the changes in the weather incidental to our climate, and that 
certainly would be of value enough of itself; it would be a 
very interesting and valuable addition to our annual reports. 
The reports of such observations should be required to be as 
brief as possible, so as not to occupy too much space. Such 
reports would certainly have the effect of affording us the 
opportunity to better judge what would be the probable result 
of the changes in the weather, and we could govern ourselves 
accordingly as to the conditions we should be compelled to 
meet. I will not be strenuous in regard to the matter. 
Mr, Moyer: I think the weather is pretty well covered by 
the weather bureau. 
SPRAYING AT THE UNIVERSITY FARM. 
R. S. MACKINTOSH, ST. ANTHONY PARK. 
During the past season considerable attention was given by the 
division of horticulture to spraying, both for killing destructive 
insects and for fungous diseases. Spraying is becoming a very im- 
portant factor in our work, and should be better understood and 
appreciated by fruit growers generally. If you read the agricul- 
tural press or bulletins fron: the Department of Agriculture or ex- 
periment stations, you will find in them in most cases something 
relating to spraying. Itis now an unquestioned fact that spraying 
when done at the right time and in the right way will not only in- 
crease the yield but also keep the trees and vines in a healthy con- 
dition. Spraying is now practiced not only on small fruits and field 
crops but, also, on fruit and shade trees. 
When we started out for the summer conflict, about the first that 
we had to consider was the apparatus to work with. The outfit con- 
sisted of acommon force pump attached toa barrel that was fast- 
ened on its side to a stone boat. The entire rig was made so that it 
could be either hauled on the ground, as is a stone boat, or put into 
a wagon and hauled from place to place. One or two hose with noz- 
zles were used,depending upon the kind of work. The outfit worked 
very satisfactorily, though some changes might be made which 
would make it more easily handled. The nozzle that was found to 
do the best work under all conditions was the Bordeaux, manufac- 
tured in Salem,Ohio. Asarule, this season plants were not troubled 
as much as usually with fungous diseases, due to the excessively 
dry weather; however, considerable spraying was done in anticipa- 
tion based upon previous experience. 
Nearly all of the strawberries were sprayed with the Bordeaux 
mixture on May twenty-third. It appeared afterwards that there was 
very little leaf blight upon them, consequently, it would have been 
as well if the spraying had not been done; butitis far better to be 
on the safe side. 
The raspberries were sprayed with the Bordeaux mixture to pre- 
vent the anthracnose, which had done some injury to the canes the
