It gave me a moment of exquisite satisfaction to find myself moving away from civilisation in this rude canvas canoe of a model that has served primitive races since men first went to sea. ↗
My training was that you fill in the canvas where it needs colour and polishing. You start with the words on the first night and keep adding bits of business. ↗
One can see that a canvas is six feet by eight feet, say, quite accurately. But you can spend two minutes and think it's five, or thirty seconds and it's just a different bed for activities there. ↗
