Some Plants of Dativers and Wenham. 293 



is not a little remarkable, that no account has ever been given 

 of the occurrence of Vaccinium Vitis Id^^a in any other part 

 of Massachusetts, which, if existent, seems to have never 

 fallen under the eye of the botanist. 



Leaving so pleasant a spot, our attention was next directed 

 to a secluded sheet of water, called Cedar Pond, on the mar- 

 gin of which the elegant Andromeda polifolia L. {^Rosemary- 

 leaved Andromeda') luxuriates. This graceful shrub was 

 just passing out of flower, so that no good specimens in that 

 condition could be obtained. Mr. Emerson informs us 

 {Rejyort, p. 372) that " it was for this modest and delicate 

 plant Linnaeus selected the poetical name of the genus." I 

 would refer the reader to the extract Mr. E. makes from 

 Linnseus's " Tour i?i Lapland,^' as well as to a description 

 of the plant from Mr. E.'s pen. A belt of these floral water 

 nymphs encircled the little lake, mingled with the rich flow- 

 ers of the Side-saddle flower, (Sarracenia purpurea,) which 

 were in their perfection. As we turned our steps from this 

 vicinity, which cost the more adventurous a wet foot and a 

 plunge-bath over boots, I noticed, on the trunks of the white 

 cedar, (Cupressusthuyoides,) several interesting lichens, espe- 

 cially the Cetraria juniperina, var. virescens Tuckerm. in fine 

 condition. Hypnum Blandovu occurred on the soil beneath 

 the trees, and pools of standing water, secured from speedy 

 evaporation by the abundant growth of several kinds of 

 sphagnum, afforded subjects of infusorial life in its many 

 forms. We were assured by Mr. Fowler, that Kalm^'a glauca 

 had been gathered by him in this region, which I should 

 deem favorable to its growth. 



From Cedar Pond, and its floral treasures, we proceeded 

 to another and larger expanse of water, which, like the 

 locality of Andromeda, occurs in Wenham, and known as 

 Pleasant Pond, affords, on its borders, several curious plants. 

 This pleasant little lake is happy in its name, for nature 

 seems to have set it like a jewel amid emerald woods and 

 gently swelling hills. From one of these elevations, covered 

 with old hemlocks, (^^bies canadensis, M.) we could dis- 

 cern the village of Wenham in the distance ; while the rat- 

 tling of the steam car announced that busy art was not far 

 from us, bearing, through these green woods and plashy-
