The Pinetum. The plants in the Pinetum have not before passed 
through the winter in better condition than they have this year. Even 
most of the species about which we are always more or less concerned 
are now in good condition. The most injured species is the short- 
leaved Pine of the southern states, Pinus echinata. This is a widely 
distributed and extremely valuable timber tree, ranging from Long 
Island and Staten Island, New York, to Florida and westward to Texas, 
Oklahoma, Arkansas and Missouri, being the principal timber Pine west 
of the Mississippi River. The largest plants in the Arboretum have been 
growing here since 1879 and were raised from seeds gathered in Mis- 
souri. The leaves have always sulfered and are sometimes entirely 
killed, the trees producing a new crop, or the ends are killed as they 
have been during the past winter. The trees are poor and thin, and 
probably will never be of much value in New England for ornament 
or timber. The other conifer which has suffered during the winter is 
Tsuga heterophylla, one of the largest and most beautiful conifers of 
our northwest coast where it ranges from Alaska to Washington and 
California, and eastward to the western base of the Rocky Mountains 
of Idaho. The coast tree has often been planted in Europe with great 
success but it has not proved hardy in New England. We have grown, 
however, in a sheltered position on Hemlock Hill since 1898 plants 
gathered in Idaho which have generally grown well but during the 
past winter the leaves have been badly browned. Among other 
conifers of doubtful hardiness are the Japanese Cryptomeria japonica, 
Picea Breweriana, and Libocedrus decurrens. The Cryptomeria is one 
of the great trees of the world and the largest trees planted by man
