ON THE CIRCULATION OF UNDEEGEOUND WATERS. 237 



Boring ceased 240 feet from the surface. Water was found in the 

 lower part of the marlstone, but not in great quantity. An increased 

 quantity was found in each of the three bands of rock subsequently per- 

 forated. The water-level stands in the bore about 6 feet above the bottom 

 of the marlstone.

1. Atcham workhouse well, near Shrewsbury, la. A bore-hole was put down in 

 1884. 2. 206 feet. 3. 60 feet in depth; 4 feet in diameter; 181 feet; cased with 

 4-inch tubes. 3a. No driftway. 4. 54 feet ; the water level is only reduced about 

 6 inches in affording the supply required. The ordinary water level is quickly re- 

 stored. 4a. The water stands about 12 inches higher in well since the bore-hole 

 was put down. 5. The average quantity pumped is about 10,000 gallons daily. The 

 full yielding power of the well and bore-hole has not been tested. 6. Water level 

 does not vary since bore-hole was put down. 7. Not affected by local rains. About 

 15 feet higher than the normal summer level of Severn, which is situated about | 

 mile from the site of well. 8. Water of very good quality ; no recent analysis has 

 been taken. 9. No record of strata pierced by the well. 



Section of Boring. 



60 to 80 feet— sand. 



80 to 124 „ — sand and gravel. 

 124 to 152 „ —coarse gravel sand with flint. 

 152 to 210 „ — grey sand and gravel. 

 210 to 214 „ — red sandstone. 

 214 to 230 „ —marl. 



9a. Sand and gravel beds. lO. II. The well is cased with brickwork through- 

 out. 12. No. 13. No. 14. No. 15. No. 16. The bore-hole was carried 

 through 2i" tubes placed within the 4'' tubes to the depth of 230 feet. The inner 

 tubes were withdrawn, as an ample supply was obtained at the depth of 181 feet.
