The measures to be taken in order to as certain tho seat, and the exact nature, of the damage in connection with the embank ment of the reservoir of tho Water Works Company, have now been resolved upon ; a plan having been submitted by Mr M'Gregor, C.X, to the directors, at a special mooting held yesterday afternoon, and having been approved of. Aswo hftveucvcral timesstated. there was, after the first few d.i}'B of the leak, no doubt that it originated in a. fracture of ono of the pipes through the embankment. An ingenious plan was adopted, in order to a»cer tain as nearly aa possible tho point of the fracture. It was known to be within the embankment ; but its tjosition relatively to the puddle-wall, if it eo\ild be ascertained, would decide the nature of the remedial works to be undertaken. The supply pipe, from the bottom of the valve-tower to the outer edge of the embankment, la nearly 250 ft long. It is of I4in diameter. The plan resolved upon for examining it, was to get a boy to allow himself to-be hauled through the pipe, taking a lantern with him, ao that he might bo able to see the fracture. To gut the first string through, as the initiation of haulage power, some young puppies were put ut one cud of the pipe, and their mother at the other end. She had some twine fastened round her neck ; and as she speedily crept away to her yelping young ones, she carried the lino with her. Afterwards, tho rigging up of the necessary apparatus was easy. One lad volunteered to, be pulled through on the truck or slcdgo, but hh heart failed him after he had traversed a short distance, and he was speedily brought back to daylight. On a subsequent day, William Saarland, a

j lad empl. yod by Messrs Dick and Fleming, wo believe, volunteered. Like his pre decessor, he had a rope fastened round him, in addition to the blcdgc rope ; and ho also carried a lino, which ho was instructed ■to loose, vh'n he was at the point of the fracture. Shirland entered the |tjj>o frovn the well-tower cn-1, carrying his light, and secured as wo have stated. Ifo saw the fracture, loosed his measuring line, and tkw speedily ran out at the foot of the embank ment.
