cornstalk was split lengthwise, a small hollow large enough to reeeiVe 
the larvae made in one piece and the two bound together with rubber/ 
bands. In this way the larvae could be observed as often as necessary 
without undue disturbance, as the larvae could usually be found in the 
central cavity which had been prepared for them. 
Part of the larvae have been reared in an out-of-door in,sectary (Fig. 
25), and part have been reared in the laboratory (Fig. 28).

We have also reared larvae in jelly glasses and in tin boxes, but of 
these two methods the tin boxes gave uniformly the better results and 
were much easier to handle. For this purpose we have used lately 
the Meyer’s patent box, four-ounce size, which is provided with a per¬ 
manent label on the lid (Fig. 27). This label was very convenient for 
making any records regarding the larvae contained in the box, such as 
time and date of last observation, when last provided with food, date 
.and time of molting, etc. Such records as were worthy of being 
permanently filed were put on sheets and filed in a vertical file. In 
this way there was no danger of confusing the record of one larva with 
another, and the complete record was always before the observer while 
•examining any individual.
