The twenty-six hand power machines were, after the exhaustive 

 trials on the first day, reduced to eight, and of these the first place 

 was taken by Messrs. Weeks and Son's machine consisting of a 

 35 gallon wooden container mounted on side wheels with a gun 

 metal pump fitted with ball valves. The second place fell to" 

 Messrs. Drake and Fletcher's machine consisting of an oval shaped 

 barrel of 18 gals, capacity mounted on a barrow frame with ball 

 valve pump. 



The others also were very good machines. 



Some knapsack machines were also entered, a form not intended 

 to be included under the regulations. 



Of the nozzles used in the trials, the large " Seneca " pattern 

 was found the best for lime and salt spraying; and for the Bor- 

 deaux mixture Messrs. Weeks and Son's " Multispray," the "Mistry " 

 and the " W. E. K." did the best work. As a general purpose 

 nozzle Messrs, Drake and Fletcher's adjustable " Mistifier" was very 

 satisfactory. 



THEOBALD. Spraying against Apple Sucker (i). Journal of 

 South-Eastern Agric. Coll., No. 17, Wye, 1908; The Jurnal of 

 the Board of Agric., Vol. XVI, No. n, p. 935. London, Fe- 

 bruary 1910. 



The life history of the Apple Sucker is given by Mr. Theobald, 

 together with a description of various experiments and trials with 

 the lime and salt wash. Experiments were carried out at Wye in 

 1907 and 1908 to find a cheap sticking medium to make the lime 

 adhere more firmly to the bark, but no very satisfactory results 

 were obtained. 



Mr. Theobald gives the following summary of conclusions as 

 regards this wash: Lime and salt wash (i x / a cwt. fresh lime, 

 40 Ibs. salt, to 100 gallons of water) prevents the hatching of large 

 numbers of the apple suckers, its effect varying according to the 

 thickness put on the trees, the thoroughness of the application, and 

 the extent to which it has dried before rain comes. No ingre- 

 dient yet known prevents to any great extent the flaking-off of 

 the lime on smooth wood. Waterglass or paraffin to some extent 

 causes it to hold slightly better. Up to 40 Ibs. of salt maybe used
