p. 110be used are broad enough to include them, and the specific provision for loading and trimming “dumpers” in the Clarke contract makes clear, in my opinion, the right of the plaintiffs to use them. That being so, paragraphs “F,” “N” and “33” of their contract cannot be construed so as to give the commissioner of street cleaning power to abrogate this right. The authority given to that official may be exercised as to details of the work and in case of ambiguities or obscurities in the language of the contract but not to the extent of destroying its identity or mutuality. The dumping at sea, as carried on by the plaintiffs, is in accord with the laws, rules, and regulations of the state, city, and federal governments; and, indeed, the defendant through the commissioner of street cleaning does not object to the dumping at sea, but merely to the use of dumping scows, upon the sole ground that in loading them the pickers under the Clarke contract cannot so thoroughly do their work as in the case of deck scows. That may be so, but there is no claim that full freedom of action is not given to them to pick as much as the nature of those conveyances will permit, and that is, in my opinion, the only duty owing either to the city or to the other contractor by these plaintiffs under their, contract. The damage done to the contractor by a prohibition of the use of dumpers would be of such a nature as, in my opinion, to call for equitable relief. Judgment for the plaintiffs. Settle findings on notice not later than June 12th.
