LETTER OF TRANSMITTAL. 
Pror. EDwARD ORTON, JR., State Geologist: 
Dear S1r:—JIn accordance with instructions received from you I 
herewith transmit a report upon the Manufacture of Hydraulic Cements. 
In this report I have endeavored to develop the principles underlying 
the processes of cement manufacture in such a manner, that the book might 
be of some value to the cement manufacturer or cement chemist familiar 
with the nomenclature of technical chemistry. 
I am principally indebted to you for the important suggestions and 
help given me in preparing this report as well as for the constant con- 
sideration and courtesy vouchsafed me. Elsewhere I have expressed my 
appreciation of the assistance given me by others. 
Respectfully submitted, 
ALBERT VICTOR BLEININGER.
