MAY 1764 . 
11 
The nth. mostly fair Weather, having only one slight squall from y e Southward. 
This Forenoon passed by Amboa, 1 which lies on y e South side of the River in y e long 
reach between Cutchoa and C ulna. 2 * * * I observe that this Place is remarked in some of 
y e old maps of Bengali & therefore imagine that it must once have been a flourishing 
Village; however at present it contains only a few poor Huts Fay at Beldanga* 
this Night. 
The 12th. fair Weather all day, the Evening .heavy & threatning. At 8 in 5 
the Morning entered the Jelenghee River + The Cossimbazaar River 6 at its conflux 
with the Jelenghee appears to be very narrow : I judge it cannot at this Season be 
above 50 yards over. The People inform me that it is now navigable for middle- 
sized Boats. 
In the Evening at Hautnagore measured a Base & found the breadth of the 
River (Jelenghee) to be 150 yards now & 270 in the Rainy Season ; its depth 13 foot 
in the deepest Place. It appears by the Banks that it will rise 13 foot more with 
the Rains. 
The 13th. very fine Weather all day. Wind from the South. The River grows 
very shallow, & so crooked that though we have gone 22 miles thro’ y e River this 
Day, we have scarce advanced 10 in a right Fine. Fay at Teegaree or Negarin this 
Night. At Sunset found y e variation of the Needle to be 3°-3' Fast 1 ? by an Ampli- 
tude. 6 
The 14th. the Forenoon fair ; in y e afternoon a hard Squall from the Westward 
with much Rain, Thunder, & Fightning. By reason of y e bad Weather, we have 
proceeded only 16 miles this Day. At Notydungah, where we lie this Night, the 
River is only 2 Cubits deep. 
The r.Sth. very squally Weather, & much Rain. This, together with y e 6 
shallowness & intricacy of the Channells of the River, retards our Passage much. 
In some Places the Channell is not five yards over. At Paunchdaddah measured 
the breadth & depth of the River, & likewise took y e altitude of the Banks. The 
breadth is now 200 yards ; the depth nowhere more than 5 Cubits. By the Banks 
the River will rise by the Rains 26 feet more. By this, & the former Experiment 
made at Hautnagore (the 12th.), it appears that the River swells much more in the 
neighbourhood of the great River (Ganges) than in Places remote from it, & that 
the difference is so much as 12 or 13 foot in y e distance of qt miles. 
1 Amboa. Marked as a considerable village on Van den Broucke’s map of 1660 under the name Ambowa. It is 
not shown in the modern ‘Atlas of India.’ 
2 Kalna, a town of considerable importance on the right bank of the Bhagirathi. A large fort existed here in 
Muhammadan times. 
2 Haldanga. A ferry a short distance below Nadiya. 
+ The Jalangi, one of the three 1 Nadiya Rivers,’ the other two being the Bhagirathi and the Matabhanga. It 
flows from Jalangi village on the Padma (Padda) or lower Ganges along an exceedingly tortuous course to the south- 
west to Nadia, where it joins the Bhagirathi. The united rivers form the Hugli. In the hot weather it is little more 
than a string of marshes connected by shoals and is fordable at many points. (Imp. Gaz., Vol. xiv, p. 16). 
6 The Bhagirathi. 
8 This variation of the compass is quite abnormal (see p. 121). At most of the places wheie it was determined 
by Rennell it varied within o° and 2" West. It is now about i° 30' East, on the average.
