Permit me to direct the attention of those who have the requisite means and skill, to the wide field open to them of improving our native Heaths by hybridising them with the Cape species, more particularly with some of the free-growing sorts. Could the hardiness of the one be combined with the habit and bloom of the other, what beautiful objects would be the result! The greenhouse, or rather frame varieties will bear a few degrees of frost without injury; there is, therefore, every probability that the seedlings of even the first cross would prove quite hardy, and those of a second would certainly be so. The time is at hand for trying the experiment, and the fortunate raiser of any thing good would be amply repaid by the pleasure he would experience in his new progeny. C.
