vastating Locusts still present in immense numbers ; but very few vines 
had been completely defoliated by them, and the green grapes were 
almost untouched, although large patches of the green bark had been 
gnawed from the vines by the locusts. The foreman of this vineyard 
informed me that he had not used the bran and arsenic mixture for fear 
of injuring the sale of the table grapes; but it seems to me that there 
need be no fear on this account, since the sugar or molasses used in 
making this mixture causes the arsenic to adhere to the bran, the wholt 
forming a compact mass which is not easily blown about by the wind. 
I noticed that the oak and pine trees growing in the immediate vicinity 
of this vineyard had not been attacked to any great extent by the locusts, 
and in a piece of weeds adjoining this vineyard on the west I found 
very few adults and no young of the Devasting Locust. The weeds 
along the sides of the roads in this vineyard had been burned off when 
the young locusts were first noticed for the purpose of destroying those 
that had hatched out in such places, but during my visit to the vine- 
yard on the 3d of August I found several young of the Devasting Lo- 
cust on the grape vines growing next to the roads, indicating that the 
burning process had not been entirely effectual. 
In the more central portion of this vineyard, away from the roads, I 
did not find any of these young locusts, nor did I find in such places 
any other kind than the Devastating Locust. I was informed that 
these locusts came into the vineyard from all directions, while higher 
up in the air could occasionally be seen swarms of locusts, presumably 
of this same species, which were going westward. 
Among deciduous fruit trees, cherry trees appear to have suffered 
most from the attacks of the locusts, which had not only completely 
defoliated them but had also eaten out the dormant buds. Pear trees 
had also been completely defoliated, while apple, quince, apricot, prune, 
and plum trees had shared a similar fate, but the green pears, quinces, 
and prunes escaped uninjured. On the apricot trees large patches of 
green bark had been gnawed away by the locusts, and the twigs thus 
girdled nearly always died. Young peach trees had been defoliated 
by the locusts, but the leaves of the older trees appeared to be dis- 
tasteful to them, as it was very rare to see a peach tree over 6 feet 
high that had been completely stripped. On such trees it was no 
uncommon thing to find that every green peach had been eaten, noth- 
ing but the bare pits being left, these sometimes still clinging to the 
trees, but more often lying upon the ground beneath them. Orange 
and walnut trees and English Holly were completely defoliated; pine 
and cypress trees were slightly eaten. I saw several California palms 
( Washingtonia filifera) that had been considerably eaten by the locusts. 
Egyptian corn growing in the immediate vicinity of trees that had 
been defoliated by the locusts escaped untouched, and this was also the 
case with several mulberry trees, although it was reported that the 
locusts fed upon the fruit of this tree. Fig trees also were but little
