Though these are not grown so generally as the other kinds of fruits, there are some who have given their attention to the subject, and succeeded in forming artificial swamps where cranberries have been cultivated with success. Wherever there is a plentiful supply of running water, with abundance of peat soil, no difficulty need be experienced in growing cranberries. The two species most worth cultivating are the English and the American.

English (Oxycoccus palustris)

This grows abundantly in bogs or swamps, in many parts of England. The fruit is the size of a pea, and the skin pale red; they have a somewhat acid flavour, and a strong acidity.

American (Oxycoccus macrocarpus)

Of this there are three varieties : -

1. Cherry Cranberry, is large, round, and of a dark red colour, resembling a small cherry.

2. Bugle Cranberry, so called from the shape being like a bugle head, long, and approaching an oval. Skin, pale, and not so deep a crimson as the other varieties.

3. Bell Cranberry, is bell-shaped, or turbinate, and of a dark coral red. This is a very large variety, and is a great favourite with American growers.
