ion of the work was performed by the 15th of August, at which
period it was considered inexpedient to incur the expense of continuing
it any farther.

A party under the direction of another officer of Topographical
Engineers, which took the field also in July was charged with the
surveys of the Little Madawaska River, the Eagle or Cheaplawgan Lakes,
the portion of Fish River from the outlet of Lake Winthrop--one of the
Eagle group--to its debouche into the St. John, of the river St. John,
thence to the meridian of the source of the St. Croix, and finally of
the Alleguash from its mouth to its source.

The Little Madawaska was ascended in bateaux from its mouth to its
source, which is found in the Madawaska Lakes, and a trace of the river
was made by coursing with a compass and estimating the distances, which
were checked by astronomical observations for latitude and longitude.

The position of its mouth had been fixed by the surveys of the preceding
year, and observations for latitude and longitude were made at a point
intermediate between its mouth and its source and also at the junction
of the two lakes which form its source. The trace of the river was
corrected so as to agree with the results of these observations before
being laid down upon the map.

A portage of 5-1/4 miles was cut from the Madawaska to the Eagle Lakes,
which are only 4-3/4 miles apart in a direct line. The party transported
their baggage and boats by this portage and launched them on Lake
Sedgwick, the most southern and largest of the Eagle group.

This group, which is composed of the Winthrop, Sedgwick, Preble, Bear,
and Cleveland lakes, being all connected one with another by water
communications between them, was carefully surveyed by triangulating
them and coursing their shores with the chain and compass, except those
parts which were so straight as to render the work sufficiently accurate
by sketching those portions between consecutive points of triangulation
of no great distance apart. They were also sounded so far as to obtain
their general depths.

The survey was continued from the outlet of Lake Winthrop down Fish
River to its mouth, which was found to be the only outlet from this
group to the river St. John.

Lake Cleveland, the most northern and deepest of the group, was
connected in position with the river St. John at a point 2 miles below
the upper chapel of the Madawaska settlement, by a chained and coursed
line following the
