Agitators.—In applying either Bordeaux mixture or Paris 
green it is very necessary that the liquid be thoroughly stirred 
in order to insure uniform strength in the application, otherwise © 
the copper compounds and the Paris green will settle to the 
bottom of the tank. Experience has shown that agitating by 
means of a hose returning a stream to the bottom of the tank is 
unsatisfactory. A wooden dash or paddle may be usually fitted 
to the pump so that with every stroke of the pump it will stir 
the mixture. When necessary, as for instance, after the tank 
has been standing still for a few minutes, this agitator may be ~ 
supplemented by stirring the mixture thoroughly with a stick. 
Except with geared pumps the above method is the most satis- . 
factory one that we know of at present. 
Bordeaux mixture not a cure.—The fact that Bordeaux mix- 
ture, or any other fungicide, is not a cure for fungous attacks 
can not be too strongly emphasized. The Bordeaux mixture is 
sprayed on the foliage and fruit simply to prevent the germina- 
tion there of the spores of the fungus by means of which the 
fungus is propagated. It is evident, therefore, that the Bordeaux 
mixture must be used as a preventive of, rather than as a cure for 
fungous attacks. For this reason the foliage and fruit should be 
kept covered with the Bordeaux mixture from the time when they 
first emerge from the bud till a month, at least, after the blossoms 
fall. The success of the treatment depends in a large measure on 
the timely and thorough application of the mrxture. 
Results of the experiments.— The results of these experi- 
ments certainly give an aflirmative answer to the question 
whether or not dilute Bordeaux mixture, containing one pound 
of copper sulphate to about eleven gallons of the mixture may 
be used successfully against pear scab and show, at least under 
the conditions existing in this case, that it may safely be relied 
on if it is applied thoroughly and at the proper time. This con- 
clusion confirms in a measure the results previously obtained by 
Galloway and Fairchild * and by Greene.t 
Spraying early.—So far as this trial is concerned the results 
shown in Table XX, p. 698, answer the question whether or not
