PROCEEDINGS OF THE
5. The following from Commander W. Balfour, T.N.
‘ f The Chart of the Indus’ Rise and Fall foi ten yeais, sent to the
Geo-rapliical Society by Government, was constructed from the daily
reo-ister which has been kept at Kotree since the day I originated it in
Igh. I had the books containing this register in my hands shortly
before leaving Kotree last August. They are now in' the hands of air.
W. Hughes, Engineer, who has kept the registry since the date
mentioned. * He is at present at Kotree, temporarily in the employ
ef the Indus Flotilla Company, and is perfectly competent; and I
am sure will gladly give you any information in his power respecting
the registry. The chart you have is not the only one. There
were, I think, three others at Kotree on a larger scale, and for seven
years on each sheet. I saw that, putting so many years on one
sheet, would have the effect you mention, of so running the lines
one into another, as to render it difficult to trace them. But the
object was to supply Sir George Clerk with what he wanted, viz., a
chart for a decennial period. I always intended to have had this, sup
plemented by a copy of the daily register, and had I remained at
Kotree, it would ere this have been forwarded to Government. I should
mention, that a register of the rise and fall of the Mooltan river was
kept by the Flotilla Officer at that station, and transmitted weekly to
Kotree.. The records of the Flotilla are to come to Bombay, and it
will be found amongst them. Last inundation, I caused soundings Measurements of the depth of a body of water. to*
he regularly taken alongside the Hyderabad, to determine the rate of
silt along the bank. The record of these observations, signed by Mr.
McClaran, will be found as above.”
The business of the Meeting having been brought to a termination,
Mr. Burgess read his Paper, “ Remarks on the Bombay Tidal Observa
tions for 1861.” At the conclusion of wffiich Lieutenant Fergusson
spoke to the following effect :—>1 beg to vote the thanks of this
Meeting to Mr. Burgess, for the interesting paper he has read, as it
shows that he must have taken much pains to calculate and. illustrate
tne \ ai io m particulars and details connected with the subject of tides;
hut at the same time there are certain points on which he has touched,
on which I wish to make a few passing remarks. In the first instance
I beg to state, that the formula for computing the tidal range and time
of hi b h water given in the Observatory Volume for 1847 was, I have
given to understand, by Professor Orlebar, of the Elphinstone
