Three years after his graduation, he was appointed assistant to his former instructor, and two years later sailed for the South Seas as mineralogist and geologist of the United States exploring expedition commanded by Charles Wilkes. He was absent for three years and spent thirteen more in studying and classifying the material he had collected. He then resumed his work at Yale, succeeding Prof.
What every-day experience or the test of fire had taught a prospector, in delving among the rocks, was all there was of it. Linnæus was getting things upon a scientific basis, when he met and fell in love with the handsome daughter of Dr. Moræus. The young people would marry, but the doctor, though he liked the mineralogist, would not hear of it till he could support a wife.
We have as yet no clue to the laws by which this distribution of volcanic elements in the formation of the earth is regulated; but there is found to be a difference in the crystals of the Plutonic rocks belonging to different ages, which, when fully understood, enables us to determine the age of any Plutonic rock by its mode of crystallization; so that the mineralogist will as readily tell you by its crystals whether a bit of stone of igneous origin belongs to this or that period of the world's history, as the palaeontologist will tell you by its fossils whether a piece of rock of aqueous origin belongs to the Silurian or Devonian or Carboniferous deposits.
The remotest discoveries of the chemist, the botanist, or mineralogist will be as proper objects of the poet's art as any upon which it can be employed, if the time should ever come when these things shall be familiar to us, and the relations under which they are contemplated by the followers of these respective sciences shall be manifestly and palpably material to us as enjoying and suffering beings.
"The most beautiful specimen of amethyst I ever beheld!" cried a mineralogist enthusiastically, taking it from De Beauxchamps's hand. "What was the rock?" "Unfortunately, I am no mineralogist," replied the Frenchman, "and I cannot tell you, but these gems were abundant. I could have almost filled the boat if I had had time.
As it would have been a pity to lose a whole day, we hired a boat and started at 2 A.M., which gave us the double advantage of avoiding the heat, and enjoying a splendid bit of the river ten miles from the town. The neighborhood of Jubblepore is charming; and besides, both a geologist and a mineralogist would find here the richest field for scientific researches.
But when a sailor fell overboard we were told what an excellent and laborious man he was, and how much he was regretted; the death of Bernier called forth an appropriate sentence of eulogy; when Depuch, the mineralogist died, we were properly informed that he was as much esteemed for his modesty and the goodness of his heart as for the extent and variety of his knowledge.
"It can show those who remember him as he was that Grenfell the assayer and mineralogist can still look round a mineral basin and tell just where the gold should be." Weston was no geologist, but he had seen enough of it to recognize that prospecting is an art.
Brooks was a college graduate, a civil engineer, and a mineralogist, and believed he had great advantages in searching for a mine, but, as has been indicated, thus far their tramp and search had been a dead failure. "I'll stick with you," said Desmond. "No, lad, you must go back." "I swear I will not; I like this life, and remember, we have gathered some wash dust and we may gather more.
Canary has never been visited by a learned mineralogist; yet this island is so much the more worthy of observation, as the physiognomy of its mountains, disposed in parallel chains, appeared to me to differ entirely from that of the summits of Lancerota and Teneriffe.
