24 THE JOLA OR DECCAN GRASSHOPPER 
numbers on grass right down to the water’s edge. On 
the southern bank, on the other hand, for the first mile 
and a half, not more than half a dozen grasshoppers could 
be found, and it was only in one place, and this near where 
a, cart-track crossed the stream, that they could be found 
in greater abundance. This stream was, at the time of 
examination (7th, December 1910), not more than nine 
feet wide, and yet 1t had formed a quite effectual check to 
the grasshoppers. They are, however, very slowly gaining 
a foothold on the southern side of the stream and in the 
course of two or three years it will probably be as badly 
infested as the land on the northern side. 
Larger streams or rivers would, undoubtedly, form a 
practically impassable barrier to the spread of the oTass- 
hopper, were it not for the traftic by means of ferries and 
bridges that is continually going on between the two sides. 
Thus at Honnali the land in the village of Devanayakana- 
halli, on the southern side of the Tungabhadra, is 
badly infested while, on the opposite side in the neigh- 
bourhood of the ferry landing, the pest has made its 
appearance in small numbers. It is, of course, impossible 
to stop the traftic, but an attempt should be made to rouse 
the raiyats and cartmen who, by the way, for the most 
part have lands themselves, 0 the importance of seeing 
that their carts do not carry any of these grasshoppers 
where they move from an infested area to one not yet in- 
fested. The difficulty is, of course, to create any semblance 
of public spirit, the ordinary raiyat saying, “If my crops 
are attacked, I fail to see why I should endeavour to pre- 
vent the spread of the pest on to the land of others.” 
EFFECT OF WEATHER UPON THE GRASSHOPPER 
AND UPON THE EGGS. 
From observations made during the last two years, 
it appears that this grasshopper is not at all sensitive to 
changes of weather. The summer of 1910 was abnormally 
wet and yet the pest was more serious than it had ever 
been before. There was no sign of any disease, fungus or 
otherwise, among the hoppers, something which common y 
occurs among insects during abnormally wet seasons. 
The egg-masses also do not. appear to be sensitive to
