ARCHITECTURE OF THE MAUSOLEUM. 87
sides of the pyramid. These stones have ridges along
the back and side joints, upon the upper surfaces, which
meet in such a way on the exposed part of the surface as
to make an eifective weather joint. On the under surfaces
of the upper course are corresponding depressions to take
the ridges of the course below. This step has a height
of 11| inches. The courses above are of the same height,
but have no ridges on their upper surfaces. The treads of
the second and third courses measure resjjectively 9i- inches
and &l- inches, as shown by the setting lines. The upper
step is an angle stone from the top course of the pyramid,
and therefore has no setting lino; the roughly worked
depression on its upper surface shows the relation of the
chariot group to the pyramid. A fragment with a hoof
of one of the horses has been inserted to show the
arrangement.
988. Corner step from the angle of the pyramid. This stone
is similar to the corner stone in the group, No. 987.
989. Group of Mausoleum steps, having various heights and
treads.
The lowest course has a height of 23J inches, with a
setting line 4 inches from the front upj>er edge. The
second course has a height of 11^ inches, and a setting
line 41 inches from the front upper edge. On the lower
part of the front face there is a small raised fillet at each
end, but it is not continued as a weather joint on the top.
(Newton, Hist. Disc, pi. 26, figs. 8, 9.)
The top step has a height of llf inches, and a setting
line which gives a tread of 17| inches. (Newton, Hist.
Disc, pi. 26, fig. 7.)
qqq 991. Two bronze sockets for dowels, each set with lead in
' a piece of marble cut off from the slab in which they were
originally fixed. This was the sill at the entrance of the
underground passage, and was intended to receive the
dowels of the great closing stone, which, however, failed
sides of the pyramid. These stones have ridges along
