About 14 inches might perhaps safely be taken out of corwin A [illegible] 
making its content just about same as 2 1/2 x 4 1/2 x 8 1/2 brick 
June 26th [illegible] had some wooden blocks made full size 
of the bricks I am much pleased with the plan of the 
hollow and the saving of materials. I find them so 
Easily handled (the fingers going into the hollow) that it seems 
as though the bricks might be made six inches thick on the 
three inch [illegible] that they would [illegible] 
[illegible] burn well, an each [illegible] made to
built twice the [illegible]. Of course they could not be
Handled so rapidly but yet could be made to build 
faster, and would make all the face bricks 8 1/2 x 8 1/2 
and give a very fine appearance to the buildings. The 
hollow in them would be made in the double sized 
break to take more out of the brick so that the new 
size would not weigh as much as two of the old size. 
This plan makes one brick to lay outside and the 
same inside of wall, and only two [illegible] needed 
to get a proper hollow and [illegible] with metallic binders 
a very strong wall could be got. [illegible] why cannot 
the brick be made of four combined in one so as to lay a 
square brick 8 1/2 x 8 1/2 [illegible] would weigh less than 
[illegible] and [illegible] more wall could be 
laid in a [illegible] time than with single brick [illegible] 
hollow in these bricks would [illegible] them to dry well, [illegible] 
[illegible] what a beautiful wall all
