^[Unagek (Island) Lake. — ]\[ean of seventeen good measurements 
1,584 feet. The only previous measurement of this charming lake is 
my own of last year, 1,510 feet, concerning which remarks are made 
below. I made this lake by direct measurement this year 260 feet 
above liOng, which seems to imply that 1,584 feet is somewhat too high. 
Just east of Milnagek lies Squaw Lake, a small shallow lake 175 
feet higher by direct measurement, and hence 1,659 feet, the highest 
lake yet measured in New Brunswick. 
Watershed Plateau — (a remarkable facet of the ancient “Cretaceous” 
peneplain) between Island and Little South West Lakes. Mean of four 
measurements with Fredericton as a base, gave 1,725 feet with 1,768 
feet as the highest point reached by us. With Chatham as a base, 
the average of four measurements is 1,667 feet, with 1,697 feet as the 
highest point. The discrepancy in these results will be discussed 
below. 
A small lake on this plateau must be between 1,725 and 1,750 
feet, the highest noted in the Province. 
Little Southwest Miramichi, or Tuadook Lake, also known as 
Big Lake. — ^ Mean of five measurements, with Fredericton as a 
base, gave 1,161 feet ; with Chatham as a base the same five measure- 
ments gave 1,126 feet. The mean, however, of thirteen measurements 
compared with Chatham is 1,136 feet. Ells measured this lake some 
years ago, and gave its height as about 1,200 feet.* 
The Crooked Deadwater at the head of the Little Southwest 
INIiramichi River is by direct measurement about 175 feet above the 
Big Lake, and hence about 1,311 feet. 
Pocket Lake is about 10 feet above Big Lake, and hence 1,146 
above the sea. 
Holmes I^ake is about the same height, as Big Lake. 
Jacks Tjake is by estimation (based upon the small drop from it to 
its junction with the main river in comparison with the large drop in 
the main river from the lake to the junction) about 1,100 feet. 
Junction of the West Branch with the main stream. Mean of three 
measurements, 1,052 feet. This makes the drop from the lake only 
84 feet, which appears l ather small. 
Big Deadwater at junction with the Main North Branch. About 
-30 feet above the latter, and hence 1,082 feet.
