toTy, is that wLich involves the removal of larj^e quantities of soil. With many of 

 our im)d(.'rii imj)rovcrs, to grade and level «eenis to be synonymous with taste and 

 beauty. There are, however, instanees where artificial elevation.s and depressions 

 are strikingly valuable. We have seen two walks running nearly parallel, only a 

 few yards apart, completely hid from each other by the intervening space, being 

 elevated and planted as in the Derby arboretum, &c. The effect of several years' 

 growth may thus be obtained in a day, and walks brought (juite near each other 

 without being obtrusive, or out of place. Shrubbery, to be effective, must be 

 thickly planted. Plant with a view to a periodical thinning out of the least desira- 

 ble kinds. Our shrubberies are all too thin; they cover too much space. We have 

 seen wonderful effects produced in grounds where all appeared scattered and confused, 

 by simply gathering in a few of the outside plants and placing them in the main 

 body. In planting with reference to future thinness, the experienced planter will 

 find no difficulty in locating each kind in its proper situation, both with regard to 

 future and immediate effect; for however desirable it may be to fonu a feature 

 which will stand as an example for future admiration, it is no less desirable that we 

 should endeavor to supply the wants and claim the approval of the present. 



The style of the building invariably suggests the method of arrangement, as well 

 as the most suitable trees and shioibs for its immediate vicinity. The house being 

 the principal feature in the composition should be treated as such, and trees of the 

 largest growth may be placed in connection. Both the kind and quantity of this 

 class of trees will, of course, depend upon the size of the building and extent of the 

 grounds. Shade is indispensable to a pleasant country residence. The introduction 

 of trees, therefore, combines effect and utility in an eminent degree. We shall 

 probably recur to this subject, with a select list of trees and shrubs for a place of 

 moderate extent. 



THE AQUARIUM. 



BY THE EDITOR. 



Some years since much interest was created by the invention of Dr. Ward for 

 growing plants in closely glazed cases. It afforded much pleasure to scientific per- 

 sons and to invalids, and was altogether a valuable and instructive in-door ornament. 

 Its chief value, however, was from its adaptation to the transport by sea of new and 

 rare plants. All Fortune's new discoveries were sent from China in this way, and 

 the Tea plant was forwarded thus to be domesticated in India. Consignments are 

 continually arriving from all parts of the world in England and America in Wardian 

 cases, which exclude the sea air and spray, and thus enable the Captain to carry the 

 package on deck, so that plenty of light can be admitted. 



The Aquarium is an adaptation of Ward's principle of compensation to the 

 ing inland of sea animals, fishes, shells, &c., in a healthy condition. The
