from the photographs. The plans of the survey give a sufificiently accurate 

 representation of the main physical features for present requirements. 



The whole survey was carried out in such a manner as to form part of 

 the ground control necessary for plotting oblique aerial photographs for a con- 

 siderable distance on either side of the traverse, and particular care was taken 

 to accurately locate small islands, sharp points and other physical features 

 which it was thought could be easily identified on the photographs. Below 

 Marten Falls the Albany River runs in a series of long sweeping curves, and is 

 of such a nature that points easily identified on the photographs are not nearly 

 as numerous as they are farther up-stream. 



Posts were planted at intervals of about three miles along the shore and 

 marked consecutively as in previous years. Stone mounds were built around 

 these posts and bearing trees were marked and recorded in the field notes where- 

 ever suitable trees were at hand. A large number of posts, however, have no 

 bearing trees, as very often the most suitable place for a post is on a rocky point" 

 or in some other place bare of timber. In cases such as this there is very little 

 danger of the post being destroyed by fire. Every wooden post is surrounded 

 by a substantial mound of stones. 



Twenty-three metal posts were planted along the river. The most of the 

 metal posts planted above Marten Falls were placed near waterfalls where they 

 can be used as bench-marks. Below Marten Falls the problem of finding suitable 

 places to plant these metal posts was a difficult one. The river in this section 

 occupies a deep valley with high clay banks subject to very severe floods at 

 times. The wooden posts could not be planted below the extreme high water 

 mark or they would be washed away by the floods, and the metal posts could 

 not be planted much above the ordinary water level owing to the absence of 

 reck in which to cement them. It was found, however, that large boulders, 

 which have every appearance of being permanently located, occur all along the 

 river banks above the ordinary summer level, but considerably below the extreme 

 flood level. The metal posts were cemented into holes drilled into these boulders 

 and tied to the nearest transit station. A wooden post was also planted above 

 the flood level and tied to the same station. 



The Albany River, from the point where the survey commenced to Marten 

 Falls, is a large river with several lake expansions and is broken with numerous 

 rapids and falls. Makokobarter Lake is the first of these lake expansions and 

 is about sixteen miles long and from half a mile to nearly two miles wide. The 

 shores are low with sandy and stony beaches, particularly on the north side. 

 From Makokobarter Lake to Washi Lake is a distance of nine miles and the 

 river flows with a swift current broken with several rapids at two of which 

 portages are necessary. The Albany River falls thirty-three feet between 

 Makokobarter Lake and Washi Lake. 



The Albany River enters Washi Lake on the south side and flows out of 

 the north-east end of the lake about four miles from where it enters. Two miles 

 west of where the river enters Washi Lake the lake narrows for some distance 

 and then widens out into a lake expansion nearly as large as the easterly portion. 



Makokobarter Lake has two outlets, the northerly one being the one most 

 used by travellers. The southerly outlet is a large stream and is said to be very 

 rapid throughout its entire course. It rejoins the main river in a small lake 

 expansion about four and a half miles below Washi Lake. 



From the point where the southerly outlet of Makokobarter Lake rejoins 

 the main river the general course of the Albany River is a little north of east 

 for over six miles, and the river flows with a gentle current broken by a couple
