HATCHING OF THE SEVENTEEN-YEAR CICADA.— With reference to the  — 
eggs and young of the Seventeen-year Cicada, your correspondent from 
Haverford College, Philadelphia, is not the only one who has failed to 
produce the young, by keeping branches containing eggs in their studios. 
I so failed in 1834 and 1851, and indeed I have never heard that any one

a full week, after the date above mentioned. I could breed no Cieadas 
from branches that were dead and on which the leaves were withered, —

the egg-skin before it is broken. — S. S. RATHVON, Lancaster. 





PREPARATION OF Brgp's Eees. — The season for sani eggs has - 
now commenced, and it may be of interest to those engaged in odlogy | to

p.487, Vol. II. Now, agg desire the egg blown with only one hole, 
and that on the side. This is the only way now adopted by our best col |
