AMERICAN FRUIT 'EVAPORATORS AND EVAPORATING. 539 



£16. No. 2 (fig. 36) is of rather more than double the 

 capacity of No. 1 ; price £21. The evaporators of a larger 

 size are called " commercial sizes." Of these No. 3 has a 

 drying capacity of 300 square feet, and is capable of drying 

 from forty to fifty bushels of apples daily ; the price is £52. 

 Nos. 4 and 5 are much larger in size, as may be judged from the 

 prices, which are respectively £104 and £135. No. 5 is equal to 

 drying 150 bushels of apples every twenty-four hours. All 

 through this paper a day may be taken to mean twenty-four 

 hours, as it seems clear to me that the usual plan is that when 

 an evaporator is set at work in the States it is kept going night 

 and day. Except the furnace fittings, the " American " evapo- 

 rators are chiefly made of wood, which the makers claim to be 

 the best substance for the purpose, and it is stated that the 

 insurance record shows that they are quite safe from injury by 

 fire under ordinary circumstances. 



The prices quoted by Messrs. Ph. Mayfarth & Co. for the 

 various sizes of the " American " evaporator are somewhat less 

 than those given above : thus No. 1 is quoted at £13 instead of 

 £16. This evaporator has been exhibited at several agricul- 

 tural shows in this country ; and one has been at work at 

 Well Place Farm, Penshurst, Kent, for some time ; also at the 

 " Invicta " Works, Maidstone; and satisfactory reports of the 

 work done have appeared in the local papers. This evaporator 

 was exhibited at the Royal Agricultural Society's Nottingham 

 Show in 1888 ; and at the Windsor Jubilee Show in 1889, where 

 it was awarded the Society's prize, value £30. The size which 

 won this prize was the No. 2 evaporator (the fig. 36 in my 

 sketch). In vol. 1. pp. 494-6 of the Royal Agricultural 

 Society's Journal (1889) there is a most favourable report on 

 the trial made at Windsor, where the judges appear to have 

 been quite satisfied with the performance of the " American " 

 evaporator. 



The Journal of the Royal Agricultural Society for October 

 1888 (pp. 490, 491) contains a paper in which there are some 

 interesting particulars about fruit evaporation, and as the author 

 is Mr. D. Pidgeon, a civil engineer, officially connected with the 

 Royal Agricultural Society, I feel I may commend what he says 

 on the subject to everyone interested. He contributed another 

 paper on the same subject in the first part of the third series of
