The young plants are Well thinned during the summer ; in 

 the end of October they are very carefully transplanted into 

 forcing-pots, five or six in each pot. They are placed in ^ 

 north aspect, to recover the eftect of their removal from the 

 seed-bed, and in a month they are fit for forcing. We can 

 safely recommend this method. : 



XXII. Account of some remarkable Holly Hedges and Tree^ in Slcotlandl 



By Joseph Sabine, Esq. 



This is an elaborate account of some extraordinary specimens! 

 of hollies, and appears to have been vrritten with a view to 

 induce the more general cultivation in this country of that 

 very valuable tree. At Tynningham, the residence of the 

 Earl of Harrington, are hedges extending to no less a dis- 

 tance than 2952 yards, in some cases thirteen feet broad, and 

 twenty-five feet high. The age of these hedges is something 

 more than a century. At the same place are individual trees 

 of a size quite unknown in these southern districts. One 

 tree measured five feet three inches in circumference at three 

 feet from the ground ; the stem is clear of branches to the 

 height of fourteen feet, and the total height of the tree is 

 fifty-four feet. The other places at which the hollies are of 

 unusual size, are Colinton-house, the seat of Sir William 

 Forbes; Moredun, the seat of David Anderson, Esq.; 

 Hopetoun-house, the seat of the Earl of Hopetoun, and 

 Gordon-castle, where are several large groups of holliesj 

 apparently planted by the hand of Nature. 



XXIII. An Account of a Plan of Heating Stoves by means of Hot Water^ 



employed in the Garden of Anthony Bacon, Esq. 



We conceive that a new aera in horticulture will commence 

 with the publication of this paper. We already possessed 

 contrivances of a sufficiently good kind for all purposes con- 

 nected with artificial climate, except the power of com- 

 manding heat ; for which the two methods hitherto employed 

 have been either too clumsy or too costly, and in either case 

 liable to numerous objections. The old mode of introducing 

 heat into a stove, by means of brick flues, has long been 

 considered so bad, that every scheme that promised to super^ 

 sede such flues has been hailed with joy ; the uncertainty of 

 the quantity of heat given out by a brick flue, its continual 

 liability to explosion, the impossibility of preventing the 

 escape of smoke from between the joints of the bricks, are 

 all evils that require a remedy. For this purpose steam was 

 introduced, and with great advantage in extensive ranges of 

 .hothouses. But the enormous expense of erecting a steam
