If in a city we had six vacant lots available to the youngsters of a certain neighborhood for playing ball, it might be "development" to build houses on the first, and the second, and the third, and the fourth, and even the fifth, but when we build houses on the last one, we forget what houses are for.

My dog does not care where heat comes from, but he cares that it comes, and soon. Indeed he considers my ability to make it come as something magical, for when I rise in the coal black pre-dawn and kneel by the hearth to make a fire, he pushes himself blandly between me and the kindling splits I have laid in the ashes, and I must touch a match to them by poking it between his legs. Such faith , I suppose, is the kind that moves mountains.

I now suspect that just as a deer herd lives in mortal fear of its wolves, so does a mountain live in mortal fear of its deer.
