THE FLORAL WORLD AND GARDEN GUIDE.

ment to any earnest amateur or pro- 

 fessional gardener. It must be re- 

 membered, that in the Northern States 

 of America, European vines are of no 

 use in the open air, owing to the se- 

 verity of the climate. If the native 

 vines yield abundantly, and if their 

 produce is eminently adapted for wine 

 making, it follows that, in the more 

 genial climate of the southern coun- 

 ties of England and Ireland, those 



same American vines would be more 

 likely to afford satisfactory results 

 than the varieties we have hitherto 

 regarded as the hardiest. Nay, we 

 do not see why, even to the Orkneys, 

 the American grapes should not be 

 found adaptable : for on their prairies 

 and mountain slopes they have to en- 

 dure severe winters, and they appear 

 to be partial to a dry, poor, rocky 

 soil.

GREENHOUSE 



Aftee May, the house would be 

 kept warm enough by shutting in the 

 sun heat ; that is, not giving too much 

 air to allow the heat thus derived to 

 be as rapidly dissipated. A very 

 good maximum throughout the sum- 

 mer would be seventy-five degrees, 

 and sixty degrees as a minimum would 

 be near what would suit the plants. 

 Of course the temperature would vary 

 according as the days were sunny or 

 cloudy, but this would not injure the 

 plants. During much of the summer, 

 too, the air is mild and balmy, and 

 then ventilation may be freely per- 

 mitted even for a considerable part of 

 the day, and sometimes, when very 

 warm, slightly all night ; at other 

 times, when the air is cold, it is not 

 at all material to give much air, or 

 even if none is admitted formally, for 

 some few days together, it will cause 



but little difference to the plants. In 

 the latter end of the summer, how- 

 "ever, it is desirable to give air more 

 freely. Throughout this season of the 

 year, the watering and syringing must 

 be kept up regularly. By the end of 

 September, a change must be com- 

 menced. There will naturally be 

 less heat, and there should be less 

 water artificially applied ; this must 

 be broken off gradually in the same 

 way it was commenced in spring, so 

 that by the beginning of November 

 the plants and soil may be in that 

 comparatively dry state we have 

 already endeavoured to describe. 

 Throughout this early part of tho 

 autumn, air should be very freely ad- 

 mitted throughout the day, to keep 

 the temperature cool, and to help in 

 passing off extraneous moisture and 

 drying the interior of the house.

COOL STOVE AND GREENHOUSE ORCHIDS. 



The subjoined is, we believe, the 

 most complete list yet prepared of 

 orchids which may be grown to per- 

 fection by cool treatment. The list, 

 which appears at page 115 of the 

 " Garden Oracle" for 1865, will be of 

 immense value to beginners, as com- 

 prising only such kinds as may be 

 obtained at low prices, and which are 

 among the most beautiful orchids 



known. This larger list will be 

 chiefly useful to those who have 

 already made some progress in orchid 

 culture : — 



Epidendrum macrochilum, E. m. 

 album, E. m. roseum, E. atropurpu- 

 reum, E. vitellinura, E. v. major, E. 

 aurantiacum. 



Leptotes bicolor.
