THE STRUCTURE AND MANAGEMENT OF GREENHOUSES. 59 



"been made implying tliat flues are not witliout merit. In large 

 establishments, where only one kind of plant is cultivated in a 

 house, an even temperature is wanted, and in such a house 

 flues are unsuitable. The first house that he built was sixty feet 

 long and was heated by a flue, and the results were ver}' satisfac- 

 tory. He grew at the cool end anemones and similar plants. 

 He would heat a long and narrow house with a flue now. 



Mr. Strong thought the flue system antiquated, and did not see 

 why we cannot get all the advantages of it with hot water. Bj' 

 the latter method the heat can be concentrated where it is wanted, 

 and he thought it could be distributed more advantageously. 



Benjamin G. Smith said that he has an octagonal conservatory, 

 fifteen feet in diameter, attached to his dwelling-house, which he 

 bas heated with a Wethered boiler and two-inch wrought-iron 

 pipes in a satisfactory manner. 



Mr. Temple said that with a small house and a variety of 

 plants one must have some means of producing different tempera- 

 tures. If hot water can be arranged to produce this it will do, 

 but flues are much cheaper. If carefully built they will not leak. 

 He would build the first fifteen feet of brick, laid very carefully, 

 and beyond that of glazed drain pipe put together with cement. 



It was announced that on the next Saturday, J. B. Harrison, 

 Secretary of the American Forestry Association, Franklin Falls, 

 N. H., would speak on " Forestry as applied to Massachusetts."
