work during the latter part of June, to continue into early 
September and I am asking a number of active amateurs to cooperate 
if they care to do so by joining me for such portion of the summer 
as they feel inclined, in the exploration and collecting. Parties 
of two or three will be made up for trips of two or three days to 
selected areas and each party will be asked to collect an extra 
set of specimens which the Gray Herbarium may have in return for 
the facilities supplied and in return for determinations and labels 
so far as these are wished. The region from Digby and Yarmouth 
around the southern side of Nova Scotia nearly to Cape Canso con¬ 
sists of a peculiar siliceous rock which is classified by the 
geologists as the Avalonian formation, the peculiar rock formation 
which is otherwise known only in southeastern Newfoundland, the 
region where so many strange affinities have been found in that 
colony. Examination of the detailed geological maps shows this 
section to contain at least five thousand (5000) ponds and nearly 
as many if not more bogs and barrens, the habitats where these 
isolated plants chiefly occur, and to have plenty of carriage roads 
and several railroads, so that a summer spent there should be 
most productive and one of comparative simple botanizing. I 
sincerely hope that all who receive this announcement will feel 
like cooperating for the whole or part of the summer in the 
enterprise. The steamboat fare from boston to Yarmouth is $8.64. 
Those who prefer rail travel can go to St. John, New Brunswick 
and cross by ferry to Digby. Fords or other light cars would 
be very useful.
