Gum Scammony 



Is the milky juice, or gummy resinous exudation of a plant of 

 the Convolvus tribe; it is exceedingly difficult to get it genuine. 

 The consumption of it is not large. We imported into England 

 in 1853 on 9,704 pounds, and nearly all from Turkey. 



Terra Japonica. 



Much valued for tanning, dyeing, and is the product of the 

 leaves and branches of the Uncaria Gambia of Roxburgh, cultiva- 

 ted chiefly at Singapore by the Chinese, and of which our imports 

 average upwards of 91,000 cwts. per annum. 



The President called up the first question of the day, viz : by 

 Dr. Waterbury, " Winter feeding of stock." 



Dr. Waterbury — I proposed that question and also the appoint- 

 ment of a proper committee to examine the extensive system of 

 this city in relation to the vast number of horses and mules used

 When the committee has acquired the required statistics it will 

 report to the Club. I therefore move a postponement to the next 

 session of the Club. Carried.

 are all brought edge to wind and suffer no injury. 



Dr. Wellington asked members to express their opinions as to 

 the relative value of vegetables for feed of stock. 



Thomas W. Field of Brooklyn, asked the president as to the 

 use of apples as feed for hogs. 



The president said that he hsfti experimented with the apples, 

 of which the product of the Pelham farm was large; he had fed 

 two of the animals entirely with apples; one day with sour ones 

 and the next day with sweet ones. On killing them, their pork 

 was found to lose about one-third of its weight in the boiling. 



Mr. Field — believed that the evidence from the western country 

 was that apples fed with corn and other feed made excellent pork. 



Dr. Wellington spoke of Phinney's prize farm in Massachusetts, 

 and Ills experience in turnip feed for hogs; he raised many, and 

 from three hundred pounds to nine hundred pounds weight 

 a piece, and he had fed them freely with apples. That to pre-
