16 MICHIGAN SURVEY, 1908. 



weeds, of which the Cow Parsnip umbels furnished excellent places for 

 collecting Syrphid flies, Cerambycid beetles and Hymenoptera. 



The fauna of this clearing consisted largely of insect? which fre- 

 quent flowers, and butterflies which fly in open places ; but a few animals 

 were found about the Light-house itself. The Chipping Sparrow bred 

 in this clearing. Fi(j. 1. 



Station II. This station included the clearing at the mouth of the 

 stream which drained Lake Benson, and which we called Benson Brook, 

 and followed the blazed trail to Sargent Lake, and on to McCargoe Cove. 

 The clearing at the beginning of the trail at Rock Harbor marks the 

 site of the former settlement called Ransom on the old maps. 



Station II, Suistation 1. Ransom Clearing and Benson Brook. The 

 clearing was occupied by scattered Small-toothed Aspens and Birches, 

 and was well sodded with grass and Red Clover. Our attention was 

 called to this locality because of the great number of Garter Snakes 

 (ThauinopMs sirtalis) which were found there. These snakes were very 

 abundant in a small area east of the mouth of the brook, in a rank 

 growth of grass and among some rails. 



The brook contained but little life, although it was carefully examined 

 near its mouth and farther back where the trail crosses the brook. 

 Only a few dead Fliysa were found, and a young fish, at the moutli of the 

 brook. 



Station II, Substation 2. Tamarack Swamp. This is a long swamp 

 which is crossed by the trail, and which contains a scattered tree 

 growth of Tamaracks, Black Spruces and Arbor Vitae, a dense shrub 

 growth of Cassandra and Labrador Tea, and a ground cover of Sphagnum 

 and Pitcher Plants. While no water was seen on the surface, it was 

 a wet swamp. 



This locality was only examined for birds and mammals. 



Station II, Substation o. Rock Ridges. This station number is given 

 to the open rock ridges which were crossed by the trail between II, 2 

 and Sargent Lake. These ridges have been burned over and are largely 

 destitute of soil and the Cladonia growth usually found on other rock 

 ridges. Small-toothed Aspens generally border these ridges which have 

 a northeasterly southwesterly direction. The heat during the middle 

 of the day is excessive. The scant vegetation which grows in some 

 crevices and depressions in the rock leaves an open area which is decided- 

 ly favorable for grasshoppers. In some places they were exceedingly 

 abundant and many ridges were examined almost solely for their grass- 

 hopper fauna. In the dry soil on one ridge an anti-lion larva was 

 found in the dust at the base of its funnel, and a .large Oarter Snake 

 was taken on another. The grasshoppers found here were Chloealtis 

 conspcrsd and abdoininalis. Circotettix vcrnicnlatiis. Mclanoplus 

 alaskanns and fasciatus. 



Station II. Substation //. McCargoe Cove. This station simply marks 

 the location of the end of the trail, and the cove where a few molluscs 

 were found. There were dead shells of Anodonta grandis footiana. 

 which were abundant at the edge of the water. Here upon the low 

 rocky shore were also found specimens of Llmnaea stagnalis. 



Station II, Sutstation 5. Forltes Lake. The examination of this 

 small lake was mainly confined to the north shore, as the south shore
