MR. C. CROSSLAND’S COLLECTION 
A collection of mosses has recently been presented to the 
Halifax Museums Committee by Mr. Charles Crossland, and de- 
posited in the botany room at the museum. They are from 
Mr. Crossland’s Moss Herbarium, but confined solely to speci- 
mens gathered within the Parish of Halifax, mostly during the 
last 25 years. They represent about 150 species and varieties, 
but there are over 400 separate packets in the collection, stored 
in four suitable cardboard boxes, and all scientifically arranged 
and named. Box No. I contains the Bog or Peat mosses, 
called also pack-mosses, a group technically known as Sphag- 
naceae, a class of mosses which grow only in wet places on 
moorlands or on other swampy, waste ground. This com- 
prises a fairly complete set of the bog-mosses recorded for the 
Halifax district, and include specimens gathered on Wads- 
worth, Stansfield, Erringden, Norland, Sowerby, Saltonstall, 
Ogden, and other local moors. They are classed according to 
Dr. Warnstorf’s ‘ European Sphagnacee,’ a reprint of a trans- 
lation of which from the Journal of Botany, 1900, accompanies 
the mosses. Boxes 2, 3, and 4 contain the ordinary mosses to
