NORTH BAY OF PILLARS. 
The North Bay of Pillars, like the South, is much obstructed by islets and reefs, 
and local knowledge is necessary for safe navigation. The head of the bay, however, 
is clear, and is If miles in length by 1 mile in width, forming a beautiful harbor 
with excellent anchorage in moderate depths. At the extreme northern head of the 
bay are the mouths of two large streams, three-fourths of a mile apart, bordered by 
extensive tidal flats. Neither of these streams is said to carry redflsh, but all other 
species common to the district run here.

PILLAR BAY STREAM. 
This is the western stream at the head of the bay and is the most important, as it 
carries a great number of cohoes of large size. It was examined by Ensign Kempt!' 
August 29 a distance of 4i miles, where it is elevated 40 feet above the sea. 
It flows in a general south-southeast direction between steep banks, heavily 
wooded, over a gravelly bed. The water is clear, of a brownish tinge, as though 
flowing from a lake (though none was found), and at each mile from the mouth the 
temperature was 51° F. Tide water extends 1 mile from the mouth, at which point 
the stream is 9 feet wide, 12 inches deep, and runs a 3-knot current, in the length 
examined two tributaries enter from the eastward, one three-fourths of a mile, the 
other If miles, from the mouth. The stream flows around several islands in its 
course. The eastern channel, around an island about 2 miles from the mouth, has at 
the lower end a rapid about 30 yards long, and at the other end of this, and in the
