This ridge runs midway between Eleventh and
Twelfth avenues as far 10th street. between
which and along the crest of the ridge has been
laid out sinuous avenue from Seventy second
street to l29th street. The Riverside Park begins
at the former street, with width of half square,
and stops at Eghty-ffth street, where the River
bank avenue is merged into the Twelfth, and con-
tnues to run parallel Herewith, or rather
divided from 1t by Q terrace wall Of
seventy feet in height, to Eighty.
ninth street. At Seventy ninth street one
cross thoroughfare is yielded and from Eighty.
fifth to Eighty-nnth street, inclusive. five more
cross streets have been extended to the river. At
Eighty ninth street the Park is again resumed and
continues to 10th street, with an average width
of half square. At Ninety sixth street another
cross thoroughfare is gained. The Rverbank
avenue is to be improved simply as border to the
Riverside Park and will form one Of the most
elegant situations for villas and splendid resi-
dences to be found anywhere in the world. In
fact, In many respects, its lots cannot but be
preferable to those Of the Park border. From
ll6th to l27th street only two cross streets
are continued to the Riverside Park, or
rather the Riverside avenue; and a narrow par.
abel avenue has been made to run midway be-
tween Eleventh avenue and that on the crest.
l3sth street has also been discontinued for half
square between Eleventh add Twelfth avenues,
owing to the Intervention Of high bluff of rock
The Boulevard, which continues Broadway from
its junction with Eighth avenue and Fifty-nnth
street, claims second attention. Beginning in the
grand circle, 432 feet in diameter at this junction
and diverging from Eighth avenue at angle Of
thirty-eight degrees, it crosses diagonally the
paralelogram formed by Fifth-nnth street, Sixty
fifth street. Eighth avenue and Ninth avenue, and
thence divergng from Ninth avenue at the same
angle it cuts Tenth avenue at Seventy street.
Thence, diverglng from Tenth avenue at the same
angle, it curves gracefully, cutting Seventy
street midway between Tenth and Eleventh ave.
nues and, thence, is continued in straight line
and midway between the two avenues to l03d
street. At 103d street it bends westerly at an
angle OF one hundred and fifty degrees, and cuts
Eleventh at an angle of about thirty degrees,
uniting with it. The transverse thoro ughlares of
main importance, therefore, arc indicated by
these several functions, and will be respectively
Fifty.ninth, Sixty-ifth. Seventy.second and l0Gth
streets-the latter Of which will undoubtedly,
from certain felicity Of situation, form the most
important of all cross streets west Of the Park.
The Ninth avenue continues IN straight
line to 10th street, where it bends westerly at
angle Of one hundred and fifty degrees, continues
direct to 1l5th street, which 1t cuts at the distance
Of half o square east Of Tenth avenue, whence it
takes northerly bend and keeps at the same dis
tance from Tenth avenue as far as 120th street.
Thence, with a sweeping curve, IL rounds l2lst
street and joins Tenth avenue at l22d street. This
variation Of Ninth avenue from 10th street to its
junction with Tenth avenue, together with the
length of one square on Tenth avenue forms the
western boundary Of Morningsde Park, which
occupies . space Of thirteen squares in
length. From 10th street the new avenue

avenues as far as the Convent grounds, which,
rounding with q slight curve, 1t passes and runs
directly north on the line which would naturally
be occupied by Ninth avenue. From 10th to
Hath street this avenue forms the eastern bound
ary of the Morningside Park; and from the latter
point an avenue has been cut diagonally to l16th
street, where it takes up the old mathematical
line of Ninth avenue and continues TO the Con.

the Morningside Park. Tho land to be taken fox

MANHATTAN STREET.
The Manhattan valley is marked by Manhattan
street. 100 feet wide, which runs from the junction
Of l24th street and the avenue above described to
the Hudson river, where ;t forms Q junction with
13oth street. This street, being Of easy grade, is
likely to form one Of the great west side thorough.
