A correspondent sends us an extract from a letter by Wm. Izzard Bull, apparently from some part of the far South. The letter is sent it seems for some opinion on the points referred to. It is said that varieties in a forest never intermix. Thus if a wood contains black oak, white oak, and red oak, the pollen of one species will not affect the other. Each produces seed which reproduces its own kind. This is sufficiently correct to be the rule. Some botanists believe that hybrid trees occasionally occur. Another point is that the Live Oak is a misnomer. We never knew certainly why the tree was called "Live Oak." This correspondent believes it was from its evergreen character. He does not regard it as a true evergreen. The leaves fall off as the new ones come. But our definition of evergreen is one which always has some green leaves on it. It is the tree we are to regard as an evergreen, not the leaves.

Of the Wax myrtle - Myrica cerifera - it is said our grandmothers made candles from the wax in the seed. It might be added that our fathers and mothers did the same thing in Eastern New Jersey, if even some of our broth era and sisters do not to this day, though perhaps coal oil has by this time found out the last wax berryman. We are much obliged to our correspondent for Mr. Bull's interesting letter.
