tribe of grasses, canes and reeds. Here too we find the first 

 created fruit-tree yielding fruit to be the ancient palm. No 

 records but the geological could ever have brought to our 

 knowledge the known truth, that no cauline or dicotyledonous 

 plants were created, until all rock strata were finished ; nor 

 that man was created later than cauline plants.

 period of time which is far beyond the highest recorded limits 

 of antiquity. This enrapturing pursuit is within the reach of 

 none but the geologist. 



Geology teaches us that minerals which are associated in Sd.fn sear- 

 one district of country are associated in the same order in all useful min- 

 other districts. Hence the experience of the miner and the 

 quarry-man in any country may be applied in searching for 

 useful minerals in all countries. But here the aid of the sci- 

 entific geologist is necessary ; for geology is the true science 

 of mining. As in all other cases of the kind, the facts which 

 accident presents to the artist, must be collected and general- 

 ized by the man of science ; and then presented to all artists 

 of the same profession. For example, the discoveries of gold 

 in the talcose slate of the Carolinas, will serve as an index to 

 the miner, pointing to the whole range of talcose slate from 

 Georgia to Canada, by way of New- York and the Green 

 Mountains of Vermont, 



From the general composition and character of every kind sdjnjudg- 

 of detritus, we are enabled to judge of the fertility of soils

and to apply correctives m cases of barrenness. For exam- soils, 

 pie, whenever we find marine sand, which is now known to 

 be a very extensive stratum, we can always find the marley 

 clay beneath it. This will induce the agriculturist to apply 

 an efiicient corrective for improving his barren sands, by rais- 

 ing the marley clay from pits, and applying it to the suirface 

 as his situation may afford the means.
