thoroughly worked out, thoroughly done for one season at one 
place, and is now done by the people themselves, who bear the 
whole expense and who subscribe the necessary funds. Wherever 
the Rice Grasshopper is a pest, it can be met by this method, and 
it is now solely a question of demonstrating the process year by 
year, as it is rendered necessary by destructive outbreaks of the 
pest, till all affected areas know of it and do it. 
BOLLWORM IN COTTON. — The cotton-plant in India is attacked 
by three species of Bollworm, two Harias and a Gelechia. In 1905, 
the cotton crop Over 700,000 acres of the Punjab was a failure. 
Investigation showed that Bollworm arias was enormously 
abundant, so much so that in many areas every flower bud was 
eaten before it opened, and the crop was reduced to one-eighth or 
a quarter of what it should have been. The loss to the growers was 
about £ 2,000,000. The measures resolved upon and carried out by 
the Punjab Agricultural Department were : 1) to destroy all the 
plants still standing in January, to prevent hibernation of the Insect 
in the resting larva or pupa stage; 2) to plant bhindi Zibiscus 
esculentus as a trap crop and destroy it before the cotton flower- 
ed; 3) to reestablish the parasite, believed to have been killed in 
the preceding winter by the abnormal cold, whose absence we 
believe led to the outbreak. The last is the most important, and we 
looked to it mainly. The first measure was done by putting press- 
ure on in every district and by the free use of leaflets, 80,000 of 
which were sent out. It was probably fairly well done over the 
greater part of the area. The second was a failure, because bhindi 
is a garden crop, requires frequent watering when young, and the 
bulk of the people did not understand it. In a few places where 
there were market gardening castes it was grown and was probably 
useful. The third was done by sending in boxes of bhindi pods 
containing Bollworms from places outside the Punjab, some coming 
over 1,000 miles. The box was so arranged that parasites could get 
out through wire-gauze of such a mesh to keep in the Moths. 
Whether from this cause or not, the parasite was reestablished in 
the next season and the Bollworm reduced to its normal level. The 
strongest reason for believing the parasite was the real cause, was 
shown by the neighbouring area of Sind, to which no parasites 
were sent and in which Bollworm raged unchecked the next year; 
in the following year, the parasite was sent to Sind, and the Boll- 
worm in that season became normal. An account of the Punjab
