114 The Ancient Canals in the Delhi Territory. [Marcn, 
natural channel to. Jhydart, thence by a new cut into the Putralla, 
which it follows to its junction with the Sémbe, where Lieut. Buanz 
projected a dam of masonry, but was deterred from its execution by 
the heavy floods of 1820: the earthen dam then required was in extent 
500 feet, now it has extended to a serious work of 1200 feet; the ex- 
tension is attended with the advantage of the floods attaining less height, 
as none have reached since within three feet of the height he noted.— 
From this point an entirely new channel connected this work with the. 
old line of canal near Burya, whence its bed was simply cleared or 
restored as far as Delhi ; in the vicinity of which a number of old bridges 
were repaired and some new ones built, besides which the only other 
works done were the formation of a new escape dam at Kanjniin to- 
wards the head of the canal, and the restoration of anoldone near Bowana, 
for the tail of it; both works of vital importance, though still insufficient 
from want of a more centrical escape (as at Karnal), to pass off the 
heavy land floods from the north of Karnal, which are added to those of 
the canal in the rains: the old channel by Budakhera presents a suitable 
site for such a work. On Lieut. Buanu’s unexpected death in June, 1821, 
the canal was considered finished, and the bills rendered, amounting 
to somewhat more than half of the estimate—many works noted in 
them were not even commenced. The canal was however in fact com- 
pleted, so far as conducting the supply of water then needful was con- 
cerned. When this supply came to be increased, and that for Feroz’s 
canal to be also brought down by the same head, the canal was no 
longer efficient ; to prevent inundation, it became necessary to embank 
the canal nearly from end to end, and when the water became so deep 
as not to admit of a loaded hackery (or cart) passing through it, it 
became necessary to build bridges, so that from within a few years of 
Captain Buanr’s death, the works of the canal, suited to its present 
purposes, have been in almost constant progress, and upon an enhanced 
scale, from the canal being kept full of water during their execution ; 
for the irrigating villages had then become dependent on it for the means 
of paying their revenue. These works are only now drawing to com- 
pletion. 
Restoration of Feroz’s Canal. Main branch, Rair to Bahaderah, 1514 
miles in length ; Rhotak branch, 45 miles long ; Darbah branch, 32 miles 
long ; New Supply Head, 12 miles long. Total length, 240 miles. 
The idea of the advantages of this work appears to have presented 
itself to the mind of Captain Buanz, when employed on the Delhi canal, 
in its vicinity ; but they were first specifically brought to the considera-
