The Kalmias afford some of the most splendid ornaments of the forest The leaves 

 are all poisonous; nevertheless some animals, it is said, eat them with impunity, and 

 that too to such an extent as to make their flesh poisonous to man, it becoming so 

 Impregnated with the poison of tho leaves. This has proved the case with partridges 

 after a winter of deep snows among the mountains, when the bird is compelled to 

 live almost entirely on these leaves. An ointment made from the leaves has been 

 used in cases of scald-head, itch, and other cutaneous affections. Care should be had 

 in its use, lest the system should be injuriously affected by the cutaneous absorption 

 of the poison.
