SCOPE OF INVESTIGATION. 63 
personal examination would consume a great deal of time. It also 
disclosed the fact that an examination was in process by competent 
engineers, and Major McKinstry undertook to get for me a report of 
the results of this examination. As a matter of fact, I have been 
allowed to see a copy of such a report made by Charles D. Marx 
and Charles B. Wing, which the authors prefer not to have pub- 
lished as yet. However, certain essential facts as to the condition 
of dams, conduits, etc. (see Pis. IX; X, A; XI, Z?), are taken from it 
and embodied further on in my own report ; although the photographs 
and certain other features of the report itself, which seem to be pecul- 
iarly the property of its authors, are not submitted herewith. In 
view of the fact that the results of the examination of the waterworks 
were promised to me, it seemed superfluous for me to visit the dams 
and conduits, except as a matter of .personal interest, and as my time 
was very short, I decided not to do so. 
The light-houses and fortifications are in charge of competent offi- 
cers, whose duty it is to report the nature and extent of the damage 
done to them by the earthquake. As an inspection of the light-houses 
would have involved a great deal of time, I decided not to attempt 
to visit them, and made only a superficial examination of the forti- 
fications. 
As my own experience has been mainly in the line of fireproof 
buildings, however, I made a very careful inspection of the ruins of 
San Francisco itself, and also visited Oakland and Palo Alto, with 
a view to inspecting damaged buildings at those points. I found, as 
a result of those trips and by inquiry among competent witnesses, 
that, with one exception, there was no type of building in the affected 
district which was not well represented among the buildings of San 
Francisco. The exception was the concrete work at Leland Stanford 
Junior University, near Palo Alto, to which specific reference is 
made on page 113. The greater part of my time, for the reasons 
above outlined, was spent within the limits of San Francisco itself, 
and much of it within what had been the congested district of the 
city. 
ACKNOWLEDGMENTS. 
Acknowledgment is due to Capt. M. L. Walker, Corps of Engineers, 
commanding officer at Fort Mason, who not only entertained me at 
his quarters during my stay in San Francisco, but rendered very 
material assistance in the way of transportation when needed, and 
especially in placing at my disposal the services of Private William H. 
Hughes, of the First Battalion of Engineers, a very efficient photog- 
rapher, who accompanied me and took such views as seemed desir- 
able for the purposes of my report. I was also much indebted to 
Maj. C. II. McKinstry, Corps of Engineers, who gave me much
