Pinning and Arranging for the Cabinet. — Here we may also adopt such 

 methods as will materially lessen the number of objections that have so fre- 

 quently been urged against Orthoptera as suitable specimens for the average 

 student of entomology to occupy himself with. Having shown in the preceding 

 paragraphs that loss of color, form, the injury by museum pests, etc., can be 

 avoided by a little proper care in collecting and handling them, the most impor- 

 tant matter that now remains for us to do in 

 pinning and arranging the specimens for the 

 collection is the economizing of space and 

 preserving a neat appearance in the specimens 

 themselves. In doing this we must keep in 

 mind the characters that must be used in 

 studying and classifying the insects under 

 consideration. We must also aim to preserve 

 the antennae and legs intact. In the winged 

 forms a single specimen can be made to show 

 the insect with these appendages both spread 

 and folded. (See Fig. 4, b.) The antennre, 

 when long, should be directed backwards along 

 the sides of the body of the insect. In like manner, the legs can be so folded 

 and crossed as to take up the least possible amount of room and still be ac- 

 cessible for the student's use in studying the specimen, as is shown at c in 

 Fig. 4, a " walking-stick." A single specimen, in this manner, can be made to
