I suppose, or collectors can make them themselves, which I 

 do, but I have more time than most folks, being confined to 

 the house. Well, after having the case, to mount the insect, 

 first relax thoroughly, then expand upside down on the ordi- 

 nary setting board, only made perfectly horizontal, in the usual 

 manner. When dry place them still upside down on a strip of 

 smooth cork, and after extracting the pin from the thorax, 

 used in setting, replace it with a piece cut from an o or 00 pin 

 % inch long dipped in mucilage, being careful not to let it pro- 

 ject clear through, and also to have it stand vertical in drying, 

 during which it is well to replace the glass weights used in ex- 

 panding over the wings. Now take a sheet of )/% inch fine quality 

 cork and cut cubes yi inch, thrust a setting needle through one 

 side, and with a very sharp knife slope off the corners diagonally, 

 making a cone shape with a hole through, into this hole press 

 the outher end of the short pin, now well dried ; first dipping 

 it in mucilage. Now place the specimen, still upside down, in 

 the bottom portion of the case, and with a strip of glass long 

 enough to reach across the sides, adjust the cork by sliding it 

 up and down on the pin until it will just touch the underside 

 of the glass, of course, if the pin touches the glass it must be 

 cut down before adjusting the cork, which if the pin was ver- 

 tical and the hole through the cork perpendicular with the sur- 

 face, it will now touch evenly, if not, must be trimmmed 

 with the knife until it does. This having been done to the 

 pair, place them as you wish them to appear, still ups'de down, 

 on any smoth and level surface, clean the inside of the bot- 

 tom glass thoroughly, touch a very small bit of the glue with a 

 setting needle to the bits of cork and invert the box, dropping it 

 eently down until the glue touches. If all has been done cor- 

 rectly it will rest evenly all around the edge and the specimen 

 will not be displaced ; if so, let it dry an hour, clean the cover 

 glass, " telescope" it on, label and put away and your mount 

 will have these advantages. 



ist. The conventional position $ and 9 side by side is re- 

 tained. 



2nd. The insect is held entirely by one pin in the thorax as 

 usual.
