202 TRANSACTIONS OF THE 



Solon Robinson remarked that the difficulty in safe transplant- 

 ing of evergreens was not only the mistake as to the time of the 

 year, but in not cutting off the lower end of the tap-root early in 

 the season by som-e implement which can be put into the ground 

 some distance from the plant and cut off the lower end of the 

 tap-root and not disturb the rest of the tree. Then you can 

 remove it the following July with almost sure success. 



Mr. Adrian Bergen, who is an experienced farmer of many 

 years standing, and now busily engaged in farming, said that we 

 are apt to attribute a single failure to bad unripe seed. But as 

 to our Indian corn, it rarely happens to be gathered unripe. 



Mr. Porter said that the injury to the manure in the tank 

 spoken of, was occasioned b}^ its being too tight to admit the air. 

 It was the want of the phosphoric acid. Admit the air and the 

 damage will not occur. 



President Pell said that he had a tank on his farm which con- 

 tained three hundred hogsheads, and that he had caused it to be 

 constructed so as to be perfectl}^ ventilated. He ordered two 

 efficient ventilators to be attached to it. 



Samuel Erwing of New- York, exhibited the Grafton mineral 

 paint. It consists of tiles, very finely pulverised, and is 

 used with oil as other pigments. Much is said in favor of it. 

 Those who wish to try it can apply for information at No. 62 

 William street. New- York. 



W. J. Demorest, of 375 Broadway, exhibited an improved 

 portable magic summer stove for cooking. The fuel is gas of the 

 cities, or a gas generated in itself from alcohol, by means of small 

 wire in masses dispersive of the alcohol, like the Platinum 

 sponge used for intense light. 



Demorests' article is composed of tin or sheet iron, various 

 vessels can be employed at the same time, for the heat is equally 

 distributed — no smoke, and little heat radiated from its exterior — 

 no smell, baking, broiling, boiling, sad iron heating, etc., all go 

 on together. Tha whole little kitchen standing on a table or any 

 where else handy to the operator. No danger from the alcohol, 

 because that is contained in a hollow metal circle below the 

 apparatus, where it cannot partake of the heat at all, and whence 

 its upward supply to the liitle kitchen is perfectly under com- 

 mand by cook. 



Secretary Meigs good humoredly said that this very effective 

 little kitchen in which any batchelor of any age could make his 

 coffee and sausages for breakfast, cook his bit of fish or flesh for 

 dinner, and bake his custard and bread and make tea cakes, and
