Insects and Other Foes. — lit 



drops, especially on the lower end of leaves, and evaporating, 

 leave the poison often too concentrated for the good of the 

 plants. We now avoid this danger by the application of the 

 liquid in the form of a mere mist with our modern sprayers and 

 modern spray nozzles, and by the addition of a little lime to the 

 Paris green water. 



A good knapsack sprayer (now to be had for about ten dol- 

 lars) fitted with a good, improved Vermorel spray nozzle, will 

 answer for spraying smaller patches, up to a limited number of 

 acres. For larger areas, and if it can be afforded even for an 

 acre or two, I greatly prefer the barrow sprayer here illustrated. 

 It is especially designed for spraying potatoes and similar crops, 

 and works to perfection. When the soil is rough or stony, and

 the strength of the operator at the handles, a horse or boy may

 and with little effort will pull the machine along. Two rows are 

 sprayed at a time, but if bugs are very plentiful, I would prefer 

 to go between every two rows, and thus spray every row twice, 

 in opposite directions, in order to make the job all the more 

 thorough and effective. An automatic agitator, which, like the 

 pump, is geared to the wheel, keeps the liquid in the tank con- 

 stantly stirred and prevents the Paris green from settling to the 

 bottom. 



Unfortunately, it must be said that the Paris green now on 

 sale in general grocery and hardware stores, although put up 

 and recommended for the very purpose of being used for the 

 potato beetle pest, is by no means of uniform strength, and 

 some of it decidedly weak. The proportions which we formerly 

 used with telling effect, namely, one pound of Paris green to
