A COLONY OF ALNUS GLUTINOSA IN EASTERN MASSACHUSETTS, — 
The European Alnus glutinosa, Willd., seems to be fairly well estab- 
lished along the upper part of Whitmore Brook, West Medford, and 
about the swamps drained by it. From twenty-five to thirty speci- 
mens have been observed in this locality, varying in size from the 
shrub of a few feet to a tree thirty-five to forty feet in height. A few 
years ago this colony was much more numerous, but recently several 
of the largest trees were sacrificed in the improvement of an estate. 
No record has been found of the introduction of the species in this 
place. — C. H. Monss, Medford, Massachusetts.
