it in 1822 to the Horticultural Society. In the year 1824, it 

 produced a crop of fruit in one of the houses in the Chiswick 

 garden, which ripened within fifty days from the time the 

 blossoms opened." 



Mr. Knight thinks it may ultimately become an acquisition 

 of considerable value. Some attempts by him to propagate it 

 by budding, and from seeds, failed, as did also an " intention 

 to have obtained a very early crop of cherries," by his going 

 from home a few days at the time he " proposed to intro- 

 duce the plant into the pine stove." Mr. Knight observed 

 that this cherry put out very numerous roots from the bases 

 of its young branches, similar to those often emitted in moist 

 hot-houses by the vine ; he thence inferred that it might be 

 propagated by cuttings, and, .having planted some, he states : 

 " I have proved that plants may be thus raised with perfect 

 facility." 



19. On the Culture of the Pine-apple. By Mr. James Dall, Gar- 

 dener to the Earl of Hardwicke, F.H.S. at Wimpole. 



The soil used by Mr. Dall is brown loam, two and a half 

 parts, leaf mould one part, and sheep's dung reduced to 

 earth one part. Bottom heat 88° to 100°; atmospherical 

 heat during nights 60° to 70°, during sunshine from 12° to 

 15° higher. Suckers potted in June, in pots five and a half 

 inches in diameter, were shifted into pots a size larger in 

 October ; again shifted in March, and the earth shaken from 

 the roots ; shifted in the July following ; and, in the October 

 of the second year, shifted into the pots destined for them to 

 fruit in. " The size of the pots at this shifting was about 

 twelve inches in diameter, and two and a half feet deep." After 

 renewing their bark-bed, the pots are plunged little more 

 than half their depth, and some time afterwards, when there 

 is no danger of burning the roots, fresh dry tan is filled in 

 between the pots as high as their tops. " For the more safe 

 and expeditious manner of filling tan round the pots that are 

 partly plunged in the bark-bed, as here stated, a pipe or 

 funnel made of sheet-iron is used; the mouth that receives the 

 tan is fifteen inches', and the lower end four and a half inches' 

 diameter, with two handles fixed to it, so that the operator 

 easily holds it while a lad is filling in the bark from a flower- 

 pot." The water used for watering the plants is never less 

 than 80° or 85°; in warm weather they are watered over- 

 head. Always after shifting the plants are shaded during 

 the heat of the day for at least a fortnight. The deep pots
