- Entiat Slopes Natural Area Preserve (dnr.wa.gov)
This 1,920-acre site and its surrounding landscape are characterized by steep, rugged terrain and narrow canyons that terminate at the edge of the Columbia River. The preserve contains one of the largest known populations of Thompson’s clover, a plant that is state-listed as “threatened,” and a population of longsepal globemallow, a state-listed “sensitive” plant. The preserve, which also contains grasslands and scattered ponderosa pine and Douglas-fir, is susceptible to-and has evolved with-frequent natural fires. The rare plants at this site are adapted to this fire regime. Thompson’s clover relies on fire to remove encroaching trees and reduce competition in its habitat, while fire and heat enhance seed germination for longsepal globemallow, resulting in dramatic increases on the preserve following the most recent wildfires in 1988 and 2014.
- And, in the last place, what above all is here worthy of observation, is the generation of the animal spirits, which are like a very subtle wind, or rather a very pure and vivid flame which, continually ascending in great abundance from the heart to the brain, thence penetrates through the nerves into the muscles, and gives motion to all the members; so that to account for other parts of the blood which, as most agitated and penetrating, are the fittest to compose these spirits, proceeding towards the brain, it is not necessary to suppose any other cause, than simply, that the arteries which carry them thither proceed from the heart in the most direct lines, and that, according to the rules of Mechanics, which are the same with those of Nature, when many objects tend at once to the same point where there is not sufficient room for all, (as is the case with the parts of the blood which flow forth from the left cavity of the heart and tend towards the brain,) the weaker and less agitated parts must necessarily be driven aside from that point by the stronger which alone in this way reach it.
