Fall Back: Working in all sections from Maryland north they developed five different versions of the Windsor by 1750. In addition to the low-back of Philadelphia provenance, there were the comb-back, the bow-back, fan-back and loop-back. Another version, the arch-back, appeared about 1785, followed after 1800 by the rod-back and arrow-back. Then some 40 years later, there was a survival type, now known as the firehouse Windsor. With its low, horseshoe-shaped arm it reverted to the general lines of the first low-back Philadelphia :hair.
It is natural, then, that two different migratory movements should be observable in the Rocky Mountains; one the regular seasonal movement southward in the fall back and back in the spring, affecting chiefly those birds tha"t live at the base of the range, or near it; and another movement, which is regularly made by many animal?, upward to the cooler and fresher pastures in the summer, and back to the less snowy and more sheltered dells near the base of the mountains as winter approaches. This vertical migration is very well understood in the case of the game, and the paths which the animals follow are often distinct.
The large-flowered clematis are divided into several groups according to their parentage. These groups are Florida, flowering mainly in early and mid-summer; Jackmanii, flowering mainly in late summer and early fall back; Lanuginosa, flowering at different times between mid-summer and the early fall back; Patens, flowering mainly in early to mid-summer; Texensis, flowering mainly from late summer to mid-fall back and Viticella, also flowering mainly from late summer to mid-fall back. |
