AMERICAN INSTITUTE. 275 



Prof. Mapes— It always requires a division — its particles must 

 be perfectly separated to do well. We should mix — mix care- 

 fully before we apply it. 



Mr. Moore— I have seen in Ohio, the grape-vines in a vineyard 

 only foui' feet apart every way on the whole vineyard. No growth 

 allowed among them. 



Prof. Mapes— I raise many sorts of crops between my rows of 

 vines. 



Mr. Moore— I have tried corn between mine. I have used 

 bows for my vines as well as stakes— one stake or two bows to 

 each vine. I found wire trellis bad for some of my vines— the 

 tendrils injured by the hmt of the wire in very hot days. 



John D. Ward, Esq., of Jersey City, presented specimens of 

 the water of that city's aqueduct from the river Passaic. It was 

 tasted by members, and pronounced very good. 



Mr. Ward, who has been principal in the introduction of this 

 great blessing into Jersey City, states that upon a careful analy- 

 sis this water is found to contain about twenty per cent, less of 

 solid or inorganic materials than the water of our Croton aque- 

 duct. ^ 



The Club warmly expressed its pleasure at the accomplishment 

 of this noble aqueduct, and gave all honor to Mr. Ward and his 

 associates who have done it. 



Paul Stillman called for glasses of the Passaic water to drink 

 the health of Mr. Ward, which was done heartily. 



A conversation ensued relative to a proper coating for the iron 

 wire trellis. 



Prof Mapes recommended a coating of gutta percha and white 

 oxide of zinc melted together. It forms an enamel on the wire. 



Orange Judd— Some have supposed that plants are injured by 

 applying hot water. That is true of mere plants, but not of 

 trees. At a lady boarding house in New Haven, Conn., some 

 little time ago, a catalpatree in the yard was pointed out to me as 

 being in better condition tlian usual, a grape vine, a Catawba also, 

 and both had been sometimes treated with doses of boiling water 

 about their feet. As to the wire fence, I found on William R. 

 Hazard's farm a considerable extent of it in good condition, made 

 of wire Nos. 7 and 8, with seven wires in the fence, strained up 

 occasionally at the strong posts, 40 rods apart, by a wrench. 

 Some of it had stood well three years, other posts seven years. 

 Cost, fifty cents a rod. 



The Chairman called for questions for next meeting.
