accidental fissures of the flues. These contingent causes 

 may, however, be in a great measure avoided by good work- 

 manship and material. The hygrometric vapors of the at- 

 mosphere are not decomposed by this system of heating as 

 by a hot-air furnace, because, when the flues are warmed to 

 a common temperature, the heat is perfectly pure, and the 

 materials of which the flues are built, having but little 

 affinity for oxygen, they are consequently more healthy 

 than hot-air stoves.

Art. II. Descriptions and Engravings of Select Varieties 

 of Cherries. By the Editor. 



We now continue our descriptions of the diff'erent varie- 

 ties of cherries, after the lapse of a year, in consequence of 

 the entire failure of the crop in the vicinity of Boston, in

 when we gave an account of three varieties, in addition to 

 three in the previous volume, (1847.) In the present vol- 

 ume we hope to add several to the list, and another season 

 to complete the entire number of really valuable cherries 

 worthy of cultivation.

It is somewhat remarkable, that a cherry possessing so 

 many superior qualities as the Elton, [fig- 21,) and intro- 

 duced into our gardens so long ago, should yet be so little 

 known or disseminated. It was one of the seedlings of the 

 late Mr. Knight, president of the London Horticultural So- 

 ciety, raised in 1806, and scions of it were forwarded to the 

 Hon. John Lowell as early as 1823 ; yet it is, comparatively 

 speaking, a new cherry. The fruit is rarely, if ever, seen 

 in our markets, and it is seldom that it is shown at the 

 exhibitions of our horticultural societies. Varieties unwor-
