vation. The sprayer must be one of the most iQjportant machines to 

 be used in orchards, vineyards and small fruit plantations that fruit- 

 growers can have, and is becoming as important a factor in fruit-grow- 

 ing as the plow, cultivator, hoe or knife. 



But many an improvement is yet to be made in our spraying 

 apparatus before we reach the desired end we wish for. All the 

 sprayers take too much work to pump them, and the force is too vari- 

 able to cause a steady spray at all times. 



For large orchards a power machine is needed ; but none of them 

 work to the satisfaction of the orchardist, and the same may be said 

 of the hand-sprayers. 



Mr. Wm. Byers, of the Olden Fruit Company, has put on an im- 

 provement that seems to me the most important one that has yet ap- 

 peared or been suggested by any person. It can be used with a power 

 pump or hand-pump on a wagon platform. 



He uses for the air-chamber of the pump the large hot-water 

 tanks that are used in the kitchen stoves to give hot water to the 

 house where water-works are established. He pumps the water direct 

 into the bottom of these tanks, and the large air-chamber of these 

 tanks creates a powerful pressure that will last for four or five min- 

 utes after the pump stops working. 



These tanks are about four feet high and a foot in diameter, and 

 made very strong, capable of sustaining a pressure of 300 lbs. Any 

 of the ordinary spray-pumps will give a pressure of 100 lbs. to 120 lbs. 

 and will susttiin that for some minutes after the pump stops working. 



The spray-pipe goes to very near the bottom of the tank and 

 passes out of the top, where two hose and nozzles are attached, giving 

 two good strong sprays. An extra hose runs to the barrel to keep the 

 liquid agitated. 



The same plan is used when the power pump is used. A sprocket 

 wheel is fastened on the hind wheel of the wagon and an endless chain 

 attached to a -rotary pump, and power enough is given so that when 

 the wagon stops the spray continues for some time. 



The cost of such a power pump and tank, all complete, need not 

 be more than 825 or $30, instead of $75 or $80, as do all the power 

 machines now in use. 



The World's Fair matters have all been settled up, and the Com- 

 mission have paid to the Society all moneys expended for the display 

 made there. Money had been advanced all along through the year by
