NOTE.-Sun's gradients will probably make a retrograde movement during month, bringing back temporarily the Easterly current. From about the 1st to the 5th, S. Westerly ; 6th to the 21st, N. Easterly; then S. Easterly; succeeded by S. Westerly towards end of month or beginning of April.

REMARKS.
1. The Table indicates

Strong Westerly tendency from the 1st to the 5th inclusive.
Very Northerly

6th 12th
Easterly

13th 19th South Westerly,

2. Moon going South from the 3rd to the 14th.

„ coming North „ 15th „ 29th. 3. The change from the Westerly to the Easterly currents takes place about the 11th-earlier in the North; and the change from the Easterly to the Westerly about the 19th—later in the North.

4. It may be observed that the force from E. or W., or the rotatory velocity, is uniformly high during the month. This will probably render the gradients steeper, and make the rising and falling motion more rapid.

5. The stormiest period will probably be from about the 6th to the 13th.

6. It must be borne in mind that these tendencies will usually form gradients for winds at right angles to their direction; for example, a N. Westerly tendency will form gradients for S.W. wind with a falling barometer, and for N.E. wind with a rising one.

Gulf of ST. LAWRENCE. For some years past the Hon. P. Fortin, M.P. for Gaspé, Canada, has been urging the establishment of telegraphic communication from point to point across the gulf of St. Lawrence, and particularly with the islands of Anticosti and Magdalen, and that the wires should converge to one central point where a powerful steamer would be stationed in readiness to proceed out at very short notice. The object of this enterprise is to check the wrecking and pirating which are carried on by the inhabitants of some of the wild shores which border the Gulf, and to assist in opening up commerce with those parts. We learn from Mr. J. U. Gregory, the agent at Quebec for the Marine and Fisheries Department, who has recently been in London, that the advantages of such means of communication would be very great, and would tend to induce settlements and develope trade and agriculture in places which are now wild and inhospitable; besides putting an end to the wrecking business, and enabling timely aid to be given to vessels in distress. The desirability of such a scheme being carried out requires only to be made known, in order that the Canadian Government may be urged to take it up, and we trust M. Fortin's efforts will before long be crowned with

success.
