1904] W. N. Edwards & H. H. Mann —Assamese Fortification. 
in Lat. 26° 57'N. and Long. 93° 28'E. 1 They consist now of two long 
walls situated as shown in the sketch map. That marked A which is 
by far the longest, consists of a long continuous barrier made of faced 
sandstone blocks, put together with great precision. The general 
character of this wall is shown in the accompanying photographs (see 
Plates V and IV) which we were able to procure. Plate IV, No. 1 
shows most clearly the accuracy with which the stones are keyed into 
one another. 
This wall was some ten feet in thickness, and the inside appeared 
to be filled in with ordinary river stones, without any arrangement. 
It ran from N.E. to S.W. or nearly so, and commanded the right bank 
of the river. It was from its arrangement and structure evidently 
used as a fortification against the plains, as while it was protected most 
completely on the South side, it lay almost entirely open from the hills. 
The North end was protected by the sheer cliff on the opposite bank of 
the river shown in Plate IV, No. 2. 
The place is difficult of access, and in part buried in cane jungle. 
On a second visit, when there was more leisure to examine the whole 
situation and material of the fortification, it was found to be three 
hundred yards long, and a very large number of the blocks of stone of 
which it is composed, on being cleared showed marks, which we take to 
be builder’s marks, cut deeply into the sandstone, and always on the 
outside face. Some of these marks are shown in the accompanying 
diagram, (which does not of course represent an actual group of 
Fig. 2. Marks found on stones in the Buroi fortifications. 
marks but is purely diagrammatic). That to the left hand on the top 
row is by far the most common. It is a curious point to note that some 
of these same marks were found on the worked stones at Raja 
Bhismaka’s temple near Sadiya by Colonel Haunay, in 1848, indicating
