A library is an important design tool. A library can be as simple as a folder stuffed with pictures of everything you ever saw or read that you liked. I find books irresistible, and I have collected them as long as I have gardened. They expose me to other people and places. What I see when I read becomes a part of what I bring to my work. It reminds me that I am part of a community of a certain sort. Would that someday I could write one essay the caliber of those written by Henry Mitchell. The long time garden writer for the Washington Post, until his death in 1993; his books I read over and over again. To follow is one of my favorite essays by him-this spring it seems especially timely. His book, The Essential Earthman, is a much have garden tool.
