end. Its outlet, at its N. E. extremity, is the Eiver
St. Lawrence. A large number of creeks and rivers
enter the lake on the S. side, the principal of which
are the Genesee, Oswego, and Black Eivers. The
principal bays are those of Quinte and Burling-
ton, in Canada; and Chaumont, Gerondiquot, and
Braddoclt's, on the American shore. The Bay of
Quinte is a considerable body of water, into which
a river descends, forming the outlet of several
small lakes. The shores of this lake are gen-
erally rather low, and in some places marshy;
in other parts, however, they are elevated, and the
land is generally good. The “ alluvial way," so
called, is a remarkable ridge of land from 7 to 10
miles distant from the S. shore of the lake, and
extending in a course nearly parallel to it for a
long distance, having the appearance of being in
some way formed by the action of the lake, at a
period when it may have been higher and spread
over more surface than at present. There is an
excellent road upon the summit of this ridge.
There are a number of good harbors, and several
places of increasing commerce and business, upon
the shores of Lake Ontario, the most important
of which, on the Canada shore, are Toronto,
Kingston, and Coburg; and on the New York
shore, Oswego, Sackett's Harbor, and Port Gene-
see. . This lake is subject to violent storms and
heavy swells; but it is safely navigated by steam-
boat-3, which are large and stanchly built, and by
other vessels. By the Welland Canal, which
connects this lake with Lake Erie on the W.,
vessels are carried around the Falls of Niagara,
and also around the rapids in the upper part of
the St. Lawrence. It is connected with the Erie
Canal and the Hudson Eiver by a canal from
Oswego; and much valuable trade to and from
New York passes by this channel through the
lake. Ontario has such a depth of water that
even its harbors are seldom closed or much ob-
structed by ice. Daily lines of steamboats run
through the lake from Ogdensburg, on the Eiver
St. Lawrence, to Lewiston, touching at all the in-
termediate ports. Sackett's Harbor, at the mouth
of Black Eiver Bay, about 150 miles N. from Os-
wego, is one of the best and most secure harbors
on Lake Ontario. It was an important naval and
military station during the last war with Great
Britain.

Ontonagon River, Mn. This large river drains
the W. part of the upper peninsula. Its E. branch
rises in Marquette co., its middle and S. in small
lakes near the border of Wn., and its W. in
Gogebic Lake. The main stream flows in a N.
N. W. direction, and empties into Lake Superior.

Oostenaula River, Te. and Ga., rises in Te.. and
unites with the Etowah in Floyd co., to form
Coosa Eiver.

Opequan River, Ya. This river rises in the S.
E. part of Frederick co., flows N. E., separating
Clark and a part of Jefferson from Frederick and
Berkeley counties, and empties into the Potomhc
Eiver.

Oquossak Lake, Oxford co., Me. This large
sheet of water lies a few miles N.E. of the Moose-
luckmaguntic. It is irregular in its form, and con-
tains many islands.

Orange Lake, Fa. This is an irregular sheet
of water lying in Alahua and Marion counties.
Its outlet connects with the Ocklawaha, a branch
of St. John's Eiver.

Oriskany Creek, N. Y., a very important mill
stream, on which are situated extensive cotton and
woollen factories, rises in Madison co., and falls
into the Mohawk at the village of Oriskany, Onei-
da co.

Orphan's Lsland, Penobscot co., Me. This beau-
tiful island, containing about 5000 acres of land,
lies at the mouth of Penobscot Eiver, and is 4
miles in length. Its N. part lies opposite the
town of Bucksport, to which it is attached. It
divides the Penobscot into two branches, the W or
main branch of which is called the “ Narrows,"
on which side is a fort constructed by the U. S.
government. The other branch is called E. Eiver.
The island derived its name from having been the
property of an orphan who inherited it as her part
of the Waldo estate.

Osage River, Mo., has its source in In. Ter.,
flows into Mo., and after a winding course through
fertile borders, falls into the Missouri 133 miles
above the Mississippi. It is 397 yards wide at its
mouth, and navigable for steamboats 200 miles.

Osalcis River, Ma., is supplied by numerous
lakes, and flows W. into the Mississippi.

Ossabaw Island and Sound, Bryan co., Ga., are
situated at the mouth of Ogeechee Eiver. The
island is flat and sandy, and 10 miles long; and
the sound is an inlet between this island and
Warren Island.

Ossipee Lake, N. H. See Ossipee.

Ossipee Mountain, N. H. See Ossipee.

Oswegatchie River, N. Y., rises in Herkimer co.,
and pursues a winding N. W. course until it enters
the St. Lawrence at the village of Ogdensburg,
St. Lawrence co.

Oswego River, N. Y., furnishes the final outlet of
the small lakes in the interior of the state of N. Y.
into Lake Ontario, into which it flows at the town
of Oswego, on the S. shore. The Oswego Eiver
flows directly from the outlet of the Oneida
Lake, and receives the waters of the other small
lakes by the Seneca Eiver, into which their sev-
eral outlets are discharged, and which unites with
it about 24 miles from its mouth. Its course is
about N. W. The lakes with which it is con-
nected are, besides the Oneida, Fish, Gross,
Otsego, Onondaga, Owasco, Skeneateles, Canan-
daigua, Crooked, Cayuga, and Seneca Lakes.
This river, for the greater part of its course,
serves the purpose of the Oswego Canal, con-
necting the Erie Canal at Syracuse with Lake
Ontario, the falls of about 100 feet, 12 miles from
its mouth, being overcome by lockage. From
the foot of these falls the canal is carried along
upon the E. bank of the river to its mouth, where
it descends by locks to the level of the lake. An
immense water power is furnished by this canal
for mills and manufacturing purposes at Oswego.
This river served in early times as the great
channel of intercourse between the French, and
subsequently the English, in Canada, and the
Six Nations of Indians in Western N. Y. It
was not, however, navigable from the lake, on
account of the fills at its mouth.

Otego Creek, N. Y., rises in Burlington, Otsego
co., and flows into the E. branch of the Susque-
hanna. It affords good water power.

Otisco Lake, N. Y. This beautiful sheet of
water lies in the W. part of Onondaga co., sur-
rounded by romantic scenery, and is 5 miles long
and 2 miles wide.

Otsdaiva Creek, N. Y., rises in Laurens, Otsego
co., and flows S. into the Susquehanna Eiver.

water lies in the N. part of Otsego co. It is 9
