outfit. They desire a sprayer so arranged that all of the work is 

 done by horse power. Sprayers of this description are necessarily 

 somewhat complex and consequently expensive. Several different 

 kinds have been placed upon the market, but they have been so 

 defective in various ways that farmers have become suspicious of 

 this class of sprayers. The perfect power sprayer for potatoes 

 has not yet appeared. 



In the spring of 1896, the Riverhead Agricultural Works, 

 Riverhead, N. Y., put out a new Hudson Special Bordeaux 

 Sprayer. This machine having certain new, and, apparently, 

 desirable features, and being manufactured and sold by a firm 

 located in the potato growing section of Long Island, it seemed 

 necessary for us to test it so that we might be able to answer cor- 

 rectly the inquiries which are certain to arise concerning it. 



We used it throughout the season of 1896 foi- spraying about 

 seven acres of potatoes near Jamesport, Long Island, and found it 

 quite satisfactory. One of the strong points of the sprayer is the 

 manner in which the nozzles are arranged. There are two noz- 

 zles to each row, and they can be readily adjusted to suit the size 

 of the plants. We are thoroughly convinced that one nozzle per 

 row is entirely insufficient, except, perhaps, for the first spraying. 



We experienced very little diflSculty from clogging of the noz- 

 zles. The Bordeaux mixture is drawn from the bottom of the 

 barrel and this is generally considered an objectionable feature, 

 aince there is more liability of the nozzles clogging than there ii 

 when the escape tube leaves the barrel from ths top. But in the 

 Hudson sprayer the agitation of the liquid is so thorough that 

 this difiiculty is overcome, provided a reasonable amount of care 

 is used in straining the Bordeaux mixture and in rinsing out the 

 barrel. The ease with which the barrel can be filled is another 

 good feature of the machine. 



This sprayer should give excellent satisfaction, if in operating 

 it the following rules are heeded:
