286 TEANSACTIONS OF THE ^ 



Mr. Prince said that it was the runners that produced the 

 exhaustion. Tlie fair test was the weight of the berries in two 

 cases. Tliis talk about a multitude of blossoms was of no value. 

 The plant might produce a profusion of little berries. 



Mr. Pardee said that Wilson's Seedling is larger than the 

 Crimson Cone, and as solid and heavy; and, besides, the runners 

 on these Wilson's Seedlings had not been cut off, but allowed to 

 run freely, and form plants all the previous season. So that the 

 test (as far as a single test can be) is a fair one. 



The chairman asked whether the cultivation of the Alpine 

 strawberry was abandoned. 



Mr. Prince said that the markets of Paris are furnished exclu- 

 sively from the Alpine strawberry, which is produced from plants 

 that are sown in April and May. It is prone to produce fruit 

 perpetually. 



THE POTATO ROT. 



Mr. Bergen exhibited some potatoes affected with rot. He 

 stated that the disease is prevailing very generally in Kings 

 county, and also in New Jersey. He had dug 190 bushels from 

 three-fourths of an acre, and of these one-fifth were rotten. The 

 soil was sandy loam. The potato vines have shown evidence of 

 disease very rapidly during the past fortnight. No rot has been 

 visible of any consequence until the heavy rains of last week. 

 This is contrary to what happened two years ago, when the rot 

 succeeded the rains, and on the appearance of dry weather. 



Mr. Field thought there was no great dissimilarity. The fact 

 was, that the rot could not appear until the tuber had obtained a 

 certain maturity. 



Mr. Bergen did not agree with that view of the subject. 



Mr. Field had 20,000 young pear trees struck with the rust. 

 They had almost entirely lost their leaves. 



The Chairman adverted to the purity of the vegetation. This 

 year, in New-Rochelle, up to this date, there were very few 

 insects. The potato vines were healthy. It was strange that in 

 this locality, the neighborhood of New- York, it should be other- 

 wise.
