It can easily be believed in my wanderings through America that I took good care to have time to go for a walk of some sort every day. Yes, I have "gone for walks" in every state in the Union, except those of South Dakota, Arizona, Nevada, Wyoming, Washington and Utah!... (Autobiography)

My chief difficulty in San Francisco is to find anywhere to walk. Finally I discovered a quiet Cemetery where the dead were more sympathetic than usual; because most of them, like myself, were foreigners from the old lands.
But this week I found another escape from the city's pavements among the hills wh. I reached by tram. There were a few rocks on these hills — and I actually helped an old woman driving home a recalcitrant black-and-white heifer! and I could see the distant Pacific into which the sun was going down in a shower of rain; for the rainy season has begun; and the hills are going soon to turn green again...

As usual I walked a little too far this afternoon trying to find some way out into the country, all red-clay cotton-fields pine woods & oak woods & muddy steep-banked rivers but I couldn't get further than the endless shanties of colored people wh. seemed to stretch on into the sunset, delapidated ramshackle and devil-may-care, dusky faces and hearts nonchalent & African under their American clothes.

For few people can walking have played such a central part in their lives as for John Cowper Powys. Wordsworth could refrain from a walk, but Powys could not. Towards the latter half of the nineteeth century walking had become a recreation of the upper-classes. Powys would seem to fit into that category. He did not regard walking as work, yet even a cursory glance at Powys's life reveals that walking for him was so much more than recreation and when seen in the light of Wallace's discovery of peripatetic its true role and significance become immediately clearer. Walking for Powys was therapeutic, both physically and mentally. It enabled him to cope with the pressures and difficulties of life since it allowed him to enjoy the ordinary pleasures each day had to offer, its sensations, even ecstasies, especially when met with in 'humanized Nature'. What is more, through these sensations, he built up layer upon layer of associative memories that he felt linked him to his relations, to his ancestors and indeed to the whole of creation, past and present.

Powys, because of his special use of memory, made all of his walking excursive, even those nomadic wanderings of his as a lecturer in the United States. He integrated all his new experiences and sensations into the store brought from England. So once settled into an extremely regular regime of daily excursive walking in upstate New York he was able to build for himself a home base that was not foreign to his creative needs but on the contrary proved to be a precipitate in the writing of his very English, West country novels and his autobiography.
