Sie Peoby Cautley's "Report on the (ranges Canal Works" (3 Vols. Text, with an Atlas of
76 plans and maps), printed in 1860 for private distribution only, contains a number of places, the
relative height of which he had occasion to determine by careful levellings along the various lines
of the Ganges Canal. His zero-point was the Maiapur regulator, near Hardvar, at the head of the
Canal, and the spot most nearly coinciding with our own determinations is the Rurki bridge. From
a private communication, kindly received from Sir Proby Cautley himself, the bed-flooring of the
Rurki bridge may be assumed as 43 feet below the entrance of the Rurki Thomason College. The
absolute height of this college, according to our observations3, being 997 ft., that of the Rurki bridge
consequently is 954 ft., viz. (997 ft. — 43 ft. — 954 ft.) The difference of level between the Maiapur
regulator and the Rurki bridge is 61 ft.; therefore, the absolute height of Maiapur = zero-point,
1,015 ft. The zero-point thus fixed, the heights can be given in absolute values for all the levels
contained in plates X., XL, and XII. of Sir Proby Cautley's Atlas.
We present, however, the principal places only, the difference of height between the intermediate,
or secondary stations being extremely small.
