length of the 

 boards, which is usually 14 inches. About a quarter of an 

 inch of cork is cut off each end of the saddles, and grooves are 

 cut in the sides of the house for these to run in. The back and 

 the door should have a square of fine perforated zinc inserted 

 in them for ventilation. As an example of holding capacity it 

 may be well to note that a house with a height of 12 inches, 

 and a depth of 6 inches, 

 inside measurement, 

 would take eighteen 2- 

 inch boards if the 

 grooves were cut at 2 

 inches apart, or twenty- 

 four boards of same 

 width if It? inch only 

 were allowed between 

 the grooves. 



In taking insects off 

 the sets, the braces or 

 strips should be re- 

 moved from the wings, 

 and the pins from the 

 horns, with care, as a 

 good deal of damage can be done in the performance of this 

 operation, simple as it seems to be. A little twist of a brace 

 and away goes a patch of scales, a side slip of a pin and off 

 comes a horn. 



Pending the arrival of that twelve or twenty drawer cabinet, 

 the beginner will probably be content to arrange his specimens 

 in boxes. A handy sized box is one measuring 14 inches by 10 

 when closed, and it should have a cell for naphthaline.
