OBSERVATIONS ON A CALCAREOUS MOUXTAIN%

will pusli immediately upon being removed into brisk heat, 

 and may be brought to flower as early as May. 



According to the abovementioned distances, half a quar- 

 ter of an acre would contain 15,125 roots, leaving nearly as 

 much space for the alleys as the beds, which, at 3d. each, 

 amounts to the sum of £l89 1^. 6d. and as when a sufficient 

 stock of offsets to select the largest was obtained, the annual 

 return of blowing roots may be estimated at half the number 

 planted, the profits of a bed of tvberoses, after deducting 

 every expense of rent, dung, and labour, would be consider- 

 able, even if it were necessary to cover it in autumn and 

 Ibices favour- winter with three light frames. There are many places in 

 kbleforit. ^yp Island where 1 should imagine this plant might be cul- 

 tivated with still less care and attention, especially in the 

 southern counties near the sea; in the vicinity of London. 

 Ham Common, Sunbury, and Walton upon Thames; in 

 the Isle of Wight; about Southampton; below Exeter; 

 Bath and King's Weston; in South Wales: and the theory 

 which I would recommend any intelligent gardener to adopt 

 in its general management is, to keep the roots growing as 

 vigorously as possible from May to October, but in a state 

 of complete rest and drought for the remainder of the year.

Geological Remarks on a calcareous Mountain near Chessy,

JL Do not think there exists a natural fact, or an obferva- 

 tion however slight, that does not merit the attention of the 

 geologist, who should study incessantly the voluminous book 

 that Nature has laid open before his eyes. Certain pages of 

 tills book it is true may appear but little interesting; yet he 

 should not pass over a single one if possible, would he attain 

 an accurate knowledge of the interesting history of our globe, 

 and the wonderful revolutions it has undergone. A mountaiti,
