The 75-ton crane sank in May 1911. Most of the correspondence pertains to the claim of the Scott Company for extra compensation because the Navy Yard dry dock was not ready to receive the crane when it was raised. The Scott Company had to keep its vessels employed beyond the expiration of the contract to place the crane in dry dock. For this reason, they placed a claim for, and received, extra compensation. Includes correspondence, newspaper clippings, and a memorandum of charges.
