mossy unique, was originated at Clifton ; and the beautiful Rosa cristata in 

 Switzerland. The Rose unique was discovered at the commencement of the 

 present century, in a cottager's garden, among a plantation of roses ol the 

 hundred leaved or cabbage, kind, which is peculiarly subject to sport, either 

 from the excessive vigour or imperfect vegetation of the subject. The mossy 

 rose de Meux, or pompon mosseux was discovered five and twenty years 

 ago, in the garden of an old lady in the west of England, of whom it » as pur- 

 chased by a nurseryman for five guineas ; certainly a sport, as the rose de 

 Meaux is known never to bear seed in England. The Ayrshire roses were 

 chiefly obtained from seed at Dundee, in Scotland. Brown's superb blush 

 was raised at Slough, near Windsor ; a seedling of the Rosa indica odorata, 

 and the yellow sweet briar, at Pitmaston, by Mr. Williams. To enter into 

 the origin of even the finer modern varieties would, however, be an endles* 

 task." (p. xiii.)

A Practical Treatise on Constructing and Heating Horticultu- 

 ral Buildings — By J. W. Thompson. Published by Groom- 

 bridge, Panyer Alley, London. 



This valuable Treatise being the production of a celebrated 

 gardener of long experience, and of well known scientific and 

 practical attainments as an horticulturist and landscape gardener, 

 we think it a duty we owe to all horticulturists, whether amateur 

 or gardener, to direct their attention to this little publication; no 

 gentleman having a hothouse to manage or build, or to heat with 

 hot water, or by any other mode of raising temperature, should 

 be without this truly instructive work. 



Thompson's observations are the result of long experience, and 

 in our opinion the conclusions he has arrived at for the manage- 

 ment of hothouses, Sec, must accord with the views of every 

 practical gardener. His observations relative to non-practical 

 garden architects being consulted on horticultural erections, and 

 his strenuously advocating the cause of every practical gardener 

 interested in these subjects, should inspire in their breasts a feel- 

 ing of gratitude, and induce them in return, to render him every 

 assistance in their power by introducing his plan of boiler for 

 heating with hot water. 



We observe that the opinions of ' The Civil Engineer,' and 

 'The Mechanic's Magazine,' who have written on his plan of 

 boiler, is in accordance with our own, and they fairly admit it to 

 be the best and most economical system yet known for heating 

 with hot-water. 



We consider his conclusions at the end of the work, for the 

 management of hothouses, &c, to be founded on sound philoso- 

 phical, and practical reasoning.
