POTATO SPRAYING EXPERIMENTS 1909. 

 PRODUCE OF TUBERS PER ACRE. 



It is noticeable that the simple device of cutting off the top of 

 the plants as soon as the disease appeared had the result of 

 considerably increasing the yield of sound tubers and of total 

 produce. How such an increase could have taken place in view 

 of the larger quantity of diseased tubers is hard to explain, and 

 it seems to open up interesting considerations. 



MONTAGU M. TAYLOR, GEO E. CHAMPION. Trials of Fruit Tree 

 Spraying Machines at Gloucester 1909. Journal of th* 

 R. Agric. Soc. of England, Vol. 70, 1909, pp. 193-195. 



These trials were held in the orchaids of Mr. Martin Chant at 

 Hucclecote, on June 17 and 18. Four power machines and twenty- 

 six hand machines were entered for competition. 



Among the first Messrs. Weeks and Son entered a 5 HP. oil 

 engine driving three-throw plunger pumps.. The engine and pumps 

 were mounted on a four wheeled frame. This machine supplied 

 the nozzles of eight lengths of hose pipe at once, delivering 930 

 gallons per hour and doing good work with the different mixtures 

 used. This machine was classed the first. 



The next in order of merit was Messrs. Drake and Fletcher's 

 3 HP. two cylinder petrol engine and a set of two-throw plunger 

 pumps mounted on a four wheeled trolley and delivering 600 gals, 

 per hour. 



The other two were: a 5 HP. and a 3 HP. both petrol engines.
