 MATERIALS. 



There is little to be added in. regard to spraying aud spray materials 

 since the publication of Part IV. During the past season, many local 

 brands of ar senate of lead have been placed on the market, and excellent 

 results have been obtained, proving that this mixture can be produced 

 locally at a much lower cost than the imported article. Many of these 

 brands have been tested by the Department, and the particulars of the 

 analyses may be found in the Journal of the Department of Agriculture 

 for October and December, 1910. The formula recommended by the 

 Department has been largely in use, as it is easy to prepare, and the 

 cost is slight. 



THE " FRIEND POWER SPRAYER. 



During the last couple of years, many of the leading orchardists have 

 discarded the old-fashioned hand spray pumps, and have purchased 

 the up-to-date motor spray pumps, and, according to their statements, 

 excellent results have been obtained. Some of the principal benefits 

 to be derived from using the motor spray pump are that the spray 

 mixture will go further, will be more evenly distributed, and one man 

 can manage the outfit, whereas by the old method two or more men 

 were required to work the hand pumps^ and the mixtures were not 

 evenly distributed over the trees ; in addition, the wages of the two 

 men were an extra item charged against the upkeep expenses of the 

 orchard. These motor spray pumps are placed on carts or patent 

 trucks, and can be drawn over the rough ground without any trouble.
