[illegible], no possibility of [illegible]. Two [illegible] of such
Brick lay a 16 inch wall with 4 inch hollow. Of course some
Bricks would be needed if different heights to [illegible]
June 26th. I think that the Corwin A hollowed out as I have
Devised can be much more easily handled by the brick mason
Than a much lighter brick with no hollow. [illegible]
Into the brick and it might [illegible] without [illegible]
And the mortar thus much more easily put on the joints of
[illegible] of the outside wall [illegible] bricks it
Would be too expensive to lay that [illegible] of any larger size than
The regular A Corwin. Might not two persons work together
On the wall as follows. One the workman skilled to lay the [illegible]
[illegible], the other the ordinary [illegible]. When the large 8 1/2 x 8 1/2 
Etc. block is to be put in position they each take hold of it
by the shoulders. If [illegible] brick are not used the
big bricks might be laid easily by the [illegible] of two men. 
They each [illegible] put in place
[illegible] bricks. I can see no reason why even
Larger bricks than 8 1/2 x 8 1/2 etc. might not by this [illegible]
Be easily handled, brick as heavy if desired as three large
Hollow Chautauqua Falls New York bricks. What a [illegible]
Might be made of brick laying [illegible]
[illegible]
