If a picture is worth a 1000 words, then this otherwise well written and informative book has been robbed of several 100 thousand. While the deletion of the book's original illustrations in a novel is of minor importance, this practice in the case of an instructional book such as this one is devastating in it's impact on the usefulness of the volume.
The remainder of the manual presented here is an extended preview of the work the author intended, suitable for the casual historian or as incentive for the serious student of the field to locate a true, complete version of the work.

A very well done period thesis concentrating on the construction of a water wheel system for electric power, marred by the lack of any of the text illustrations originally included in the book. This loss of such illustrations as:

Measuring a stream with a weir,

A direct-current dynamo or motor, showing details of construction

Details of voltmeter or ammeter

A tangential wheel, and a dynamo keyed to the same shaft

and a Ward Leonard-type circuit breaker for charging storage batteries

greatly reduces the practical value for the book as a construction guide and reduces it to a general reference guide.
