This book contains just what the title implies: the project specifications for construction of Seattle's Cedar River Water Supply System. The author, Reginald H. Thompson, was the City Engineer. The book is a hard bound volume, printed on ledger paper, with space for the bidding contractors to enter their proposed prices for various components of the system.

This volume includes the Report to the Mayor and City Council of Seattle, Wash. on Water Works for the City, by Benezette Williams, Chief Engineer.
