leaves are disting-uishable from those of the early low form, as 

 shown in the key and the accompanying cut, by being larger and 

 broader, smooth with entire margins, pale green above and 

 whiter underneath. The fruit is a large blue berry with much 

 bloom and excellent flavor. It ripens in July and August along 

 with the late high berries and so contributes a part of the later 

 market berries. It deserves the attention of anyone attempting 

 blueberry culture, though it is not so promising as the two pre- 

 viously commended. 



the: mountain blueberries. 



Anyone visiting the higher mountain summits, especially 

 Mansfield, in midsummer may find the following three mountain 

 blueberries. All are dwarfs, but a few inches in height, matted 

 in the moss of boggy depressions along with the bearberry and 

 mountain cranberry. The fruits of all are sweet and edible. 



The narrow-leaved variety of the early dwarf blueberry al- 

 ready described (V. pennsylvanicum var. angustifolium Gray) 

 is found on Mansfield and Camel's Hump, only a few inches in 

 height and with narrower and lanceolate, minutely-toothed leaves, 

 and berries bluish-black with bloom. 



The bog bilberry, {V. tiliginosum L.) forms low tufts with 

 the preceding and has been found at lower altitudes. It is 

 characterized by the shorter rounded leaves with an entire mar- 

 gin, which show a dull bluish cast above, and are paler and 

 slightly pubescent beneath. The fruit is blue-black with bloom. 



The dwarf bilberry (F. caespitosum Michx) completes the 

 arctic trio. Its leaves are larger than those of either of the others, 

 minutely toothed, yellow green, smooth and shining on both 

 sides. Its berries are larger and blue with bloom. This is at 

 home on "the chin," the highest point of Mount Mansfield, but 

 has also been located in Newfane and Washington.
