The opening on Mackey hill is 1 mile long and extends part 

 way around the hill. The bed of stone is 10 to 12 feet thick, 

 with a top ranging from 12 to 35 feet in thickness. The top is 

 entirely shale, which when stripped has not been disposed of 

 well, as the quarries are badly blocked in places with rubbish. 

 The stone is rather fine grained, of good blue color and reedy. 

 The lifts are very heav^^, 10'' to 21''. The top lifts do not split 

 well, but the lower ones do. The ledge dips to the south and 

 west, and the water, following the dip, collects at the southern 

 end, where it is removed by siphons. A number of firms are 

 quarrying on the ledge, and many have hand derricks in use. 

 The side seams and head-offs are all tight, sometimes requiring 

 blasting in lower lifts. The product is edge stone and " rock," 

 which is hauled to High Falls on the canal.

To the west of the northern part of this main range of quar- 

 ries, viz west of the Quarryville, Fish Creek and Highwoods dis- 

 tricts, the ledges of stone are terraced one above another, form- 

 ing as it were the foothills of the Catskill mountains. A num- 

 ber of quarries have been opened in these ledges, but only a few 

 are worked at present. The stone is of poor quality, not evenly
