May, 1907.] .4 Collecting i rip North of Sault Ste. Marie. 
Collections were made at the following points along the 
Algoma Central. On July 29th and 30th, a little collecting was 
done about the Soo, and on July 30th I arrived at Hey den, about 
thirteen miles from the Soo. While at Heyden I lived with Mr. 
William Marshall who is operating a shingle mill there. The 
afternoon of July 30th was spent along Mud Lake, near the shore 
of which Hevden is situated .along a similar lake just above Mud 
Lake, and along the small marshy stream connecting the two 
lakes. July 31st a wagon trail west of Heyden was followed for 
about two miles to a beaver dam on a small stream; this stream 
was followed to its mouth in Root River, and Root River was 
followed down stream to where it is crossed by the railroad. 
August 2d was spent along Root River below the point where 
the railroad crosses it and at the stony ripple just above this 
point. On August 3d and 4th Stony Lake was visited. This is 
a beautiful body of water lying in the hills high above and to the 
east of Mud Lake, into which it discharges its overflow. I was 
told at Heyden that the name was local as the lake does not 
appear on any maps of the district. The precipitous shores of 
this appropriately named lake made exploration difficult and 
almost fruitless or dragonfly less. The greater portion of the 
two days was spent about the lower, pond-like, end of the lake, 
where a dam, constructed by Perry for getting out pine, still 
holds the lake above its natural level. About this portion of the 
lake dragonflies fairly swarmed—usually out of reach of the 
collector. August 1st was spent along the Goulais River above 
Searchmont, and at the mouth of Achigan Brook. August 5th 
was spent along the Algoma Central as far as the inland terminus. 
Rain and cloudy weather prevailed during the entire day and no 
dragonflies were collected. August 6th was spent along Achigan 
Brook for several miles above Searchmont. Achigan Brook 
flows from Spruce Lake. It is known also as Spruce Creek and 
Little Goulais. I have never followed a more beautiful stream 
than this. Long, precipitous rapids, where great broken masses 
of rock impede the water, flinging it into a myriad of rainbows, 
alternate with serene slow-flowing pools, now broad, now nar¬ 
row, in sunshine and shade. On August 7th I went on the tote- 
road to the third dam on Perry Brook, several miles from 
Searchmont ,and followed this stream till its clear waters mingled 
with the yellowish waters of the swift flowing Goulais. Along 
Perry Brook are great exposures of the clay mentioned above 
and of sand banks. August 8th was again spent along Achigan 
Brook several miles above Searchmont. On August 9th I 
walked south on the railroad three or four miles to where the 
railroad crosses Dam Creek. Dam Creek was explored for 
about a mile above the railroad and below the railroad to its 
mouth in the Goulais River. On my return trip home I stopped
