The Gould Improved Power Sprayer 
applies tl\e power in a straight thrust, relieving Pump and gears of 
undue strain and wear. This method makes practical the carrying 
of higher pressure than has been considered possible heretofore. 
A serious trouble of orchardists who are using power sprayers is 
the inability of the rig to stand up under constant pressure, owing 
to lack of rigidity and inefficient method of driving the Pump. This 
outfit, when operating under a high pressure, shows an abundance 
of surplus power, yet works smoothly and with an ease that comes 
only from surplus strength and rigidity. This is not accomplished 
by excessive weight and bulk. It is obtained by the method of driving 
the Pump, powerful back gearing, and pump being rigidly attached 
to same base from which it is operated. The base is only 45" long. 
Products of the Deming Company 
I There is great demand for efficient and convenient kerosene 
sprayers. The element of accuracy enters largely into machines of 
this type. The Deming Company, (Salem, O.), are putting on the 
market two which are carefully tested and are accurate as to propor¬ 
tions of oil and water. No measuring is necessary, since this 
method of making kerosene emulsion does away with the trouble¬ 
some mixing and boiling required in the old formula. 
Oil is placed in the smaller tank and water in the larger. By 
adjusting the indicator on the dial on top of the oil tank, any des : red 
proportion of kerosene, from one to fifty per cent, may be obtained. 
This is then thoroughly united with the water by the operation 
pumping, both in the valves of the pump and in the nozzle, the mix¬ 
ture being discharged in a very fine mist. Spray Pumps fitted with 
kerosene attachment are listed on the next page. When used for 
spraying solutions such as Bordeaux mixture, the oil tank may be 
removed or the supply of kerosene shut off by turning the indicator 
to the zero point. 
The Auto-Spray is not an entirely new invention, but a new 
model has been made by the E. C. Brown Co. (Rochester, N. Y.). It 
has a pump so arranged that it may be operated at any time without 
9 1 
taking the reservoirffrom the shoulder and a constant high pressure 
may be maintained. This feature, we believe, is not to be found in 
any other compressed air sprayer. 
The new model has a pump cylinder which is carried at the side 
of the operator and connected with the reservoir by a rubber hose. 
This pump cylinder being entirely free from the reservoir, and owing 
to the position in which it is placed while being used, it is perfectly 
convenient for the operator to pump up air pressure whenever neces¬ 
sary without removing the machine from his shoulder, or to pump 
constantly if desired to maintain a very high pressure. 
The Auto-Spray, for this year, is fitted with a new automatic 
shutoff, which enables the operator to control the spray easily. It 
is operated by a lever, and hence is not tiresome, as is the case with 
the thumb operated nozzle devices, which having no lever cannot be 
used for constant work. This automatic shutoff has large direct 
ports, which do not restrict the flow and pressure, and will throw a 
fine, mistlike spray with great force. 
The spray is carried in such a position, and the pump is so 
attached to the operator that there is not the least inconvenience in 
filling, carrying, or in pumping up the air pressure. The automatic 
attachment is conveniently operated by the left hand, while the 
pump is easily operated by the right hand. 
The Protumna Gas Sprayer recently put on the market by the 
American Horticultural Distributing Co., is, we believe, one of the 
newest things in spraying appliances. This sprayer has a special 
little device which prevents the gas, entering the spraying tank, 
from shooting down into the liquid and carbonating it as all gas 
absorbed by the water is lost so far as power is concerned. This is 
an important feature. The results of many experiments by the 
company indicate that this little device on the Protumna means a 
considerable saving in the quantity of gas used. 
Another move recently made by this company is, we believe, of 
great importance to the fruit growers. After a great deal of 
experimenting and correspondence with other experimenters and 
practical orchard men this company is now putting on every package 
of their Target Brand Arsenate of Lead a label guaranteeing not less 
than 60 per cent, water free Arsenate of Lead. This standard for 
Arsenate of Lead seems from all points of view to be the most desir¬ 
able one for the fruit growers. 
The 40 per cent, moisture makes a paste with the proper con¬ 
sistency for rapid mixing with water. The 60 per cent, of Arsenate 
of Lead makes the standard 10 per cent, higher than has been
