St. JoseEpH CHANNEL—RicHaRD’s LANDING.—LIGHT ON WHARF.— ince the 3oth of October, igor, a light has been maintained by the government wharfinger at Richard’s Landing,: St. Joseph channel, in the district of Algoma. . The light is a fixed white light, shown from a square tubular lantern with reflector, standing upon a shelf placed on the southeasterly corner of the warehouse on the wharf: It is elevated sixteen feet above the level of the water, and should be visible three miles from all points of ap- proach. The shelf on which the lantern stands is ten feet’ high, and is painted white.

It should be visible twelve miles from all points of approach by water, but will not be yisible from the wharves in the harbor. The site is on the southeast extremity of Little Gros Cap, but this projects farther south than shown on chart No. 320, as the shore at Eagle river is visible from the site clear of the southwest extremity.

DEPARTMENT OF MARINE AND FISHERIES, Ottawa, Canada, toth April, roo2. or oo or _The St Louis. branch of the H. W. Johns-Manville Co., report having secured the, contract for Pipe Covering in the new Bank of Commerce Building, Southeast corner Broadway and Olive St.;:St. Louis, Mo. ‘The material used on all: main pipes and rivers is Asbesto-Sponge Moulded Covering, and the breachings and hot water tank will be covered with their Magnesia. |The total. cost. of the above contract will be close on to $1,000. AIR WAVES. Helmholtz showed that when a current of air warmer, and therefore lighter, was flowing above another current colder and denser the circumstances were the same as when the wind is blowing on a level surface of liquid. In both cases regular waves aré produced in the denser medium, and the waves have their crests perpendicular to the ditec- tion of the upper current, says a scientific exchange. A wind that will produce water waves one; meter long, will, in air currents differing ten degrees C. in-temperature, produce waves from two to five kilometers in length. To water waves from five to ten meters long correspond air having a length of 15 to 20 kilometers. Stch waves, whose height above the surface of the earth is.not often greater than their length, are like water waves that stir the whole mass of water from the surface to the bottom. They are very frequent, but are not visible unless the lower layers of air are saturated with moisture so that mists are formed: In such a case paralel bands of clouds are produced, ex- tending over a large portion of the sky. In a balloon as- cension Herr Emden, of Munich, was able to recognize such waves and to make such measures as to show that the mathematical theory of their formation was completely verified: or oe EASTERN FREIGHT REPORT. Messrs. Funch, Edye & Co., New York, reports the con- dition of the eastern freight market as follows: : There is no redeeming feature in the grain situation, and as the price of cereals within the last few days has ad- vanced somewhat, the prospect of steamers being chartered for full cargoes of grain seems to be as remote as ever! Some little business has been,done from the South Atlantic cotton ports, but, as previously indicated, such tonnage has been taken principally to cover old phosphate contracts. Three steamers are reported in this isswe for case oil to the east, but the vessels named simply cover old guarantees, and therefore cannot be taken as an indication of new bus- iness. There is a little better inquiry for Deal tonnage from the Bay of Fundy ports for end of this month and beginning of next month’s loading, but owners are holding for a trifle over what shippers care to offer. Our market for sail tonnage remains quiet and without any prospect of speedy improvement in the near future in consequence of the prevailing low rates for steamers. Grain to Liverpool or Glasgow or Antwerp, 3 cents; T,ondon, 3% cents; Hull, 4 cents; Bristol, 5 cents. Se MARINE PATENTS RECENTLY ISSUED. 697,442.—Row lock. Charles H.

Starin, while passing down New Haven harbor about 11 o’clock at night, near the center of the channel, which was there 800 feet wide, and at a speed of twelve knots, came into collision with the anchored schooner Gurney, and sunk her. Held, that the steamer was in fault for violation of the rule requir- ing her to keep to the right side of the channel, and be- cause she was going at a dangerous speed, in view of the known fact that it was the custom of vessels to anchor. in any part of the harbor, and that a number of vessels were then anchored therein, and further because, under the evi- dence, if she had kept a proper lookout she should have seen the schooner for a mile or more.
