GREY BAR

[to the editor,] Sir,—A few facts on the above subject may be appreciated by those concerned, in lieu of the erroneous paragraph in your last night’s issue. “The Kaimai it is understood, touched and stuck momentarily, swinging around dangerously on her keel until a swell lifted her off and she was able to make way again.” The first half dozen words are correct and the remainder erroneous; for she did not stop or deviate from her course. Now for the subject matter. From the recent rain we experienced at the maximum a four knot surface current which according to the accepted practice would give 2.82 knots mean, but not tp be too technical will say 3 knots

mean current; and the latter under adverse weather conditions —rough sea, etc., —scoured out over four feet additional depth on the line of bar beacons, which I contend demonstrates the efficacy of the present slight extension of the North breakwater, and when the contemplated raising of the lower training wall is completed should make any increase of current above normal very effective. Under the old conditions the current, especially with the strorig northerly set, would have sneaked around the north tip and not have touched the shoaling. Yours etc., — F. W. COX, Harbourmaster.
