52 Pretz: FLorA oF LEHIGH COUNTY, PENNSYLVANIA 
because Lehigh County was erected from Northampton on March 
6, 1812, and enlarged in 1852 and 1859. <A collection made by C. 
F. Beitel (approximately 1830-1865) is a part of the herbarium 
at Muhlenberg College, but it gives no dates or localities, though 
presumably partly collected in this region. There is a record 
of Elias Durand (1794-1873), the Philadelphia botanist, having 
botanized along the Lehigh River in the county. Among the 
Moravians there have always been some persons who were inter- 
ested in.botany. Among those who have visited the county in 
their collecting may be mentioned Rev. Lewis David de Schweinitz 
in the fungi, F. A. Wolle in fresh water algae, and Eugene A. Rau 
in the bryophytes. Mr. Rau’s collections in the county have 
however not been confined to the bryophytes but include inter- 
esting records in the pteridophytes and spermatophytes. Dr. 
A. L. Huebener, of the Moravian Seminary, also collected in the 
region. His collection is a part of the Seminary herbarium. 
Prof. T. C. Porter also visited the county, though his list shows few 
records for the county. Dr. A. F. K. Krout, of Glenolden, Pa., 
resided in the Borough of Coplay in the county from 1869 to 1892 
and refers to Capt. P. A. Lantz, of Saegersville, in the county as 
a coworker at the time. Dr. Krout collected actively during his 
residence in the county, and his collection, including some from 
the collection of Capt. Lantz, is now a part of the herbarium of 
the Philadelphia Botanical Club at the Academy of Natural 
Sciences at Philadelphia. Until his death several years ago, 
Dr. William Herbst, of Trexlertown, collected chiefly in the fungi. 
For severa years, during Dr. Philip Dowell’s connection with 
Muhlenberg College, a large part of his leisure was given to col- 
lecting in the county. The writer acknowledges with pleasure 
his great indebtedness for his knowledge of field botany, especially 
in the pteridophytes, to Dr. Dowell, with whom he was usually 
associated on these excursions. Mr. D. W. Hamm, a student at 
that time and now a teacher, also an associate in field excursions, 
has retained his interest in the study. Mr. C. N. Lochman, who 
is associated in business with Mr. E. A. Rau in Bethlehem, is an 
active field worker who has frequently botanized within the county. 
Mr. C. C. Bachman is an active field botanist and has collected 
considerably in the county. Other botanists of ad joining counties
