the leaves and fibres, and fibres in circumstances which 

 admit of removal without rupturing them ; hence, transplant- 

 in^ can be performed without any great check to the plant, 

 and as a result of such plants sown in January in a stove, 

 and planted out in the beginning of April, Mr. Knight had 

 a crop of carrots "nearly a month earlier" than he could have 

 had by the ordinary means of cultivation. We should like 

 very much to see this experiment repeated by a practical 

 gardener, and to see turnips tried in the same manner. Beet 

 and Swedish turnip may be successfully transplanted, even 

 when the points of the roots are broken or cut off. The check 

 would be lessened by Mr. Knight's plan, and hence possibly the 

 common turnip might be sown in pots and transplanted. Inde- 

 pendently of an early crop, this would sometimes be of value 

 for filling up blanks, both in gardens and fields. 



35. First Report on the Experiments carried on in the Garden of 

 the Horticultural Society of London ; made up to the end of 

 March, 1825. Read February 7- 1826. 



The greater part of this paper consists of descriptions of 

 hothouses and pits, erected in the garden of the Society, 

 probably for the purpose of showing to the subscribers to the 

 garden how the funds have been expended, but certainly pos- 

 sessing very little novelty or interest in other respects. A 

 justly-merited tribute is paid " to Mr. William Atkinson, to 

 whose advice and assistance in the construction of the build- 

 ings in the garden the Society is much indebted ;" and this 

 gentleman's mode of ventilating hot-houses is commented 

 upon, not as " absolutely new, but because the method is 

 not so much adopted as it deserves to be." We entirely 

 concur in this opinion, and consider Mr. Atkinson as the very 

 first hot-house architect. His principal improvements in 

 regard to heating and ventilation, and his very superior 

 manner of constructing flues, &c, will be found described in 

 " Tredgold on warming and ventilating Divelling-houses, Con- 

 servatories, fyc." a work which we have elsewhere (p. 118.) 

 said ought to be in every garden-library; and we shall here 

 give the description of the mode of ventilation alluded to in 

 the report. 



" In the first place, the roof is not provided with movable sashes, but 

 they are, on the contrary, fixed : there is necessarily no upright glass in front 

 of the house ; but the roof rests there upon the solid wall {fig. 59. a), and 

 at back upon the face of the back wall, (b) In the front wall are built a 

 number of wooden frames, into which shutters, opening externally on hinges,
