Excerpt: ... automatic engine of substantial construction for belted connection to 75 kilo-watt slow speed alternating current generator, with one best oak tanned endless double belt 15 inches wide and 66 feet long. Section 3.

To make certain of this the specifications were re-submitted to the parties who had made propositions and specifications were also given them for the power station and pole line with the request to bid upon the entire plant ready for operation.

Accordingly the bidders were invited to submit propositions on their own specifications. more
