with duties added, of over $12,500,000 ; raw fruit and raisins, do., 

 $3,700,000 ; to which add at least fifty per cent to cover transportation, 

 waste and profits before reaching the consumer, say $8,000,000, and 

 it foots up the snug sum of $24,200,000. Is not this a field worth 

 occupying by home labor and capital? 



In this connection, several boxes of Catawba grapes were distributed 

 by Mr. D. S. Wagner. They were in excellent condition ; and in 

 answer to questions, he stated that he had preserved twelve tons of a 

 like character. His plan is to keep them on shelves in a dry, air- 

 tight room, keeping up an even temperature, and he regulated the 

 temperature by opening windows. He found that the grapes would 

 stand twenty-six degrees of cold without injury. 



Bkook Trout. 



Mr. S. A. Phillips, Royalton, Wisconsin — Trout are found in the 

 streams flowing into Green Bay, and also in the west part of this 

 State ; but on the Wolf and its tributaries none. The water here is pure 

 as crystal, and springs abundant, well stocked with other fish. The 

 water is what .is usually termed " hard," and lime is precipitated 

 when it is boiled. Will this fact alone prevent the successful culture 

 of trout, other conditions being good ? 



Mr. A. S. Fuller — Trout abound in the streams of western New 

 York, all of which flow over limestone. 



Dr. J. Ware Sylvester — The same is true in Wayne county. 



Mr. Bragdon — I have often caught trout in the limestone streams 

 of Jefferson county. The reason why trout do not exist where the 

 streams become large is, that large fish eat them. 



Mr. Henry Stewart — In this gentleman's section the trout are all 

 destroyed by too close fishing. 



Prof. H. Et Colton — In the southern Alleghanies, it is generally 

 thought trout will not live in limestone streams. I know that in 

 some streams flowing from North Carolina into East Tennessee, the 

 trout cease as soon as the geological divide is crossed. I suppose the 

 real reason is, that the limestone lands are generally rich and level, 

 and hence from cultivation and wash the water becomes muddy. I 

 believe it is generally conceded that speckled trout do not like muddy 

 water. 



The Best Floor for a Cheese Factory. 

 Mr. Geo. West, Cannon Falls, Minn. — We have failed twice in the 

 attempt to make a cement floor for the manufacturing-room of a
