with down to 416 feet 6 J inches was about 75 gallons per hour. 

 Below this a bed of soft porous sandstone was passed through, 

 having a- thickness of 22 feet 1 -^ inches. The base of this bed 

 was, therefore, at a depth of 438 feet 8 inches, and water made 

 in the shaft at this level, at the rate of 200 gallons per hour, thus 

 bringing the total inflow up to 275 gallons per hour. At a depth 

 of 442 feet, where a " walling curb " was seated, a " water ring" 

 or " garland " was also put in. In this all the water was collected 

 and thence led down one side of the shaft in a 2" diameter wrought 

 iron pipe. The same amount of water, viz. 275 gallons per hour, 

 continued to a depth of 607 feet, when in a bed of hard, greyish- 

 white, false bedded, and very friable sandstone, a feeder of water 

 accompanied by gas was met with, the inflow of water being at 

 the rate of 170 gallons per hour, thus making the total inflow 

 445 gallons per hour. The gas, which evidently came from a bed 

 of clay shale which was struck three feet below the feeder, took 

 fire when a light was applied. At a depth of 672 feet, in a bed 

 of clay shale, soft and jointed and one foot thick, another small 

 feeder of water was struck which raised the total inflow to 463 

 gallons per hour. At a depth of 690 feet, the sinking being then 

 in a thick bed of greyish-white sandstone, false bedded and friable, 

 the water increased to 597 gallons per hour, and in the same bed 

 of rock, at a depth of 700 feet, the total inflow still further 

 increased to 654 gallons per hour. This bed of sandstone was 43 

 feet 10 inches thick, the top being 676 feet from the surface (top 

 of brick walling) and the bottom 719 feet 10 inches. At a depth 

 of 720 feet the water began to decrease, the total inflow being at 

 the rate of 550 gallons per hour, and at the 750 feet level it had 

 still further decreased to 511 gallons per hour. At the 768 feet 

 level another "water ring" was put in, from which the whole of 

 the water was led down the shaft in two inch diameter wrought 

 iron pipes. When a depth of 774 feet was reached it was found 

 that the inflow of water had still further decreased, the total 

 amount being about 502 gallons per hour. Thence, down to the 

 bottom of the shaft, the average inflow has ranged from 480 to 

 510 gallons per hour.
