WEATHER FORECAST FOR FEBRUARY, 1879. THE CURRENTS OR TENDENCY OF THE AIR OVER THE BRITISH ISLANDS FOR THE MONTH OF FEBRUARY, 1879. Date. Feb. NOTE.-Current due to the Sun at first S. Easterly; then conflicting Currents or Calms; and, towards end of month, S. Westerly. 1. The Table indicates REMARKS. Strong Westerly tendency from the 1st to the 5th inclusive. 2. An examination of past weather would lead us to expect that From the 3rd to the 11th would be the stormiest period. Temperature probably low, as the Northerly and Easterly currents are of the longest duration. 3. The Westerly and Easterly currents doubtless overlap each other to some extent, and if equally balanced will produce these calms, with their attendants, fogs and mist; but if unequally, storms. The change from the Westerly to the Easterly currents, stated in the Forecast as occurring about the 11th or 12th, will probably take place earlier in the North than in the South, while on the other hand the change from the Easterly to the Westerly, occurring about the 20th or 21st, will take place earlier in the South. 4. Whilst the Moon is going South, or from the 3rd to the 15th, the normal changes of wind are: East, backing to North and West, calm, changing at once to East, backing to North, and so on. Fine weather during this period, with winds Westerly in the North, drawing round through North to Easterly, in the South. Again, whilst the Moon is coming North, or from the 16th February to the 2nd of March, the normal changes are: West, backing to South and East, calm; changing at once to West backing to South, and so on. Fine weather during this period, with winds Easterly in the South, drawing through South to Westerly in the North. D. D. WATCH AND WATCH.-In reference to the publication in our January number of the opinions held at certain ports on this subject, the statement as regards Hull, on page 87, requires modification, and should run as follows:-"That there appears to be no objection, legally or otherwise, to a competent third mate holding a second or higher grade certificate, taking charge of a watch or of the bridge in a steamship, if the Master approve the same." QUICK PASSAGE FROM SYDNEY TO SAN FRANCISCO.-On a recent trip the steamer, City of Sydney, 3,000 tons, Captain Dearborn, made the fastest steaming time on record between Sydney and San Francisco. She was just 628 hours (26 days, 4 hours) en route, including stoppages, and landed the mails 2 days ahead of time. -New York Maritime Register. A.M. TIDE TABLES FOR FEBRUARY, 1879.
