Owing to the great difficulty attending the cultivation of foreign varieties as a field crop for market, the attention of fruit growers has been turned to the improvement of our hardy, native raspberries, of which there are two distinct species: the Rubus Occidentals, which is propagated by the top end of the canes bending over and striking root in the ground, forming a new plant, which in turn sends out shoots reaching still further from the original stock, and thus in a migratory manner soon spreads over a considerable space of land.

The Purple Cane and Ellisdale are of this order, and the Catawissa to some extent; the White, Yellow or Golden Cap, Golden Thornless, and Cream raspberries, also the different varieties of the Black Caps, such as the Doolittle, Miami, McCormic or Mammoth Cluster, Davison's Thornless, Seneca, Garden, Great Western, Hamilton, Yosemite, Ohio, Canada, and Lum's Everbearing, and many others of less value.

I have not met with an English variety grown from tips, nor a black raspberry grown from suckers.
