The bulb at Wallasey Pool detracts from narrows.1" 6 tnc momentum. The straightening the wall in the manner described would improve the current and increase the momentum, inasmuch as the present irregular shores make irregular currents; those irregular currents /. M. Remiel, act upon each other and impair the general effect. If they can be made 23 June'1844 direct they are made more efficient, and consequently they will send a larger body of water up into the estuary, or at all events they will send that water up into the estuary which now runs into Wallasey Pool. I Abstraction of am as great an enemy as any one to the general question of abstracting water" water from estuaries, but there is a peculiarity in this case which takes it out of the general class of causes of the abstraction of water from estuaries. To ascertain the strength of the currents, I had accurate observa-Observations tions (with watches adjusted) at Egremont, Seacombe, Wallasey, Wood-nts? CUf side, and Tranmere, and having a fleet of boats and a steamer to attend us, we put down floats, so far submerged that the wind could have no effect upon them, in the centre of the stream and on either side, far enough from the shore to feel the strength of the current, and the floats were observed as they passed each of the lines of the sections at the above places. The distances were great enough to give as accurate a result as could be obtained by any experiment of the kind, none of them being less than 2600 feet, and the greater part from that to 3000. The mean velocity of the tide per second upon the flood from Egremont to Seacombe wa...
