30 MICHIGAN SURVEY, 1908. 



small foot-print like pools in the outer part of the Buckbeau and sedge 

 zone. In the Cassandra zone were taken the dragonflies Enallagma ha- 

 geni, Aeschna, Leucorhinia proxiina, the grasshopper Melanoplus alas- 

 katius, and the butterfly Pyrameis carclui. From this bog were also taken 

 the Arachnids, Lacinius oliiocnue, Drasstis neglectus ■ Sind Pardosa gla- 

 cialis. ■ 



The stations at Washington Harbor were not examined in 1905 in as 

 much detail as were other localities, and the descriptions will therefore 

 be correspondinglv brief, and will be supplementary to a similar account 

 by Euthven, '06, jpp. 48-52. 



Station I, '04- Clearing at the Head of WasMngton Harhor. This 

 clearing is the property owned by the Washington Club of Duluth, Minn. 

 Much of it is sodded, pastured and under some form of cultivation. 

 These conditions were particularly favorable for grasshoppers, which 

 occur in great numbers. The following species were taken : Steno'bo- 

 thrus curtipennis, Chloealtis abdominalis, G. conspersa, Mecostethus 

 Uneatus, Catimula pellucida, and Melanoplus alaskanus. This area ap- 

 peared to be a favorable resort for migrating birds, as shown in the ac- 

 companying report by Peet. 



Station TI, '0^. Washi/n,gton Creek. This is the small trout stream 

 which flows into the head of Washington Harbor. 



Station III, '04- Trail along the Top of the Oreenstonr Range, the 

 "Desor Trail." This trail follows the road which has been opened from 

 the Club House (I, '04) to Lake Desor (VII, '04). At the western end 

 this road traverses a forest which varies considerably in its com- 

 position. In places it is dense and apparently original, but at 

 one place it has been burned and replaced by an abundant gi'owth of 

 Birch. The original forest is dense and composed of large trees, and 

 the proportion of hardwoods is surprising, since the Balsam-Spruce 

 forest is so prevalent elsewhere upon the island. The hardwoods are 

 really dominant. The forest Fig. 49, is composed of Yellow Birch, 

 Balsam, Arbor Vitae, and a few vSugar Maples, and the undergrowth of 

 Mountain Maple and Ground Hemlock. Farther out on the trail, toward 

 Lake Desor, the Maple becomes dominant and forms an almost pure 

 stand, so dense that in places there is almost no undergrowth, and the 

 forest appears quite open with a scattered ground coyer. A loose thick 

 layer of leaves and twigs covers the forest floor. In the more open 

 places the ground cover is composed of Large-flowering Raspberry, Wild 

 Sarsaparilla, Clintonia horealts, Lycopodium, mosses. Ground Cornel, and 

 the shrubs. Mountain Maple, Beaked Hazel, Round-leaved Cornel, Moun- 

 tain Ash and Red Cherry. The Yellow Birch is a large tree, with 

 a diameter of about 2 feet; White Pine is very rare, but the trees are 

 large, even about 3 feet in diameter; Arbor Vitae reaches about 2 feet. 

 A few Large-toothed Aspens, Black Oak and Black Ash were seen, the 

 Aspens about 20 inches in diameter and the Maples 10 to 15 inches. 



Red Squirrels were seen in the forest, the body of a Lynx was found 

 hanging on a tree where it had been left by a trapper, and several Toads 

 were seen. Invertebrate life Avas abundant. In an Arbor Vitae stump, 

 galleries of an ant, Caiiiponotus herculeanus whympvrl (140 A), were
