pides. Soiiio years at:;o, the followinfj calcu- 

 lations, respecting the prevaK'iico o( certain 

 winds, were nuiile by tlio l\oyal Society of 

 London ; and are worthy the consideration 

 of tiioso engaged in horticultural, as well ns 

 even agricultural pursuits. Jn England, the 

 following are the number of days from which 

 the winds specified blow : —

"Westerly winds seem to prevail most in 

 the months of July and August ; north-east 

 during those of January, March, April, May, 

 and June ; north-west from November till 

 March. The north-east wind is less fre- 

 quent during Fcbruar}^ July, September, and 

 December ; and the north-west less frequent 

 during September and October, than iu any 

 other months. 



As similar calculations have been made in 

 the neighbourhood of Glasgow, the following 

 table may serve for the west of Scotland : —

In Tveland, tlic prevailing winds are the 

 west and south-west. 



AVhilst these tables may assist in enabling 

 us to determine the quarters in which the 

 garden requires the greatest shelter or pro- 

 tection, Wo» may observe that this may not 

 uafrequently be derived even from the natural 

 shape and situation of the ground. It is ob- 

 served by Neiil, that gentle declivities at the 

 bases of the south or south-west sides of hills, 

 or the sloping banks of wii;ding rivers with a 

 similar exposure, are very desirable. If plant- 

 ations exist in the iieiglibouihood of the 

 house, or of the site intended tor the house. '

tho de.sigticr of a garden naturally turns hia 

 eye upon tlani ns tlic nu-ans of hia principal 

 shelter. Hi- takes care, however, that his 

 ground hhall be chosen at bucIi a dislauco 

 from then> as will prevent his fruits from being 

 shaded by thorn. If the [tlanlations bo young, 

 and contain beech, elm, oak, and other tall- 

 growing trees, allowance, as a matter of 

 course, is made for this in tho meaHurement 

 of tho distance. It is a rule, however, that 

 there should be no tall trees on tho south of a 

 garden, except at a considerable distance. 

 This has been suggested from tho fact, that 

 during winter and early spring, they fling 

 their long shadows into the garden at a time 

 when every sunbeam is a welcome visitor. On 

 the east, also, they must be sufficiently re- 

 moved to admit the orient beams of the early 

 morn ; but on the west, and more particularly 

 on tho north, trees may be suffered to be 

 nearer — say, perhaps, within about a hundred 

 feet— and they may be more clustered. 



HOT-HOUSES. 



It is frequently a matter of choice as to 

 where the hot-houses e.hall be placed in a 

 kitclien garden ; but in extensive establish- 

 ments, a whole garden, or walled enclosure, is 

 sometimes entirely devoted to the cultivation 

 of the products belonging to this department 

 of horticulture. This is the case both at Kew 

 and at Frogmore ; but in places of more 

 moderate dimensions, the hot-houses either 

 find a position against the north wall of the 

 garden, or against some of the cross-walls, 

 which, here and there, partially intersect ita 

 area. Occasionally they are placed in the 

 slijy, which has greater width accorded to it 

 for that purpose, either on the east or west 

 sides of the garden, or on tho north, where 

 there may chance to be a favourable declina- 

 tion of the ground. It is the opinion of iMr. 

 Loudon, however, that their efl'ect is always 

 best when they are situated witliin the boun- 

 daries of the garden proper, either attached 

 to, or on, the north of the cross-walls. "In 

 this way they are sources of greater interest 

 to the proprietor, and come more naturally 

 into the general course of promenade than by 

 any other arrangement ; for it must not be 

 forgotten that the pleasure or satisfaction 

 derived from even culinary hot-houses, does
