From the Ist to the 16th of September inclusive, the moon's 
southing occurred within the hours of the readings for high and 
low water. Of these days, on the 1st and 8d the flood arrived 
within ¢wo hours after the passage of the moon. On the 2d, 4th, 
6th and 7th from 5 to 11 hours afterwards. On the 8th, 9th, 
10th, 12th, 13th, 14th, 15th and 16th from 5$ to 114 hours be 
fore southing, but on the 9th and 13th there were two maxima 
3 to 5$ hours after. From the 12th to the 15th inclusive, four 
days, the weather was continually calm at the place of observa: 
tion. The variation of level during those days was small, the 
mean being four inches, the least 2, and the greatest 54 in. This 
was the most favorable opportunity for the appearance of a lunar 
tide. The period of conjunction passed on the 7th, and conse 
quently the calm weather all came within the first quarter. 
Neither on those days or during the most quiet periods embraced 
in Mr. Underwood’s register, do I discover evidences of a flux 
and reflux that I can connect with the moon’s motions. 
Perhaps more perfect and prolonged observations might dis- 
close such evidence. No station can be found better calculated 
to test the question fairly, provided simultaneous observations 
are made at the mouth of the bay. It is to be hoped the atten: 
tion which the officers of the United States Topographical Corps 
are now giving to the subject of lake fluctuations will lead to 
such observations.*
