entomology, for he fully realizes how much there is yet to 

 learn of some of the commonest insects destructive to the 

 vine, even in an old country like France. But in no direction 

 has he accomplished as much good as in his work with insec- 

 ticide and fungicide machinery. His sprayer with indepen- 

 dent pump, his diaphragm pump — L'Eclair — and his reservoir, 

 with suction and force pump, are all admirably adapted for the 

 purpose they were invented for and may be obtained in France 

 at a cost from $5 to $7, which is tripled before reaching this 

 country, thanks to our present tariff system. 



''The last number of the Journal of Mycology, the serial 

 publication of the Division of Vegetable Pathology of the De- 

 partment of Agriculture, gives full description, with figures, 

 of a knapsack spraying apparatus, for which the special merit 

 claimed is cheapness, and which is named the Galloway 

 sprayer. 



''The combination of a suction and a force pump with knap- 

 sack reservoir has been frequently made in France, as illus- 

 trated by the apparatus styled the ' Cyclone' of Vermorel ; the 

 Japy, Vigeroux, Nouges and Perrin sprayers, and the sprayer 

 of the society L'Avenir Viticole. A number of pumps manu- 

 factured in this country of this style were mentioned or de- 

 scribed in the Fourth Report of the U. S. Entomological Com- 

 mission. These, in general, are much inferior to the French 

 pumps named, which are, however, modeled after those 

 earlier and cruder forms. There are a host of other French 

 knapsack spraying machines which differ from those men- 

 tioned, by propelling the liquid by means either of air pumps, 

 diaphragm pumps, or devices in which the pump is attached to 

 the reservoir by means of a rubber hose. 



"In 1888 Adam Weaber, of Vineland, N. J., brought out the 

 Eureka sprayer, a very serviceable knapsack pump modeled 

 after the French machines. The French sprayers will cost, 

 including duty, shipping, etc., from $18 to $25; the Weaber 

 sprayer is sold for $21, which is but little more than the cost 

 of manufacture. Professor Galloway's machine is sold for 

 $14, or from one-fourth to one-third less than the Weaber or 

 the French sprayers. 



" In the first announcement of this pump in No. i, vol. 6, of 

 the publication cited, and in the later full description, no state- 

 ment is made of the indebtedness of the inventor to these older
