growths in especially vigorous two or three year old white pine 

 {Pinus Strohus L.) seedlings, in the nursery of the Yale Forest 

 School; but also fully formed shoots, which, judging from the 

 five leaves at their base, have clearly developed from such short 

 growth buds. 



Professor J. W. Toumey, of the Yale Forest School, states 

 that he has seen, in the vicinity of New Haven, a large tree of 

 Pinus Strohus L., which, as a result of some kind of injury, had 

 developed a considerable number of its short growths into long 

 growths. 



Pinus excelsa Wall., from which the shoot illustrated was 

 taken, is also a member of the white pine group. It is commonly 

 known as the Bhotan pine, and is a native of the Himalayas. 

 As far as the writer can ascertain, the abnormality under dis- 

 cussion has not been before recorded for this species. According 

 to Penzig,* however, the phenomenon has been noted in Pinus 

 sylvestris L. by several observers.

THE DISTRIBUTION OF MACROCYSTIS PYRIFERA 



ALONG THE AMERICAN SHORE OF THE 



STRAIT OF JUAN DE FUCA 



By George B. Rigg 



Setchell and Gardnerf report Macrocystis pyrifera as extending 

 northward "up to the Strait of Juan de Fuca" and state that 

 "It does not seem to be plentiful in Puget Sound itself." They 

 report a specimen collected by Gardner from the west coast of 

 Whidby Island. Dr. Gardner states in a letter to the writer, 

 that this was a floating specimen and that he did not find this 

 species growing on the coast of Whidby Island.
