The shoulder strap should be about an inch and a half wide over the 

 shoulder and at either end should have short straps with spring snaps for 

 the rings shown on the ends of the box. The strap at one end of the shoulder 

 strap should provide for varying adjustments in length. In the back of a 

 wide belt, fasten a small spring snap to attach to the ring shown in the dia- 

 gram on the side next the top. This ring is on a small strap, attached at its 

 ends. When the box is on one's back and the snap on the belt is in the ring 

 on the back (side) of the collecting box, the latter is held securely in place 

 without at the same time interfering with one's movements. One may run 

 or stoop over at will without having the box come tumbling in his way. 



This leather box which stands 8^ inches high, ii inches long and 73^ 

 inches wide is now ready for its fittings. Have the tinner make a pan 4 

 inches deep which will just force down in it. Depending on how the harness 

 mak^r has made the leather box, this will vary a little but the pan will be 

 about 10^ X 734 inches and should fit tightly in the leather box. This 

 pan should have two partitions dividing it into three equal compartments as 

 shown in the diagram. Make another pan about seven inches square and 

 one inch deep divided by partitions as you wish. I have mine divided in 

 halves, and one-half with two cross partitions dividing it into one larger and 

 two smaller compartments. This pan must be made to slip easily in and out 

 of the leather box. 



Make a third pan also about seven inches square and deep enough to 

 just fill the leather box when placed on top of the shallow pan, that is about 

 three inches deep. A fourth pan is about the same size as one of the com- 

 partments in the first made pan. It will be about 4 inches deep and 7 inches 

 long by 3)^ inches wide. These four pans will just fill the leather box, the 

 one in the bottom being firmly wedged in, the others fitting loosely so they 

 can be readily removed. A piece of tin with turned edges, measuring about 

 yys X 10^ inches, will serve as a cover for the box. Over this the leather 

 flaps on the ends are turned and the leather lid brought down and strapped, 

 holding everything securely. 



In the three bottom compartments and in the other pan of the same size, 

 carry ordinary envelopes (3-)^ x 6^ inches) with their flaps removed, set on 

 edge. In these envelopes place your specimens with the wings folded back 

 and the abdomens straight. Several specimens, depending on size, may be 

 placed in the same envelope. The end specimens should have their heads 

 toward the ends of the envelope. In the envelopes in these four compart- 

 ments a large day's collecting can be carried home in perfect condition and 

 in admirable shape for future papering or pinning. Some other form of 

 collecting box may be used to suit the collector, but no better method I think 

 can be devised for carrying home specimens than to place them in envelopes 

 which are carried on edge. The time required to place them in the envelopes 

 is more than saved by the admirable condition of the specimens when one 

 comes to paper them. 



In the shallow pan in the leather box the writer carries a pair of small 

 pliers, fine tweezers for handling specimens, some vials of pins and alcohol, 

 string, lead pencils, memorandum book and a small box or two for exuviae. 

 In the larger square pan is carried the lunch, some insect bags, etc. On the
