Berkshire, where it is now frequent. He gives it from Maiden and 
Cambridge and calls it " a native of England." He says of Trifolium 
officinale and TrifoVnm albwu {MelUotvs officinalis and alba), p. 06, 
"The yellow-flowered and the white, both finely scented are often 
cultivated in gardens. The white is sparingly naturalized in some 
places." Both are now naturalized, the white commonly, and the 
yellow frequently. The Pitcher Plant, Dewey calls the Side-saddle 
Flower, " from the resemblance in shape and position of its curved and 
hollow leaf to the horn of a side-saddle." The name with the equip- 
ment is now practically unknown. He says nothing about the insec- 
tivorous habits of the plant. Agrosicmma Githago, now rare, he calls, 
p. 87, "a well known weed of wheat fields." CcraMium vulgatuvi he 
speaks of, p. 89, as of " little consequence except as yielding seed for 
the food of small birds." Pi/rola (now Moneses) imiflera, common in 
pine woods, he says is "found near Salem by Mr. Oakes." The 
Canada Thistle {Cirsium arvcnse) had already become a menace, but 
Cirsium pvmilum he says, has been "found near Boston." Joe-Pye- 
Weed {FAipatoriuvi purpurcuvi) is "said to have been recommended 
to the whites by an Indian of the name." The Shakers "manufac- 
tured the heads and leaves of Gnaphalinm margaritaceum [Anaphalis 
margaritacea] into mattresses, and which are said to be pleasant and 
healthful." Rudbcckia kirta is not mentioned. Of Prunella, of which 
the popular name in the books is Heal-all, Dewey says, " Not used to 
heal anything." Galcopsis Tctrahit, he says, has "sprung up from 
straw thrown out from crates of crockery." Thymus Scrpyllum, now 
common in the central towns of the County, he says is " cultivated in 
gardens and naturalized in a few places, formerly used in cookery." 
Diantkm Armeria, Saponana officinalis, Rumex Acetosclla, Planfago 
major, Arctmm minvs, Leontodon taraxacum (= Taraxacum officinale), 
Tanacetum, Inula, Tussilago, Veronica arwnsis, T. agresiis, and T . 
serpyllifolia had all become naturalized in Dewey's time. 
Shortly after Dewey had become established as a professor at 
Williams College, A. A. Eaton, though not a member of the faculty, 
gave a series of lectures at the college on botany which created an 
unusual interest among the students and even in the community. 
Eaton, was born in Chatham, New York, a few miles from the border 
of Berkshire County in 1776; he graduated from Williams College in 
1799. In 1817 he lectured on botany to enthusiastic classes at Wil- 
liams College, and at their request pubHshed the first edition of his
