4. Street cars, wagons, or other vehicles shall not be stopped on the bridge, or any part thereof, or allowed to come upon it after the signal for the opening of the draw has been given, for the purpose of delaying the operation of the draw span; nor shall a vessel be so manipulated as to unnecessarily delay passage through the draw span or hinder the operation thereof, but passage over, through, or under the bridge, shall be so conducted as to prevent unnecessary delay either to land or water traffic.

5. The owners of the bridge shall provide and keep in good legible condition two board gauges painted white, with black figures not less than six inches high, to indicate the head-room clearance under the lower chords of the closed draw span at all stages of the tide. The gauges shall be so placed on the ends of the draw-span fender that they will be plainly visible to the operator of a vessel approaching the bridge either up or down stream, and the said gauges shall be illuminated at night.

6. Vessels which can pass under the bridge with a clearance of two feet or more should not signal for the opening of the draw. In case such a vessel gives the prescribed signal and the draw tender is uncertain as to whether the vessel can safely pass, he will open the draw and if he finds that there would have been a clearance of two feet or more had the draw remained closed, he will report the matter immediately to the district engineer, United States Engineer Office, Portland, Maine, giving the name of the vessel, the time of opening the draw, the headroom under the bridge as indicated by the gauge at the time of opening the draw, and the approximate headroom required by the vessel.

7. These regulations shall be effective on and after May 1, 1918, and shall supersede those prescribed December 18, 1894.

[The law-Secs. 10, 12, and 17 of act of Congress approved March 3, 1899.] 1

The attention of those engaged and of those who propose to engage in weir. trap, and pound fishing in the coastal waters of Massachusetts, from the boundary line between New Hampshire and Massachusetts to the mouth of Bass River, is called to the provisions of sections 10, 12, and 17 of the river and harbor act of March 3, 1899."

In accordance with the above, and until further notice, all weir, trap, and pound fishermen who desire to operate within the waters above described, and under conditions stated as follows, but not otherwise, and whose written applications may receive the approval of the district engineer, Engineer Department at Large, in charge of the locality, are hereby authorized by the Secretary of War, subject to the following conditions, to construct and maintain fish weirs, traps, and pounds, constructed in the usual manner as heretofore, in the said waters within the approved areas shown by cross shading on certain maps entitled "Areas Available for Fish Traps, Boston, Mass.. District,” designated as E. D. 117699/13, 14, and 15, copies of which are on file in the U. S. Engineer Office, Customhouse, Boston, Mass.

The said district engineer is charged with the duty of supervising the enforcement of the spirit and letter of the above law and these regulations.

CONDITIONS.

1. All persons desiring to fish under this permission shall make application to the district engineer, Engineer Department at Large, in charge of the locality, whose address is U. S. Engineer Office, Customhouse, Boston, Mass., giving their names, their addresses, the proposed location of their structures, and evidence that the proper license has been granted by the State or municipal authorities in cases where the laws prescribe such requirements, or evidence showing that there is no State law or municipal regulation relating to the subject. They shall also report to him all changes of locations of fishing structures, transfers of location or ownerships to other parties, or abandonment of the locations of the fishing business and all changes in the number of the State or municipal fishing license under which the structure is built and operated.

2. That this authority does not give any property rights either in real estate or material, or any exclusive privileges; and that it does not authorize any injury to private property or invasion of private rights, or any infringement of Federal, State, or local laws or regulations, nor does it obviate the necessity of obtaining State assent to the work authorized. It merely expresses the assent of the Federal Government so far as concerns the public rights of navigation. (See Cummings v. Chicago, 188 U. S. 410.)

3. That all apparatus used and work herein authorized shall be subject to the supervision and approval of the aforesaid district engineer, who may temporarily suspend the work at any time if, in his judgment, the interests of navigation so require.

4. That no structure shall be located or built in such place or manner as to unreasonably obstruct or interfere with navigation.

1 See Appendix.

5. That on the outer end of each trap the owner shall maintain a sign “U. S. No." (the number being that specified by said district engineer) with letters and numerals not less than three inches in height, capable of being readily read from passing vessels at a distance of 100 feet, and failure to keep such sign conspicuously displayed shall be a sufficient reason for cancellation of the permit and for prosecution as provided for in section 12 of the aforesaid act of Congress.

6. That upon ceasing to use any structure as herein authorized, such structure shall at once be removed by the owner thereof at his own expense and to the satisfaction of the aforesaid district engineer. Failure to so remove the same shall be considered sufficient ground for prosecution of the owner for maintaining illegal structures endangering navigation, as set forth in sections 10, 12, and 17 of the aforesaid act of Congress.

7. That on or before January 10th of each year, every person holding a permit shall notify the district engineer in writing to what extent the permit was made use of during the preceding calendar year. Failure to furnish such information shall make the permit null and void after that date. Failure to place an authorized trap for two successive calendar years shall make the permit therefor null and void so far as that particular trap is concerned, and the location will be considered available for other applicants.

8. Permits shall not be transferred except by consent of the district engineer indorsed thereon, specifying the person to whom the transfer is made.

9. That if future operations by the United States require an alteration in the position of the structure, or if the latter, in the opinion of the Secretary of War, shall cause unreasonable obstruction to the free navigation of the said waters, the permittee will be required, upon due notice from the Secretary of War, and within thirty days thereafter, to remove or alter the structure, or obstructions caused thereby, without expense to the United States, so as to render navigation reasonably free, easy, and unobstructed. No claim shall be made against the United States on account of such removals or alterations.

10. That fishing structures and appliances in navigable waters of the United States shall be lighted for the safety of navigation, as follows:

"The lights shall be displayed between sunset and sunrise. They shall be placed at each end of the structure excepting where the inner end terminates in such situation that there is no practicable navigation between it and the highwater line of the adjacent coast, in which case no inner light shall be displayed. The outer light shall be white and the inner light shall be red. The size, capacity, and manner of maintenance of the lights shall be such as may be specified in the War Department permit authorizing the erection of the structure or appliance.

"When several structures or appliances are placed on one line with no navigable passage between them, they will be considered, for lighting purposes, as one structure."

Each light shall have a capacity to burn untended for eight days. The lights shall be placed at an elevation of not less than 10 feet above the plane of mean high water. All lights shall be subject to inspection by the district engineer before use. The owner of the structure will be responsible for keeping his lanterns in good condition and for the proper maintenance of the light during the hours above prescribed.

11. That there shall be installed and maintained on the structure by and at the expense of the permittee, such additional lights and signals as may be pre

scribed by the Bureau of Lighthouses, Department of Commerce, and that provision shall be made by watchman or otherwise for proper attendance of lights and signals, so that they will at all times be in effective condition.

12. That this authority is revocable at will by the Secretary of War, and unless previously revoked under paragraph 9 or become null and void under paragraph 7 above, shall cease and be null and void after a date to be specified by the district engineer which shall not exceed five years after date of issuance of permit.

5. Trains, cars, vehicles, or persons shall not be stopped on any draw span for the purpose of delaying the opening of the draw, nor shall any vessel or other water craft be so handled or placed as to delay the opening or closing of any draw span, but all passage over, under, or through a draw span shall be prompt so as to reduce delays to water and bridge traffic to a minimum.

6. The owner or owners of every bridge covered by these rules and regulations shall maintain in good and efficient order the draw span and the machinery and appliances for operating the same and for assisting vessels while passing through the draw. The said owner or owners shall also provide and maintain at the draw span such number of draw tenders or operators as may be necessary to open and close the same promptly; and they shall also provide and maintain in good order on the bridge piers or fenders such fixtures as may be necessary to vessels in mooring or making fast while waiting for the draw span to open.
