pioU-cted. A number of the more rare trees and slirubs, siu-h as 

 Arauca.'ia 'irasiliensis, which had stood out eight years, A Cunning- 

 hainfj, Pinus inslgnis, P. palustris, P. GirardJa?ia, P. canadensis, etc., 

 .vere killed during the winter of 1837-8, and a number of others, 

 which were severely injured, are now recovering. Mr. Pratt, the head 

 gaidener, did not begin to prune the trees which were injured till the 

 rising of the sap showed the extent of the injury that they had re- 

 ceived. After waiting till the middle uf summer, it was found that the 

 laurustinus, sweet bay, Chinese privet, and various other shrubs, were 

 alive to the height of from 3 ft. to 5 ft., and after the dead wood was 

 cut out, the plants soon became covered with young shoots and 

 foliage. 



The Walks are so laid out and planted as to be sheltered or border- 

 ed by evergreens, for the sake of their lively appearance during winter. 

 They are also so contrived as to be shaded from the sun by deciduous 

 trees during summer ; while these trees being naked during winter, ad- 

 mit the sun at that season to dry the grounds. The walks are laid out 

 in different directions, in order that, from whatever point the wind may 

 blow, at least one walk will be sheltered from it. The greater num- 

 ber are in the direction of north and south, because walks in that di- 

 rection are best exposed to the sun in the winter season, which is the 

 period of the year in which the proprietor chiefly resides here. It is 

 always desirable, in a small place, that all tlie walks should be conceal- 

 ed from the windows, except that immediately under the eye, and that, 

 in walking through the grounds, no path should be seen except the one 

 walked on, and that (except in the case of a straight avenue) only for 

 a moderate distance. These rules (derived from the principle of va- 

 riety and intricacy) have been carefully attended to by M;. Harrison, 

 and hence the walk from a to b, in the plan, Fig. 13, in pp. 510, ill, is 

 concealed by raising the turf on the side next the house uighor ti.an on 

 the opposite side, while that from c to d is concealed by tho bushes and 

 trees at c, and more especially by a large rhododendron rt .;<?. The 

 walk fg h is concealed from the walk i, partly by a swell ia 'Jio surface 

 of the turf on the side next i, but chiefly by the busheo which are 

 scattered along its margin. At g, there is a clump which prevents any 

 one on the walk i from seeing the line g f, and any one on the walk g
