taught chemistry, geology, mineralogy, and botany, to 
boys, making with the boys very pleasant botanical 
excursions through the country round. My first sum- 
mer vacation, if I rightly remember, was in cholera 
year, the disease being very fatal in Utica. About 
the time it made its appearance in New York I 
started off from Bridgewater, taking a little country 
stage-coach down the Unadilla to Pennsylvania; vis- 
ited Carbondale and made a collection of calamites 
and fossil ferns; thence by stage-coach through the 
Wind Gap to Easton ; thence out to Bethlehem, where 
I passed a day with old Bishop Schweinitz,! gave 
him a Carex which he said was new, but I told him it 
was Carex livida, Wahl. (and I was right) ; back to 
Easton; thence up to Sussex County, N. J., collect- 
ing minerals (Franklinite, ete.) ; thence to adjacent 
Orange County, N. Y., collecting spinelles, ete., as 
well as botanizing; thence down to New York early 
in September; there I met Dr. Torrey for the first 
time, and we took a little expedition together down 
to Tom’s River in the pine barrens, and back to New 
York in a wood-sloop. 
The next year, in the spring, Dr. Torrey went to 
Europe, sent to purchase apparatus for the New York 
City University, then just established. He engaged 
me to go that summer to collect plants in the pine 
barrens of New Jersey, he to take the half of my col- 
lection, paying what would be required to defray my 
very moderate expenses in the field. I found after- 
wards that these plants went to B. D. Greene and 
his brother Copley, then abroad and full of botany ; 
1 Lewis David Schweinitz, 1780-1834; the first American who 
studied and described the fungi of the United States. He wrote also 
on other North American cryptogams and carices.
