This little trip of two weeks’ duration was made especially in 
search of dragonflies along the line of the Algoma Central Rail¬ 
road north of Sault Ste. Marie, Ontario. Every effort was made 
to collect the greatest possible number of specimens and species 
in this group, and the other records of animals and of plants 
which follow are based upon the most desultory collecting. 
Those who have studied these miscellaneous collections have 
furnished me with notes which are published in this paper over 
the authors’ names. 
The Algoma Central Railroad is one of the Clurg enterprises. 
Aimed across a wilderness at the distant Hudson Bay, it was to 
be the highway over which the golden fleece should be brought 
to the Soo. The power of the rapids of the St. Marys River, the 
mines and forests of the Algoma District, a railroad route to 
Hudson Bay, homes for settlers, these were the things which the 
creative imagination of a man saw as material for the building of 
a great and flourishing empire from which he and his associates 
should receive wealth hitherto undreamed of. But the workmen 
came down from the mountains for their long due pay and troops 
protected the officers of the several companies. The Algoma 
Central has been built for only 70 miles. These 70 miles are, 
however, well constructed and a trestle at Bellevue is said to be 
the highest and longest wooden structure of this kind in the 
world. 
At once after leaving the Soo the road passes into mountains 
which are uninterrupted from that point to the inland terminus. 
Cuts through solid rock reveal beautiful folds of the pink and 
dark green layers of gneiss or the more uniform black,gray or
