84 Evermann d' Clark. — Fletcher Lake, Indiana. 



before the net and interfered seriously with seining operations. 

 Various algae, among which were Chara, Spirogi/ra and Mcsocarjms, 

 were quite abundant; on the Chara grew considerable attached 

 Rividaria. 



The water of Fletcher Lake was at tlie time of our visit a 

 clear lively green like that of Lake Maxinkuckee, and without 

 the yellowish cast characteristic of Eagle Lake. No plankton 

 was collected. 



A number of soundings and bottom temperatures were 

 recorded. The only vessels of any kind on the lake were about 

 a dozen flat-bottomed boats, excellent for cruising aliout near 

 shore, but very difficult to row straight and hard to keep in 

 place, especially during a wind, such as prevailed at the time. 

 However, it is l)elieved that the soundings taken are sufficient 

 to determine the maximum depth and general topography of 

 the lake bottom. 



Several lines of soundings were run and temperatures taken 

 as follows: 



1. A line on the long axis and in the center of the lake from 



east to west. Depths in feet— 22.5, 35, 3L5, 33.5, 34, 

 16.5. Bottom temperatures in fahrenheit degrees: 51°, 

 47.1°, 47.9°, 48.5°, 47°, 64.4°. Temperature of air, 77°. 



2. A line on the long axis, from east to west, taking a sounding 



at every 10 oar-strokes. Each stroke carried the l)oat 

 about 5 feet, thus puttii:»g the soundings at intervals of 

 about 50 feet. Depths in feet— 5, 22, 34, 34, 34, 32, 32, 

 34, 32, 32, 34, 40, 41, 40, 33, 28, 28, 30, 28, 26, 32, 38, 

 40, 40, 37, 30, 28, 15, 5. 



3. A line ffuiu south to iiortli about 200 feet east of tbc west 



end. Depths in feet— 15, 11), 24, 34, 38, 38, 33, 30, 21, 

 16, 6. 



4. A line from north to south beginning about 200 feet east of 



north end of line 3, ami ending about oOO feet east of 

 soutli end of line 3. Depths— 5, 14, 19, 24, 28, 28, 28, 

 28, 29, 29, 2S, 30, 31, 35, 34, 31, 21, 14. 



5. A line from the cami) site on south shore to a point on shore 



400 feet east of the brick house. Depths— 8, 19, 21, 27, 

 , ^0, 32, 30, 26, 20, 20, 17, 12, 2.
