areas being in a more advanced or more retrograde stage of physiographic and 
edaphic development. Later the low heaths appear, some growing only when 
sheltered by some projecting slab of granite. The pioneer heaths are Vaccinium 
pennsylvanicum var. angustifolium, V. uliginosum , V. Vitis-Idaea , and the cush- 
ioned Diapensia lapponica. Of less frequency are Ledum latifolium, Arctostaphy - 
los alpina, Rhododendron lapponicum , Cassiope hypnoides, Loiseleuria procumhens , 
and Phyllodoce caerulea ( Bryanthus taxifolius ) . ’ ’ 
The fell-fields of the Mt. Washington massif are described at length and 
illustrated by a number of good pictures, but the mosses and lichens are men- 
tioned only in a rather general way, the seed plants receiving the more detailed 
treatment.

SULLIVANT MOSS SOCIETY NOTES 
Members of the Sullivant Moss Society will be sorry to learn of the death 
on June 8th last, of Rev. C. H Waddell of Grey Abbey, Ireland, who had been a 
member of the Society since 1907. A short note from Mrs. Waddell states that 
her husband had just returned from church when he was stricken without pre- 
vious illness. The letter states that Mr. Waddell’s botanical collections are 
to be divided: the mosses going to the Royal College of Science at Dublin, and 
the flowering plants and lichens to Queen’s University, Belfast. 
Since the publication of the July Bryologist, Mr. H. Sasaoka, whose ad- 
dress is 30, Tsukioka, Kaminiikawa, Toyama-ken, Japan, has joined the So- 
ciety.
