Other trials at this place would probably show that currents 
at different depths sometimes go in different directions. An 
opposite current at the surface and near the bottom has been 
observed in the Black Channel by Ralph Scherz. 
RAPID CURRENTS. 
Several of the examples cited above show currents of much 
more than average velocity. Since the opening has been nar- 
rowed by jetties the current is at times so strong as to make it 
difficult for tugs to pull vessels into or out of the bay. 
The rapidity with which sewage may be carried out of the 
bay under favorable conditions is shown by bottle No. 67, thrown 
off the end of the dock of the Sandusky Lumber and Box com-: 
pany, December 5 at stinset, and found at sunrise December 6, 
by Mr. Ritter close to the south side of his light station at the 
entrance to the bay. North and northeast winds with maximum 
velocity of 22 miles had blown since early morning of the pre- 
ceding day raising the level of the bay, but the wind became light 
the afternoon the bottle was thrown in and changed to south-- 
west soon after, blowing light from the southwest or south all 
night, and giving opportunity for the flood to subside. 
Brisk southwest winds often lower the water in the bay as 
much as two feet, and brisk northeast winds raise it that much 
above the usual level. Assuming the average depth of the entire: 
bay to be nine feet, a southwest wind will reduce it to seven feet. 
A northeast wind following this may raise the level to eleven feet 
and so bring into the bay from the lake more than half as much 
water as the bay contained a few hours before. 
THE METEOR OF SEPTEMBER 15, 1902. 
E. L. MOSELEY. 
( Abstract. ) 
At about 5:40 a. m., Washington time, a meteor entered the 
earth’s atmosphere, probably over West Virginia, and traveled 
north at least three hundred miles, leaving behind a luminous 
train that remained visible until it faded out in the light of dawn. 
Over Ohio its elevation was very great, and most observers heard 
no sound, but at London, Ontario, the detonations and reports 
were very loud and sounded like distant cannon. 
I am still collecting data regarding it and would be thankful 
for a communication from any one who had a good view of it, 
and especially for a careful estimate of its minimum zenith dis-- 
tance.
