HARDY CONIFERS FOR PRIVATE ESTATES. 93 



distance outside the latitudes of their natural geographical distribu- 

 tion, and very few trees will exceed those limits very far unless the 

 isothermal and atmospheric conditions are relatively maintained. 

 Southern Indiana is the northern natural limit of the Bald Cypress 

 but it does remarkably well in many places in the Northeastern 

 States. It should always be planted in moist soil. The light green 

 foliage looks very attractive. 



Our native Arborvitae {Thuya occidentalu) is a very useful and 

 accommodating conifer and it does remarkably well in a variety 

 of different conditions, and stands the sweep of cold winds well. 

 In a natural state it generally has a stiff outline. The numerous 

 varieties of this in cultivation are excellent garden plants, particu- 

 larly in formal gardening. 



The Canoe Cedar or Western Arborvitae (T. plicata) is a rapid 

 growing tree with a much thinner habit than our native one, and 

 seems to stand the cold well at Rochester. It is very ornamental 

 and promising with us. 



The Chinese Arborntae {Thin/a orieutalis) is a beautiful species; 

 it has a bushy conical habit, and the foliage is bright olive green. 

 When protected by the lay of the land, or otherwise, it does well at 

 Rochester. 



The Japanese Arborvitae (T. JapoJiica) is hardier than the 

 Chinese species. There are no large plants at Rochester, but there 

 is a good example at Wellesley about 30 feet in height. 



The White Cedar {Chamaeci/paris sphaewidea), whilst it appears 

 to be hardy enough with us, is not of much ornamental merit. 



The Yellow Cedar (C. Xutkaten.ns) is a beautiful and choice 

 species, with a bushy conical outline. The deep rich bluish green 

 foliage on the branchlets, which have the appearance of folding 

 together in layers, gives it a most attractive appearance. Our 

 plants suffered no injury during the winter of 1903-1904. 



The Japanese Retinisporas, which are noAV placed botanically 

 in the genus Chamaec^iDaris are quite extensively planted. The 

 two species Chamaecijpari.s obtusa and C. pisifem. and their numer- 

 ous varieties, which have been mostly produced and perpetuated 

 from seedling plants in their young or juvenile state, are very pretty 

 attractive garden plants wherever conditions happen to suit them. 

 As a general rule they are short-lived in the Northeastern States.
