RE Bae UR REN SUN. SANDUSKY “BAY.. 
E. L. MOSELEY. 
PURPOSE OF INVESTIGATION. 
One who walks or skates much upon the bay cannot fail to 
have his attention drawn to certain places where the ice never 
forms or never becomes strong. Some of these weak spots or 
openings are probably due to the water rising from springs be- 
neath. Others, it seemed to me, might be due to currents of other 
sorts and suggested an investigation of the currents of the bay. A 
definite knowledge of the manner in which the inflowing water 
distributes itself over the bay I thought might also give a clue 
to the deposition of sand brought in from the lake and so perhaps, 
at some time in the future be of use in the planning of harbor 
improvements. The deposition now going on could not be in- 
ferred from an examination of the deposits themselves for the 
entrance to the bay is more than twice as wide as it was three 
quarters of a century ago and recently its form has been altered 
by the construction of jetties. 
In the course of a discussion at the men’s club on the water 
supply of Sandusky, a prominent citizen stated that there was “‘a 
current along the front of the city past the mouths of all the 
sewers carrying the polluted water right along toward the water- 
works crib.” This afforded another reason for trying to learn 
something of the movement of the water. 
There’s a fascination about casting a note upon the waters 
with the thought that it will return after many days. Moreover 
many a peasant’s boy and many a lone fisherman who. seldom 
receives a communication through the mails is cheered to find 
one that has drifted to him across the water. He is glad to help 
in such an investigation, expectant too of some slight reward, 
and not disappointed when it comes. So that people who question 
the sanity of a man who does anything unusual, unless it is‘cal- 
culated to put money in his pocket, may at least excuse this craze 
as a harmless diversion. 
METHOD. 
Investigation of the currents has been chiefly by means of 
drifting bottles. Each bottle contained a notice that could be 
read through the glass, calling attention to the fact that it was.
