rrerenlive method. — The most effectual preventive method is to take 
ofl' the c^^«r'^ during: the winter months, as they are easily recoj^niized by 
their whitisli web cover at the branclics. \\)i' this purpose pruning* is 
indispensable, eggs being almost always on the tops of the branches, 
and when ])riincd they should b© immediately burned. The remaining 
branches should be carelully searched. The i'ii:^;^^ are always placed near 
the hibernating nest of the pear leaf-roller, Uhodophaa holUiiKlella l^ig. 
Kerosene emulsion is very beneticial after pruning as well as in early 
June, at the time of larva's hatching, for it kills at the same time the 
larva' of leaf-roller. After the larva* bore into the fruit no remedy is 
accessible excejit carbon bisulphide, but this chemical being very 
exi)ensive I oidy used it on a dwarf tree, i)ouring it with a small brush 
into the hole through which the insect entered. It very foou killed the 
insect and no injury was done to the fruit. Now, in our garden, i)ick- 
ing off the injured fruit by hand is the only means resorted to, as they 
are easily recognized by their black holes and their excrement. Lump 
sugar is of no use, but a sugar solution in Sukv in any glass vial attracts 
them.

T'nder commission dated July 27, 1897, and letter of instructions of 
the same date, 1 left Lincoln on the 3d of August, by the P)urlington 
Lailroad, for some of the western counties of Nebraska. The first stop 
was made at Benkleman, where I learned that much damage had been 
done in Dundy County in this and preceding years. From this point I 
proceeded to Denver, stopping at Haigler, Xebr., and at Yuma. Akron, 
and Fort Morgan, Colo., at each of which points collections were made 
and inquiries addressed to residents regarding locust deva.stations. 
From Denver I worked up and down the foothills of the mountains 
through the most productive agricultural part of the State, making 
sto})s at (jreelej'. Fort Collin.s, Longmont, Colorado Si)rings, ^Lmitou, 
Colorado City, and Pueblo. I i)roceeded from Pueblo to (irand Junc- 
tion, stopping at Canon City, Salida, (rlenwood Springs, and DePecpie 
between these places. Some interest attaches itself to investigations 
made in the Grand l^iver Valley, the rich fruit-growing region of the 
State, on account of the damage done in the spring of 1893 to fruit 
trees by locusts, and the i)robability of a recurrence of it. Stops were 
made at Salt Lake City, Ogden, and Cache Junction in Utah: and in 
Idaho, Pocatello, American Falls, and numerous other places along the
