PYRAMIDS OF DJIZA. 197 
graiiite, except that the red feldspar enters more ^!l^^- 
largely as a constituent into the mass than is ' / — ' 
usual in the granite of Europe\ So exquisitely 
are the masses of this granite fitted to each 
other upon the sides of this chamber, that, being 
without cement, it is really impossible to force 
the blade of a knife between the joints. This 
has been often related before ; but we actually 
tried the experiment, and found it to be true\ 
There are only six ranges of stone from the 
floor to the roof, which is twenty feet high; and 
the length of the chamber is about twelve yards. 
It is also about six yards wide. The roof or 
ceiling consists only of nine pieces, of stupen- 
dous size and length, traversing the room from 
side to side, and lying, like enormous beams, 
across the top. 
(4) The author has seen granite of the same kind, and of equal 
beauty, in fragments, upon the shores of the Hebrides, particularly at 
Icolmkill. 
(5) Diodorus particularly alludes to the same thing. " But this 
work," says he, " is not only worthy of praise on account of its mag- 
nltude, but wonderful for the skill displayed, and remarkable for the 
nature of the stone ; since that in so much vastness there was not a 
fissure nor a blemish visible." To Js 'i^yef revra fih fAoioti uvai xara to
