688 Report oF THE HoRTICULTURIST OF THE 
ing fungicides and insecticides in recent years. The knapsacks, 
force pumps and power spraying machines, with their nozzles that 
throw a mist-like spray, form a striking contrast to the brush 
broom and sprinkling pot of a few years ago. Still further 
improvements are looked for in the near future, particularly in the 
way of power machines for truck crops; especially for plants of 
a low spreading habit, such as potatoes and tomatoes, a device is 
needed that will pick up the prostrate vines, so that nozzles lowered 
near to the ground and directed upward will throw the spray up 
through the vines; in this manner it is thought that the spray 
will reach every part of the plant, which it can not do with the 
present appliances when the plants are large. 
for poisoning worms that feed on cabbage no liquid has as yet 
been found that gives satisfaction. The surface of cabbage leaves 
is such that the spray will not stick to them, but collects in drops 
and falls to the ground. The old-fashioned method of applying 
Paris green mixed with flour or plaster, with hand sifters, when 
well done is very effective. Whether any of the machines used 
for this purpose will do the same work as thoroughly and as 
cheaply is as yet a question. 
For small areas of vegetables and small fruits, for small vine- 
yards, and for vineyards located on hillsides where power 
machines can not be used, the knapsack sprayer is indispensable ; 
for larger fields, vineyards and orchards a hand force pump 
mounted on a barrel and fitted with the necessary hose and 
nozzles, answers the purpose admirably; but for the extensive 
grower of potatoes and truck crops and for the larger vineyards 
some form of a power sprayer is more economical. | 
In making a selection of a power sprayer one must be governed 
by the kind and extent of the crops to be sprayed and the kind of — 
land on which they are grown. A machine that will do good . 
work on level land might be useless on hilly land. In some 
localities the ground remains wet for a number of days aftera 
rain so that it would be impossible to use a heavy machine at a 
time when aspraying might be most needed. Then, again, in large 
fields of a light sandy nature the work would probably be too 
hard for one horse to perform. Each person must decide for him- 
self what machine is best adapted to his needs. 
In treating of the various machines for spraying truck crops, 
only those will be mentioned that have been tried by this Station; — ¢
