2 J. F. Kemp — The Storm King Crossing 



proving that the bed-rock granite of the Hudson at the Storm 

 King Crossing was more than 76S ft. from the surface. "We 

 did know, however, that 675 ft. to the west the rock had been 

 found at a little over 500 ft. and 675 ft. to the east it was 

 encountered at 450 ft. below the surface of the river. The 

 general appearance of the scows with the drills and the cross- 

 section of the crossing itself are illustrated in figs. 1 and 2.

Fearing a failure to reach bed-rock from the river, the 

 chief engineer, Mr. J. Waldo Smith, had determined to 

 explore the crossing in a more dependable way. Shafts had 

 meantime been started on each side of the river. In them at 

 281 ft. below the surface on the east bank and 251 ft. on the 

 west, chambers were excavated on the sides towards the river 

 and diamond drills were set up when sufficient clearance had 

 been afforded to withdraw the tubes and the core-barrels. At 

 first, the drills were pointed downward from each side so that 

 they would cross at 1500 ft. below the surface of the river. 

 Ingenious devices had already been prepared so that by filling
