 command may carry, where they can best be seen, 

 and in lieu of the light prescribed in section

 line, one over the other, not legs than 3 feet apart, 

 and of such a character as to be visible all round 

 the horizon at a distance of at least 2 miles, and may 

 by day carry in a vertical line one over the other 

 not less than 3 feet apart, where they can best 'be 

 seen, two black balls or shapes, each not less than 2 

 feet in diameter. 



(c) A vessel engaged In laying or in picking up a 

 submarine cable or navigation mark, or a vessel en- 

 gaged in surveying or underwater operations, or a 

 vessel engaged in replenishment at sea. or in the 

 launching or recovery of aircraft when from the 

 nature of her work she is unable to get out of the 

 way of approaching vessels, shall carry, in lieu of 

 the lights prescribed in section 1062(a) (1) and (ii), 

 or section 1067(a) (i) of this title, three lights in a

 and not less than 6 feet above or below, the middle 

 light. The highest and lowest of these lights shall 

 be red, and the middle light shall be white, and they 

 shall be of such a character as to be visible all round 

 the horizon at a distance of at least 2 miles. By

 (11) the showing of these lights or balls indicates 

 that it Is dangerous for other vessels to approach 



closer than 3,000 feet astern of the minesweeper or 

 1,500 feet on the side or sides on which danger exists.
