2. Avery young hopper will average, in traveling on hard soil, 
about one foot every five minutes. They make about one foot at 
a jump, rest awhile and jump again. On soft soil their rate of 
travel is very much less than on hard—only a very few inches every 
five minutes.

3. The accompanying drawings, made from living specimens 
by Miss Iris Wood, show the successive stages in the hatching of a 
grasshopper, and its freeing itself from the enveloping membrane, 
or so-called “amnion.” Fig. 1, breaking through the egg-shell; 
Fig. 2, a few minutes later; Fig. 3, still later; Fig. 4, freed from 
the egg-shell, but still wrapped in the “‘amnion’’; Fig. 5, kicking 
off the “amnion.” The length of time required in this process 
varied from about four minutes to fifteen, possibly dependent upon 
the amount of moisture present in the soil containing the eggs.
