house plants, and also the glass-houses of 

 Horace Gray, the most extensive then 

 known in the United States, in which 

 were annually produced enormous quan- 

 tities of the choicest foreign grapes. The 

 property afterwards came into the posses- 

 sion of Mr. W. C. Strong, who, under one 

 continuous roof of glass, containing 18,- 

 ooo square feet, raised a great abundance 

 of roses, carnations, and other flowers 

 that were sent to the markets of New 

 York and Boston. 



On the estate of Mr. Hunnewell at 

 Wellesley, the conservatories and houses 

 devoted to every variety of plant life, 

 and known far and wide for the methodi- 

 cal manner in which they are constantly 

 maintained, have been previously noticed. 



At the present day, the amount of the 

 horticultural productions under glass cul- 

 ture in Massachusetts, especially about 

 Boston, is almost beyond calculation, the 

 markets being thereby abundantly sup- 

 plied with the greatest variety of vege- 

 tables and the smaller fruits.
