66 THE CULTIVATED EVERGREENS 



on the eastern side of the continent were in the Ellwanger 

 grounds on Mt. Hope Avenue, Rochester, New York. The 

 seeds were brought from CaHfornia by "Pony Express" in 1854 

 by Ellwanger & Barry. They raised about three thousand 

 seedlings and most of them were sold in England. Ellwanger & 

 Barry planted a small group near their office and they did re- 

 markably well. The largest individual in 1916 was seven and 

 nine-tenths feet in circumference and fifty-five feet in height. 

 The severe winter of 1916 and 1917 so injured them that two 

 years later they died and have recently been removed. If 

 they were planted out when quite small, which is probable, 

 they therefore were growing exposed to a series of winters ex- 

 tending to about sixty years. The sequoia is, therefore, not 

 to be recommended for ornamental grounds in the northeastern 

 United States. 



Taxodium. 



The bald-cypress, Taxodium distichum, which is not ever- 

 green, is a very lovely tree in cultivation and does remarkably 

 well. It is of pyramidal habit and the slender branchlets, 

 covered with light green feathery foliage, render it a charming 

 tree for parks and gardens. It is very important to plant the 

 bald-cypress in a moist, well-drained, good soil. Although this 

 species grows naturally in swamps, probably if it were tried in 

 cultivation it would be a failure. 



Arbor-vitoe. 



The common arbor-vitse. Thuja occidentalis, which in a 

 natural state extends into northern Canada, is perhaps one of 

 the hardiest coniferous evergreens and the most abundantly 

 planted. It is planted extensively as a protective hedge. Many 

 of the market-gardeners in Irondequoit, New York, use arbor- 

 vitse in hedges on the western, northwestern, and northern
