along the bluff in the form of a narrow bay one and a half miles 
in length, the so-called Quiver Lake (Plate XIII.), open to the 
river below, and receiving Quiver Creek at its upper end. This 
creek (Plate XVII.), largely formed by the drainage of a sandy 
tract to the east and north, empties into the broad and shallow 
head of the lake through a muddy and weedy flat. Quiver Lake, 
like the river below, has a sandy bank and margin on the east, 
and a mud bank on the west. The natural drainage of the 
sand escapes in large quantities along the eastern side of this 
lake, keeping the shore constantly saturated with cold water, to 
a greater or less width according to the level of the lake, and 
modifying greatly, when the river is low, the character of the 
waters of the lake itself. A broad bay of this Quiver Lake 
extending to the west from near its middle, forms what is 
known as Dogfish Lake (Plate XIV.), with shores of black 
alluvial earth all around. 
The other waters of the vicinity included in the system of 
Station operations are Thompson’s Lake (Plate XVI.), a shallow 
body of water about five miles long by one mile wide, lying in 
the bottoms near the western bluff; Flag Lake (Plate XV.), a 
shallow muddy pond or, more correctly, a marsh, about three 
miles in length, largely overgrown in summer with the club- 
rush, water-lily, and arrow-head; and Phelps Lake, a small 
pond of dead water, three fourths of a mile in length, with 
almost no vegetation, in the midst of a densely wooded bottom¬ 
land. 
The field headquarters of the Station party, the summer 
location of the laboratory boat, was at the foot of Quiver Lake, 
against the sandy eastern bank (Plate II.). The top of the 
bluff is here wooded at the edge and for a variable distance 
back with oak and hickory and ash and other common hard¬ 
wood upland trees. Cottonwoods, walnuts, locusts, coffee-trees, 
elms, and pecans of a considerable size, extending in a rather 
ragged line, offer a very welcome shade at the foot of the bluff 
at about high-water mark. An abundant supply of very pure 
and delightfully cool water is easily reached everywhere, either 
in running springs or by driving down an iron pipe for a few 
feet in the sand and screwing on a common cistern pump.

hank of Quiver Lake and beside the river between that lake
