A second bearing may be taken by compass at sunset, by reversing the east bearing given for the nearest latitude, as the change in declination for a few hours makes but a slight difference in the true bearing of the sun’s setting. The bearing may be taken when the sun’s center is on the horizon, rising or setting. The ele- ments which may be obtained by taking these amplitudes are the quantities known as local attraction, variation and deviation, or the total difference between compass and true, or geographical bearings.

With a compass correct magnetic, the difference between the observed and true bearing or amplitude will be the vari- ation for the locality. Should there be any deviation on the course the vessel is heading at the time of taking the bear- ing, the difference between the observed and the true am- plitude after the variation is applied will be the amount of deviation on that course. If the correct magnetic beating is to the right of the compass bearing, the deviation is east- erly. if to the left, the deviation is westerly. ——— oO So Fog—Negligence of Tug—A tug, having in charge eight canal boats in three tiers, tied them up on reaching a pier in the East River at about 1 a. m., to await a favorable condition of the tide before proceeding further. The night was then clear, and the tug left the tow to.engage in other work. At 3 o’clock a fog came on, and later in the morning became very dense. ‘Ihe canal boats, when left, tailed down the river with the ebb tide, but when the tide rose gradually swung out across stream, and, while lying thus, about 6:30 a. m., a ferry boat collided: with one of the canal boats and injured it. When the fog. began to rise, the tug was a very short distance from the tow, and had only two light boats in charge, and could have re- turned to the tow. Held negligence on the part of the tug, and that it was liable for the injury. Hughes vs. Pennsylvania R. Co., et al., 113 Fed. Rep. (U. S.) gas.

I0O “ ce “6 6 11,47 6c cc LAKE ERIE LEVELS. ‘A meeting of the Lockport Business Men’s Association has been called to take action relative to the proposed in- ternational commission, which is to consider the lake levels question. Lockport is not a lake port, but it is deeply interested in the question which has to do with the maintaining of the lake levels. The surplus water of the Erie canal, created by the operation of ten combined locks, furnishes water for a score of manufacturing estab- lishments 11 months in the year. ‘Ihe municipal water supply for fire protection and sanitary purposes is also taken from the Erie canal, which is fed from Lake Erie. It is understood that there is considerable sentiment here for the appointment of George Clinton, of Buffalo. —— oro Death of Passenger.—Where a girl takes passage on a steamboat, and is drowned upon reaching the point at which she expected to leave the boat in an attempt to transfer her to a skiff, the burden of proof rests on the carrier to show that such occurrence did not result from the fault of his officers or representatives. ‘There is dan- ger in attempting such transfer at night, and whilst the boat is in motion, of which the carrier ought to be aware, and to which he has no right to subject an ignorant and inexperienced passenger; and in so doing he assumes the risk of the consequences, Le Blance et ux. vs. Sweet et al., 31 «So.
