American Pomological Congress. — In con- 

 formity with the Resolutions passed at the last 

 session of this National Institution, its next meet- 

 ing will be held in the city of Cincinnati, Ohio, on 

 the 11th, 12th, and 13th days of September next, 

 A. D. 1850. 



The Ohio State Board of Agriculture, and the 

 Cincinnati Horticultural Society will also hold their 

 Annual Exhibitions at the same time and place, 

 and the latter has generously offered to provide 

 lor the accommodation of the Congress. 



All Agricultural, Horticultural, Pomological, 

 and kindred societies in the United States and the 

 Canadas, are hereby respectfully invited to send 

 such number of Delegates as they may deem ex- 

 pedient. 



In order to facilitate the objects of the Associa- 

 tion, to promote Pomology and the sciences upon 

 which it depends, to collect and diffuse a knowledge 

 of researches and discoveries in this important 

 department, delegates are requested to bring with 

 them specimens of the fruits of their respective 

 districts, with lists of the same, and also papers 

 descriptive of their art of cultivation, of diseases 

 and insects injurious to vegetation, of remedies for 

 the same, and whatever will add to the interest 

 and utility of the Convention. 



Packages of Fruit not accompanied by its pro- 

 prietor, may be addressed to the care of Messrs. 

 John F. Dair & Co. Lower Market Street, Cin- 

 cinnati, 0. These should be very distinctly mark- 

 ed " For the American Pomological Con- 



GRE S." 



Ail Societies to be represented in this Congress, 

 will please forward certificates of the election of 

 their several Delegations, to J. B. Russell, Esq., 

 Corresponding Secretary of the Cincinnati Horti- 

 cultural Society. Delegates will also report them- 

 selves at the Burnet House, on the morning of 

 the 11th, where a Committee will be in attendance 

 to take charge of their Fruits, and from whence 

 the Congress will proceed to the Hall assigned 

 for its meetings. Marshall P. Wilder, Pres- 

 ident. S. B. Parsons, P. Barry, and George W. 

 Deacon, Secretaries. July 4, 1850. 



Vineries. — I last fall constructed a small 

 house as a cold vinery, and wish to inquire 



whether there are any advantages in white- 

 washing the inside of the glass? I have noticed 

 that with some green-houses this is done in 

 summer. I am induced to make the inquiry as 

 my vines seem to suffer from the heat of a blight 

 sun. I wish also to inquire of whom I can pro- 

 cure the Diana grape for fall transplanting. C. 

 P. Williams. Albany, 3d July, 1850. 



No ordinary amount of light or sun will in- 

 jure a grape vine, provided tiiere is moisture and 

 food enough at the roots and ventilation enough 

 above the leaves. Your vines probably suffer 

 from the want of one or the other of these need- 

 ful things. The Diana grape will no doubt be 

 advertised by various nurserymen this fall. Ed. 



Strawberries, &.c. — Sir: I am a constant 

 reader of the Horticulturist, and have been 

 highly gratified with it from the beginning. 

 The subject which is mv favorite, is the straw- 

 berry, which I have made a matter of study. I 

 have fruited about ten varieties in my garden 

 this summer, and some of them fully equalled 

 my expectations. Among the best are '• Bri- 

 tish Queen," (I think the genuine,) Hovey's 

 Seedling, Burr's New Pine, Black Prince, 

 Burr's Rival Hudson, and Columbus. All 

 things considered, I prefer Myatt's British 

 Queen. It is equal in beauty and flavor with 

 Hovey's Seedling or Boston Pine, and more 

 hardy, and I think rather 7nore prolific than 

 H.'s Seedling. In your "Fruits and F. Trees," 

 you are fearful that the British Queen will 

 prove tender. I do not find it so; but I cover 

 them with coarse manure or forest leaves in 

 early winter. Strawberries in general suffer 

 nothing in winter, except by alternate thawing 

 and freezing in March, by which the roots are 

 loosened and laid bare. I am not a dealer in 

 plants, and what few will set in my margin are 

 spoken for. I obtained a half dozen (B. Queen) 

 two years ago in September, of Dr. Voorhies. 

 of New Rochelie. I think your correspondent 

 in Poughkeepsie may get some from him, who 

 told me he had them of W. R. Prince, and has 

 cultivated them three or four years. By the 

 way, I happened to be lingering in New-York, 

 in October last, and took a trip to Flushing,
