Mr. H. Durnford^s Notes on the 
From the time I arrived at the colony till the 22nd Oc¬ 
tober I was engaged in collecting in the neighbonrhood. 
of Chupat. On that date I started with two of the colonists 
on an expedition to Lake Colguape* and the river Sengel. 
This is not the place to give an account of our expedition; 
but to enable my readers rightly to understand the following 
notesj I will rapidly run over the route we adopted. 
We followed the sea-coast as far as Montemayor height 
(cutting off the points)^ which we reached on the 31st Oc¬ 
tober. On the following day we returned by compass W. 
by S._, and the day afterwards W.S.W.^ arriving in the after¬ 
noon on the banks of a little river_, which we called the Sen- 
gelen (the Welsh diminutive for Sengel) ^ which flows from 
the lake to the river Chupat. Following this river up^ on 
the 8th November we reached the lake; and this point I con¬ 
sider, from dead reckoning from my daily journal and from 
two observations I made with a box-sextant I carried with 
me, to be in about lat. 45° 50' S., long. 68° 40' W.; but I do 
not pretend to scientiflc accuracy. One of my companions 
places the lake in about the same position as I do; my other 
companion considers it further south. The difference be¬ 
tween the point flxed by my observations with the sextant 
and my dead reckoning is only nine miles; and I therefore 
think I am not far out. We calculated this lake to be about 
twenty miles in length and fifteen in breadth; and after 
travelling along its southern and a portion of its western 
shores, we arrived, on the 10th November, at the river Sengel, 
which we found flowing into the lake. Continuing our 
journey up the river on the 11th, we came in sight of another 
large lake; but it being on the other side of the Sengel to the 
one we were on, we were unable to visit its shores. This 
lake, if not as large as the first-mentioned, has a greater 
^ The Tehuelche Indians call this lake Colbut as it is marked in 
many maps Colgiiape, though certainly placed in an entirely wrong posi¬ 
tion, I think it is better, in order to save confusion, to call it Colguape. 
‘‘Col” is the name used by the southern Indians for a lake, whilst 
“ Guape,” is employed by the Moluches and northern Indians to designate 
the same thing.
