NOTES. 



Mr. S. D. Dill, of the American Museum of Natural History, New 

 York, has on his recent visit to this coast succeeded in completing 

 the great series of woods of the United States, known as the Jessup 

 Collection. This collection fills a great room, the sections being 

 taken from perfect trees of good size, and are all of the same length, 

 four feet eight inches when leveled and polished. They are so cut 

 in the upper third as to show the surfaces in horizontal, vertical and 

 tangential section. The trees of which examples were secured on 

 this trip are Arnelanchier alnifolia, Yehm Prairie, Washington, seven 

 inches in diameter; Prtimis emarghiata, shores of Lake Washing- 

 ton; Prtiniis S7ibcordata. Oregon, six inches; Manzanita, King's 

 River Canon, nine inches; Popuhis angiistifolia, Colorado; Querctts 



Jacobt,Ye\\m'?v3.\r\e; Quercus 



Quercus agrifolia, Newhall; Q 



Quercus Macdonaldi, Santa Catalina Island j Quercus Engelmamii, 

 Fall Brook; Pinus latifoiia, Santa Rita Mountains, Arizona; Se- 

 quoia semperviretLs, Santa Cruz Mountains, twelve feet; Sequoia 

 gigantea, King's River, twenty feet. Nearly all the species of 

 Quercus mentioned above are mere variations of other species al- 

 ready in the collection, but their value is not lessened by that fact. 

 The difficulty of getting together this great collection has been 

 immensely increased by the care taken to secure perfect trunks 

 without branches, and with the bark uninjured; but its value as an 



exponent of the timber resources of our country cannot be too highly 

 estimated.
