outfit so far as spraying is concerned. As a matter 

 of fact, practically all of our spraying formulas have 

 been prepared in terms of 50 gallons (one barrel), 

 and all of the spray tanks of the power outfits are 

 usually made in multiples of this number. 



A good barrel outfit may be placed on end or on 

 the side at the will of the operator. The cylinder 

 should be at the bottom of the barrel and the air 

 chamber on the inside of the same. A mechanical 

 agitator should be attached to the handle of the 

 pump in such a way that it will automatically stir 

 the liquid with each stroke of the same. Two lines 

 of hose are usually carried, each of which should 

 be not less than 25 feet in length, except under 

 special conditions. In spraying melons, cucumbers 

 and similar plants, after the vines have well covered 

 the ground, a line of hose 50 or even 100 feet in 

 length may be advantageously used by employing 

 one or two persons to carry the hose above the 

 plants. Each hose should be fitted with a bamboo 

 extension rod from six to eight feet in length. Noz- 

 zles of two or three different types should be on 

 hand in order to meet the varying requirements 

 for a coarse or fine spray. Any of the disk type 

 of nozzles now commonly manufactured will give 

 excellent results. Such an outfit will usually cost 

 from $25 to $30. A cheaper outfit is much more 

 expensive in the end. If kept clean and well packed 

 the above outfit should last for years and be very 

 effective. Over large areas of potatoes, the power 

 sprayer will be very much more effective and 

 economical. This outfit is mounted on wheels, 

 geared in such a way as to develop its own power 

 by traction and usually spraying four rows at a time. 

 In the economic treatment of large fields of pota-
