The Carolina mountains have a great variety of huckleberries (Vaccin-iam and Gaylussacia) ripening in succession from July to September. When we first met with acres of those bushes, in September, covered with large delicious fruit, the temptation was so great that we partook rather freely, expecting to pay the penalty of over-indulgence, but were happily disappointed. Judging from the experience of others and our own on many occasions; those berries are remarkably healthy. Most of them were larger than any we ever saw at the South. The Vaccinium Constablei of Gray, which sometimes grows ten. or fifteen feet high (on Shining Bock), was covered with ripe fruit as late as the middle of October. There are several species of the huckleberry which are worthy of cultivation. The common high blackberry (Rubus vilioaus) is often found in dense patches on and near the mountain tops, with its stem's smooth, and destitute of prickles. This rule is constant. We do not remember to have met with an exception.
The same species growing in the valleys has its stems armed with prickles." - Ibid.
A huckleberry bush or two, either of the upland or swamp species, should be in every garden. They are seldom cultivated, but are worthy of far more attention than has been heretofore bestowed upon any of the native species.
