of food in the seeds to myriads of birds. From its flowers bees collect 

 great quantities of honey, but it is darker coloured, and more bitter 

 than other kinds. The stems and branches in many parts of the country 

 are made into brooms, for which purpose it is cut in the autumn ; and 

 in some parts of Scotland, it is said to be the chief revenue of the 

 Highland lairds : it is the badge of the Clan Macdonnell. It forms 

 an excellent edge row to garden borders and plots, bearing clipping, 

 as well as the box; the white, and especially the double flowered 

 variety, is remarkably beautiful, each flower is much larger than 

 the common, and is like a drooping cluster of delicate miniature 

 roses. On its tender shoots and stem, the Little Dodder often establishes 

 itself, and spreads its long thread-like stems for some distance upon 

 them, having a remarkably wild appearance. The Calluna vulgaris is 

 the only known species of the genus, and is found on heaths and moors 

 in the sub-alpine districts of all parts of Europe. In some parts of 

 Tuscany we have observed the flowers sometimes as large again as 

 with us, but not otherwise difl"erent.
