124 Lieut. Baddeley on the geognosy 
On leaving the mouth of the Koucouathime river, which is 
situated about one mile to the north of the place of our last ob- 
servation, a fine sandy shore marking the interval, our course 
was north west ward to the northernmost point of Koucouathime 
Bay, where the shores begin to be swampy ; but sandy beaches 
were still occasionally observed, with partial deposits upon them 
of the same admixture of garnets and magnetic iron before men- 
tioned. Pu-ting on shore in one place we observed low parallel 
ridges of this sand several inches in width and depth, giving a 
character to the spot. Embarking again the same course was 
followed, and the shores became lower and more swampy as we 
advanced, indeed there appears to be very little difference of 
level between the lake and the land. Tn this portion of the for- 
mer, and from one to two miles from the shore, you are surpri- 
sed to find no more than three feet of water. This extreme 
shallowness is common to the lake (the depth of which in no~ 
part of it bears ayy proportion to its extent) and is the cause 
of the sea-like turbulence its surface asumes after the least 
wird, occasioning a violent ground swell and lofty breakers, to 
which, at a distance from the shore, the hardiest vayageur is fre- 
quently unwilling to expose himself. Upon placing the hand in 
the water on these occasions it felt very decidedly tepid. This 
shallowness and unusual temperature, by occasioning a more ra- 
pid evaporation, may account for a fact which it might other- 
wise be difficult to du, viz: six tolerably large rivers and seve. 
ral emaller ones fall into lake St. John, while only one of mode- 
rate dimensions runs out of it. 
Continuing a northerly course the mouth of the Peribo- 
nea river was reached, where the latitude was found to be 
4.80-4.2'-37", and this was the greatest that was made on the 
lake. 
Tn about three hours after leaving the Peribonea river we 
reached a bay, at the bottom of which we encamped, and found 
a
