swelling and a smarting sensation similar to that occasioned by Poison 
Ivy, and which usually soon heals, but in some instances is said to break 
out again and cause considerable soreness. 
HOP LICE IN NEW YORK STATE. 
During the early part of June hop lice were very prevalent in some 
portions of Otsego County, N. Y., and a repetition of the damage of 
1886 was for some time anticipated, but, as has so frequently happened, 
the natural enemies of the insect appeared in almost equal abundance, 
and by the first of July the danger was past. This was a more or less 
local appearance, since in Oneida County no lice were noticed. In 
England, on the contrary, considerable damage has already been done 
by the lice and more is anticipated, as we notice from the Kentish 
Observer of recent date. 
THE GYPSY MOTH IN CAMBRIDGE. 
The home of the father of North American economic entomology has 
been invaded by the destructive Gypsy Moth, which, in spite of the 
assurances of the Commission, seems to have been spreading in the State 
of Massachusetts. Eecent examinations show the insect to have become 
widely distributed through the town of Cambridge, and many hiding- 
places hitherto overlooked have been found. Large colonies had sought 
the shelter of the sanctuary of the church and a number of nests were 
found under the steps of St. James Episcopal Church, on North avenue. 
The inspectors have been energetic and doubtless have prevented a 
serious plague, but they seem by no means to have succeed in eradi- 
cating the pest. 
An interesting feature of the work of the past season has been a 
children's crusade, instituted at Hingham by the Agricultural and 
Horticultural Society. It is reported that seventy-five children were 
engaged in the work and they collected a total of 68,006 egg masses, 
representing at least fifteen millions of caterpillars. Prizes were 
awarded to the five who collected the greatest number. 
A HOME-MADE SPRAYER. 
We notice an interesting article in a recent issue of the Kansas Farmer 
describing at some length how a farmer can make an effective sprayer for 
himself which will be sufficiently powerful and capacious to spray a 
large orchard, while the total cost to make it, including the pump, will 
be only $13. The apparatus is very similar to the one which we have 
several times described in our reports, and which is figured upon Plate i 
of Bulletin 6 of this Division. It consists simply of a kerosene barrel 
mounted upon skids, with a strong force pump inserted above. Two 
or three points of importance were brought out in our description which 
have not been touched upon by the Kansas Farmer article, but the latter
