PENSYLVANIA 13 



The collection he has begun of domestic minerals is 

 indeed small as yet, but none the less remarkable, since 

 a better is nowhere to be found. Among its contents 

 are : Shorl, from the neighborhood of Lancaster, 

 sprinkled in quartz and sand-stones. Carnelians, and 

 other colored pebbles, from the Conestoga. Terebratu- 

 lites, from the Middletown region, which are taken by 

 the country-people to be petrified hickory-nuts. Beau- 

 tiful Lead-spar from Pequea Creek in Pensylvania; 

 the ton of this ore gave 1500 pounds of lead, and a few 

 ounces of silver besides ; the superintendent of the mine 

 asked of the share-owners a 13th part of the outcome as 

 his proportion for services rendered, which being re- 

 fused he filled up the mine, and the work stopped. Pit- 

 coals and Slate of various quality, from the Susque- 

 hannah. Whet-stones and Touch-stones, of which 

 the gold-smiths make good use, from near-by Lan- 

 caster. Hog-stones, Smoke-topaz, fine crystals, cu- 

 bical marcasite, eight-sided crystalline iron-ore 

 {Miner a ferri 8-edra. Cronst.), black chalk from this 

 region; Ringing-stone (Saxum tinnitans L.) from 

 Potts-grove ; Soap-stones, and other related soft 

 stones, from the South Mountain ; brown-flecked 

 Marble, a porphyritic stone with shorl, divers clay 

 and marl-earths from the country round about, and 

 many other ores and stones, mention of which would 

 be tedious. 



I got to know another worthy man of great good 

 sense in Mr. William Henry (Judge of the common 

 pleas). He showed me a tolerably pure rock-crystal, 

 of at least 5 pounds' weight, from this region ; lead-ore 

 from the Juniata, which contains calamine as well ; in 

 the flues beneath which the lead is melted zinc-flowers
