ZOOLOGICAL GARDENS.

upper jaw. As these are persistent structural characters, 
it is erroneous to speak of any of the crocodiles of the 
Old World as Alligators which are essentially distinctive 
of America or the New World. The Gavials are confined 
to India proper, Borneo and the north of Australia. They 
are easily distinguished from either crocodiles or alligators 
by their long snouts. 
But, although this lake abounds in crocodiles it teems 
with fish, as it is annually stocked with fry. The most 
abundant fish in the lake are the Labeo rohiia , the 
Ruee; Labeo calbasu y the Kalb an s; Catla buchanani , 
the Catla ; Notopterus kapirat , the Chital; but the most 
prevalent of all is Mugil corsula, the floating Vang?tr } one 
of the Mullets, a surface-swimmer. 
A considerable revenue is derived from rod-fishing, and 
there are some enthusiastic and persistent lovers of the 
piscatorial art, and none more so than an old Muhammadan 
woman. Ground-bait is largely used in fishing and is 
made up of highly aromatic substances introduced into 
a split bamboo, which is taken out for some distance and 
fixed in deep water. A delicate wand is left project¬ 
ing above water, and as it vibrates, the presence of fish 
is indicated, and the line is cast over the spot. The reg¬ 
ular fishers generally go to the expense of erecting a 
small wooden platform, a little distance out from the 
bank. 
The Gate at this extremity of the Gardens exists solely 
for the entrance of stores and other materials. Across the 
public road outside, and bn the banks of Tollah’s Nullah 
is the Pumping Engine in connection with the chain of 
lakes and tanks in the Gardens, and by means of which 
they are kept at an uniform level.
