used soda-bordeaux, hydrate-bordeaux, and potash- 
bordeaux. The spraying began June 2d, and ten spray- 
ings were applied during the season. The applications 
were made with a knapsack pump, and therefore were 
far more expensive than they would have been if the 
sprayings were made with horse-power. With the 
fungicide costing $5.00 per acre, and a machine that 
would spray two or more rows at a time, it would be 
possible to reduce the cost to $10.00 per acre, or even 
less. In effectiveness the soda-bordeaux stood first. 
Between the other fungicides there was but little dif- 
ference. ‘The best results showed a reduction of rust 
of about one-quarter, which is not as satisfactory a 
result as had been expected. 
In the spraying work condu¢ted by Professors G. 
E. Stone and R. E. Smith, at the Massachusetts Ex- 
periment Station, the results were more encouraging. 
The solutions used were potassium sulfid, saccharate 
of lime, and bordeaux mixture. The spraying was 
done with a knapsack sprayer, provided with a Ver- 
morel nozzle, and after the first application it became 
evident that the practice was of little importance on 
account of the difficulty in making the solution stick 
to the plant. For successful spraying of asparagus a 
finer nozzle is required than any that is now in the 
market. 
In some other experiments carried out on a small 
scale the asparagus plants were practically covered 
with solutions, when they were put on with an ordi- 
nary cylinder atomizer, and the lime solutions showed 
excellent sticking qualities; but with the ordinary 
coarse nozzle the solutions would run off of the glossy
