must be air and water tight, they can be kept in cellars, or buried 

 in the ground with perfect safety. Grain could be poured in 

 and then drawn out at will by the Archimedian screw. When 

 the canisters are buried, the wagons of grain are drove over 

 them and readily emptied. Such granaries may be so situated as 

 to accommodate many farms. These canisters may be divided 

 into compartments, with locks, seals, &c., for the different owners 

 of the grain, safe from vermin, wet, fire and thief.

Prof. Mapes. — The melon bug is observed to fly around and 

 about the box placed over a plant, but cannot generally manage 

 to fly into it, so that for the most part our former box coverings 

 of net work, or of glass, are unnecessary, and the grubs cannot 

 get into the box. Scatter some salt about the outside of the box, 

 and the grubs which reach it are killed by the salt. 



Judge Livingston. — We have found useful to save our melons, 

 lime and gypsum, mixed half and half, pulverized and sifted over 

 the melon plants. 



Mr. Paul Stillman. — Snuff and charcoal, mixed, are recom- 

 mended to be sprinkled on the plants. 



The Chairman called up the question of the day (viz ): "Win- 

 ter management of cold frames, winter warming and ventilation 

 of stables, and preparation of fuel." 



Mr. Paul Stillman read a letter from a friend in California, in- 

 quiring how the seeds of water melons succeeded (which he had 

 sent him from melons that weighed sixty pounds each). Mr. S. 

 stated, that he lost all his vines by striped bugs, which, contrary 

 to all theory, attacked his vines after they were loaded with fruit, 

 and by eating the leaves destroyed the whole vines. They did 

 the same thing to his bearing cucumber vines, in September; and 

 he wants to know how to prevent a repetition of their ravages. 



Prof. Mapes. I have never known such old vines attacked. I 

 keep bugs off young vines by a simple four sided box, ten inches 

 square and ten inches high. There is no need of glass or cloth 

 over the top.
