The Pear Tree Psylla 
T HE pear tree psylla is a serious pest to the 
growers of pears. They are exceedingly 
small insects, almost microscopic, but upon being 
viewed through a magnifying glass resemble a 
cicada or harvest fly. They infest the foliage of 
the tree during the growing season and secrete a 
honey dew; and where there are large numbers, 
this honey dew makes the tree sticky, or may even 
fall in drops. The result of such attacks is to make 
the leaves drop and consequently the crop is 
injured or lost. 
Mr. H. E. Hodgkiss, of the New York Experi- 
ment Station, has found, after four years’ work, that 
it can be easily and effectively fought by spraying. 
The most effective spraying is made during the 
late fall or early winter to catch the adults (the 
fruit growers call them “flies”) which winter over 
under the rough bark. The first proceedure is to 
scrape the bark on a damp day, for the bark scales 
are more easily removed at that time. The bark 
scraped off should be gathered and burned, for if 
allowed to remain on the ground for a few days, 
the insects may escape to surrounding vegetation 
and hibernate there. Then spray, on a day so 
warm that the liquid will not freeze on the tree, 
with Black Leaf 40, using three quarters of a pint 
in one hundred gallons of water, to which three to 
five pounds of soap are added after being dissolved. 
Very effective work can also be done in the 
spring as the days begin to warm — late March or 
early April. Fish-oil soap may be used instead, 
dissolving one pound in five gallons of water. 
Trees which have not been so sprayed, but which 
are infested, can be effectually cleaned up for the 
season by deferring the dormant spray on the pear 
trees until the cluster bud is separating — the buds 
well apart but not showing much color. Use con- 
centrated lime-sulphur, diluting the commercial 
material one part to eight parts of water. This 
spraying will destroy the eggs about to hatch as 
well as the recently hatched larvae. There is no 
danger of doing serious damage to the pear buds 
at this time. They may be browned a bit and a 
few buds fall as a result of the pedicals being burned, 
but there will be no diminishing of the crop. 
Whether spraying is made at this time or when 
dormant, it must be very thorough; every square 
inch of bark must be covered and every crevice 
filled, if the work is to be effective. Clean cultiva- 
tion will also help to keep the trees clean as there 
will be no vegetation about the trees upon which 
the psylla can hibernate over winter.

Preservation of Hen Manure 
I WOULD like to make an addition to your 
answer to the query on the preservation of hen 
manure, on page 10 of the February issue. In the 
report of the Maine Agricultural Experiment 
Station, for 1903, an experiment to preserve hen 
manure is recorded. 
It was found that hen manure stored in a barrel 
from November to May lost one half its nitrogen 
content. It was found that the nitrogen could be 
retained or fixed by adding to the fresh hen manure 
a little more than one half its weight of either 
kainit or acid phosphate; that is, to each pound 
of hen manure, a little more than half a pound of 
one or the other of these materials. 
The cost of these materials is usually about the 
same. But in many instances I believe it would be 
better to reinforce the hen manure with acid 
phosphate, as many of our soils are more deficient 
in phosphate — the plant food in acid phosphate — 
than in potash. The only drawback in using 
either of these materials is the hen manure becomes 
rather wet and sticky. This can be overcome by ad- 
ding some absorbent, such as dry earth or saw dust. 
Dr. L. L. Van Slyke, in his book “Fertilizers and 
Crops,” makes an even better suggestion. “To 
each ten pounds of fresh hen manure, add four 
pounds of sawdust or dry muck, four pounds of 
acid phosphate and two pounds of kainit. This 
will result in a fertilizer that will contain in each 
ton ten pounds of actual nitrogen, 63 pounds of 
acid phosphate and 30 pounds of potash, a very 
good fertilizer for general use on farm or garden 
crops.”
