the outside with siding and the space filled with sawdust to the 
roof. Next to the sheathing boards inside is set another row of

matched stuff. The space in this case is left empty for dead air 
space. The walls of the building are thus double, having a layer

and interior partitions are constructed on the same principle.

to July 18, 1897, and from October 23, 1897, to August 14, 1898.
