UV. A brief Account of the Mineral Productions of Shrop- 

 shire. By Joseph PLYMLiiv, A.M. Archdeacon of Salop, 

 and Honorary Member of the Board of Agriculture. 

 [Continued from p. 208.] 



Dr. Townson, in his Tracts, p. 166, has given the strata 

 of two ether pits in this district, and has added to the col- 

 liers' names f;)r the different measures his own definition of 

 each. He ohscrves, that " annually ahout 260,000 tons ot' 

 coal are raisol in this district ;" a very large proportion of 

 which are consumed in the adjacent iron-works, I presume; 

 for I have understood, that in the Ketley iron-works they use 

 at least six ton of coal out of every seven they raise. What f 

 have called the collieries of the eastern district, comprehend 

 pits on hotli sides the river Severn. The veins of coal in 

 this district are equal in thickness, I believe, to most in 

 this county, but very inferior to those of the Staffordshire 

 works, from 15 to 20 miles east of these, where, I have 

 been told, there is a bed of coal measuring 13 yards, or 

 more. The next coal-works to be mentioned are those of 

 the Clee Hill, from 20 to 30 njilos south of those we have 

 been describing*. Collieries, indeed, are now workuig at 

 Eillingsley, connecting them, in some measure, by their 

 situation : and again, west of the eastern coal district, pits 

 have been lately sunk with success. I am indebted to Dr.^ 

 Townson's Tracts, before quoted, for the following lists of 

 the strata in tv^o of the Clee Hill collieries.
