288 THE BOTANISTS OF PHILADELrHIA.

 boring plantations, and in good, strong, well-drained soiL 

 No special care has been given to the plants, and those 

 which remain are standing in a thick sod of grass. 



A writer in Garden and Forest, November 1, 1893, (VI : 

 458), says of the pinetum : " Before describing the trees that 

 are left standing, it will be well to explain that all the 

 species and varieties of Cupressus have disappeared entirely, 

 as have most of the South European, Indian, Mexic-an, 

 and South American species and their varieties. With a 

 few exceptions, all the conifers of the Pacific States of North 

 America have succumbed to our cold winters or moist 

 summers. Few of the pines which were planted twenty 

 years ago are left. The European Pinus sylvestris, P. 

 Austriaca and P. Laricio are alive, but have passed the 

 period of their greatest beauty and show signs of premature 

 decay. Pinus Strobus nivea has grown into a compact and 

 handsome plant, but the other forms of the white-pine have 

 disappeared, owing, perhaps, to the attacks of a new enemy, 

 which, Mr. Hoopes informs me, has destroyed many of the 

 white-pines in West Chester. P. monticola, its western 

 representative, has grown into a tall, thin specimen, some 

 twenty feet high, showing the thin, lanky habit of this tree 

 in cultivation, which is, however, one of the hardiest of the 

 western pines here at the east, although as an ornamental 

 tree it cannot be compared with the native white-pine. Of 

 the other white-pines, the sugar-pine, P. Lamhertiana, of 

 California, and P. excelsa, of the Himalayas have disap- 

 peared, but the collection still boasts, in perfect health 

 and beauty, one of the best specimens of P. Pence, of 

 southeastern Europe, which can be found in cultivation — a
