works east and west instead of north and south. It is 

 coarser grained. The color is not so good, tending toward a 

 gray. It is less liable to slaking, and fewer reeds are found in 

 the lifts. 



The ledges of stone are more pockety than the Ulster county 

 stone. The A'ertical jointing is more irregular, specially the 

 east and west joints. Less shale is found in the stripping, and 

 the dip is not persistent in any cue direction. 



The quarries have nearly all been opened high up on the hills; 

 so the drainage is natural. " Black jack " and " sap " are 

 peculiarities of these quarries alone. " Sap " rock is the dis- 

 colored greenish gray stone which is near the joints. The dis 

 coloration extends into the bed from 1 to 3 feet on each side of 

 the joint. " Black jack " is a soft, claylike material, whict 

 occurs in the ledges in lens-shaped forms. It crumbles under 

 the hand and contains a great deal of iron. It is due to an 

 alteration of the rock, and when occurring may, as the quarr^^- 

 men say, " eat out " the whole bed and ruin the quarry. 



The prices paid the quarrymen are much lower than at the 

 docks on the Hudson, because of the difference in cost of trans 

 portation to market. But the proximity of the railroads les 

 sens the cartage charges. 



In the isolated districts business seems to be in a fair con 

 dition, with an active demand at Oxford.
