The tubing was withdrawn to 130 feet and the well finished at 150 
feet iu the gravels of the base of the Matawan formation. This water 
was also noted in the Maple Shade and other wells. It is suggested 
that if the boring had been continued a short distance farther the 
water-bearing coarse beds at the base of the Earitan formation would 
have been reached and a further supply of water found in them. 1
