tances from the Lake Superior shoal. Twelve large examples of long- 

 nosed dace, a little over three inches in length, were caught in a de- 

 pression of the creek bottom, where the water is about two feet deep, 

 just above the stream mouth. This very small and restricted region 

 is the only place in the whole area studied, where any but very small 

 long-nosed dace were taken. These large ones from Station 21 were 

 eating black-fly larvae, which made up all of the material in the in- 

 testines of four of the dace opened. The other species from this station, 

 listed above, were scarce. The burbot was caught in the small fyke net 

 set across the creek just above its mouth so as to catch entering fish. 

 It is possible that burbots visit the creek at night for food. 



Cranberry Creek is a short stream which cuts through the sand ridge 

 along the Lake Superior beach a short distance east of Vermilion 

 (Plate XI VB). On the beach it spreads out into a long, shallow pond 

 (Station 31, Plate XVA). The part of the creek through the sand 

 ridge (Station 30) was the only part examined. Here it runs some two 

 hundred feet below a small road bridge, winding about making pools 

 and narrows ; the former are as deep as three feet and as wide as fifteen 

 feet, while at the narrows the creek is constricted to two or three feet 

 •and is but a few inches deep. The water is clear but slightly stained 

 brown; it is swift, and moderate in temperature (68° F. at times when 

 the principal collections were made). The bottom is of clean dune 

 :sand except in pools where much organic debris has collected. The 

 banks are high, with scant vegetation, and are well-lighted. The 

 following species of fish were taken in Cranberry Creek: brook trout, 

 iblack-nosed dace, Leuciscus neogaeus, horned dace, common sucker, and 

 iDrook stickleback. 



The small, deep pools with overhanging banks harbored a number 

 of small brook trout, but this was the only species well represented; 

 only a few of each of the others listed being found. 



Wetherhog Creek is a short stream running from below a dam at the 

 €nd of Wetherhog Lake and expanding in a beach pond. The creek is 

 wide and very shallow and concealed by bushes for much of its course. 

 Fish were scarce in it, and few little perch and some Iowa darters 

 were the only ones taken in many hauls. 



Shelldrake Lake. 



The lake that lies in the course of the Shelldrake River some two 

 miles southeast of Vermilion (map Fig. 3 and Plate XXV A) is in 

 general similar to the larger of the marsh lakes just described. It is 

 perhaps a little over a half mile in length by a quarter of a mile in 

 ^^ddth. An extensive shoal is present and apparenth^ a large deep water
