The Trials of Spraying Machines at Cambridge. 465 
and upon bushes. The “Antipest” is a good instrument, 
modelled on the lines of the Continental “ Knapsack ” machines, 
advantageously used for putting the Bordeaux mixture on vines 
and potatoes in France, Belgium, and Germany ; and the other 
three entries of the same exhibitor had many valuable points. 
But in a country where labour is dear and holdings are large 
they cannot be compared with machines like those of Messrs. 
Boulton & Paul and the Stott Fertiliser, &c., Company, which are 
calculated to spray large areas of fruit land, planted with stan- 
dards, half-standards, pyramids, and dwarfs, and fruit bushes 
that may be set between them, speedily and effectually. 
With regard to the entries of the two firms just named, 
long and repeated trials were made of them, and every possible 
consideration was given to the respective merits of each. No. 
4669, entered by the Stott Fertiliser, &c., Company, is a very good 
machine. Its pump is strong, and with long lengths of hose, 
and the patent nozzle fitted to them, liquid can be thrown high 
enough to spray tall trees. Its draught is fairly light. 
Messrs. Boulton and Paul’s machine is fitted with a very 
powerful and yet most easy working pump, able to force liquid 
great heights. It holds more liquid than the Stott Company’s 
machinery, and it is as readily moved about ; but it must be said 
that it is not so well constructed, except as regards its first-rate 
pump, nor so smart in appearance. The lengths of hose attached 
to it for the trials were not so long, and the nozzles, perhaps, not 
quite so good as those of the Stott machine, but the hose can of 
course be made of any length and any good nozzle may be 
applied. Seeing that there is a very great difference in the 
cost, the Stott Company’s machine being priced at 201. and 
Messrs. Boulton and Paul’s at less than half the price, and that 
the pump of the latter is much superior, it was decided to give 
this the prize, though it must be recorded that the Stott 
Company’s machine has very great merits. 
The official list of awards in the competitions of spraying 
machines will be found in the Appendix, p. clxii. 
The trees and bushes upon which these experiments were 
made are not planted regularly, so that it was rather difficult to 
work the machines. The owner, Mr. Bidgewell, however, placed 
all his fruit plantation at the disposal of the Steward and the 
Judge, and assisted them throughout these trials as well as the 
trials of the distributors of the Bordeaux mixture with the 
greatest assiduity and intelligence.
