Lights — Southern point, — A circular white tower, 59 feet high, 

 on the summit of the southern point of Belle isle, exhibits, at 470 feet 

 above high water, an intermittent white light every ten seconds, thus :

 of 228° between the bearings 242° and 110°, and should be seen from 

 a distance of 28 miles in clear weather.

 on a masonry foundation below the high light-house, exhibts, at 124 

 feet above high water, an intermittent white light every ten seconds,

 by the high land of Belle isle. 



In fog the high light may be obscured when the low light is visible, 

 or the reverse may be the case.

 between tlie high and low lights at the southern point of Belle isle and 

 250 feet above high water, gives two blasts in succession, of a high 

 note and a low note, respectively, every two minutes, thus: Low blast,

 seconds, during thick or foggy weather. The siren is worked by 

 compressed air.

 sive bombs has been installed as a reserve fog signal. Should the fog 

 siren at this station become disabled, cotton powder bombs will be

 in dangerous proximity an additional shot will be immediately fired, 

 and the firing will be continued at intervals of five minutes until the 

 vessel has passed the station.
