sloping in toward the center of Cove. Depth is 2 feet; marked by 

 tree on peninsula. 



Station V is one of the deepest parts of the Cove, 5^ feet 

 deep. 'The bottom is covered with a deep, soft layer of sandy loam 

 on which grows ^n abundance of vegetation, chiefly Myriophyllum 

 and Ceratopyllum which grows so rapidly that by August 25th it 

 is impossible to row a small boat through the Cove. These forms 

 first start submerged and later cover the entire surface. This 

 station being located in the center of the Cove is noticeably aiHiected 

 by wind and currents. In early summer, before the vegetation 

 has become too abundant, the water is clear. 



Station VI is south-east of Station I on the same side of Cove. 

 The bottom is covered with decomposed plants making a mucky 

 covering over sand. Underbrush covers the shore, back of which 

 is a small wood which furnishes shade to the shore at this station. 

 It is i^ feet deep; marked by dead tree on bank. 



Station VII is located about 10 feet south of Laboratory 

 Point in a swampy region, the water being i^ feet deep. The 

 bottom is composed of sand covered with muck. The shade is 

 sparse. 



Station VIII is midway between Laboratory Point and the 

 end of the peninsula on the south, at the opening of the Cove into 

 Sandusky Bay. This is the deepest part of the Cove, 6J2 feet. 

 There is abundant vegetation, as at Station V. The bottom is 

 mucky and the wave action quite pronounced. No shade. 



Station IX is near the shore, at the extreme east end of the 

 narrow peninsula en the south. The water is shallow at this point 

 being onl)^ i 1-6 feet deep. The bottom is sand covered with scant 

 vegetation. The peninsula ends at this point as a sand bar. 



All observations and collecting was done by the aid of a big, 

 heavy, flat bottomed row boat which was 12 feet long and 3 feet 

 wide, having very low sides. It had to be quite large in order to 

 carry the necessary equipment, to give ample room for taking the 

 readings, and for preparing collected material for safe transportation 

 to the laboratory. The heavier the boat the. less chance for drifting 

 from the point of operation. Having a fiat bottom there was very 

 little chance of rocking and it presented a plain surface on which 

 could be placed bottles, jars, etc. Having low sides, 5 inches above 

 the water surface, it facilitated the work of handling the nets, taking 

 temperature readings and making observations along the bottom.
