The grasshoppers made their appearance on Dahomy early in the springJ1.
first on the vegetation along the sloughs, the edge of the timber, and on iu
banks. I was on this property about three weeks ago, and found that whfl I
were rapidly increasing in numbers they had done but little damage to tJlil
eating a little young cotton at the end of the rows along the ditch banks, a4ii
and there we saw where they had cut some of the stalks of corn at the en qri,0

rows, and they were about that time beginning to feed on the oats. My .mn.q
have been reporting from time to time of their increase, but not until ten
did they report that they were going away from the ditch banks and c ..p..
covering the fields. ....
1 have just returned from this property, and beg to give ydu my observati :"JR
cerning the damage done to the various crops, as follows: :
Cotton.-They have totally destroyed 300 acres. What I mean by totally 4

winter cultivation, spraying the egg beds and young .grasshopnq

were. in evidence the day following each application, but careful t:
ovation soon revealed the fact that only th6se hatching after the.i
sion had been applied survived, and those were killed by tiwi
spraying. While the emulsion spray was found expensive winiwi
pared with that of cultivation; yet in the face of such coanditLo
prevailed in the Mississippi Delta its effectiveness many times
weighed the expense. Applications of coal tar were not m:e 4
