Excerpt from Foundry Sands

The following report on foundry sands is based on field work done during July, 1906, and laboratory work carried on in the following winter. The field work was done by the senior author, and the samples collected by him were subjected to a mechanical analysis, and determination of their specific gravit and percentage porosity. In this work Mr. H. Leighton of Cornell University gave valuable aid.

It was deemed desirable, however, to test the permeability of the sands, and this work was later performed by Mr. J. A. Rosen of the Michigan Agri cultural College, whose results indicate, as explained on a later page, that the average fineness as worked out in connection with the permeability test is perhaps on the whole more valuable than that calculated from the sieve test. This does not mean, however, that the mechanical analysis is valueless, or should be neglected.

Before going into the field an attempt was made to obtain as complete a list as possible of the Michigan molding sand producing localities, for the purpose of visiting them.
