were required to operate the outfit, one to drive and pump and 

 the two others to manage the nozzles. An idea of the general style 

 of the outfit may be obtained from Plates Xm and XIV. 



The outfits used at the different places differed only in the 

 character of the cart. The pump, barrel and fittings were the 

 same in each case and cost $27.46. The items are as follows: 



1 "Eclipse " spray pump7 $10 00 



40 ft. " Maltese Cross " hose 10 00 



2 stop-cocks 1 50 



Freightage on spray pump 65 



4 nozzles 2 40 



1 barrel 65 



4.5 ft. brass tubing : 56 



3 strap-irons and bolts 45 



Lumber 50 



Labor 75 



Total $27 46 



The pump was fastened into the barrel by means of a detacha- 

 ble head 8 which was secured to the barrel by three strap-bolts. 

 This method of attaching the pump has been found not only more 

 convenient but stronger than simply fastening it to the head 

 which comes with the barrel. 



The hose used was what is known to the trade as " Maltese 

 Cross," warranted not to rot and to stand a pressure of 600 

 pounds of steam to the square inch. A three foot one-fourth inch 

 brass tube, furnished with a stop cock and bent at one end was 

 used to connect the same with the nozzles. 



At the end of each lead of hose a single nozzle was used in the 

 first two sprayings, but when the vines covered the ground two 

 nozzles were used. The two nozzles were attached to the three 

 foot brass tube by means of a short brass T. The bend in the 

 three foot tube was made at an angle of from 35 to 40 degrees. 

 Each arm of the T was about nine inches long and bent at about 

 the same angle as the main tube, the object being to bring the
