In 1875, a Massachusetts farmer, curious about the growing power of expanding apples, melons, and squashes, harnessed a squash to a weight-lifting device which had a dial like a grocer's scale to indicate the pressure exerted by the expanding fruit. As the days passed, he kept piling on counterbalancing weight; he could hardly believe his eyes when he saw his vegetables quietly exerting a lifting force of 5 thousand pounds per square inch. When nobody believed him, he set up exhibits of harnessed squashes and invited the public to come and see. The Annual Report of the Massachusetts Board of Agriculture, 1875, reported: "Many thousands of men, women, and children of all classes of society visited it. Mr. Penlow watched it day and night, making hourly observations; Professor Parker was moved to write a poem about it; Professor Seelye declared that he positively stood in awe of it."All this is very jolly. Unless perhaps I were strapped down above a stand of growing, sharpened bamboo, I am unlikely to feel the faintest queasiness either about the growth pressure of plants or their fecundity. Even when the plants get in the way of human "culture," I don't mind. When I read how many thousands of dollars a city like New York has to spend to keep underground water pipes free of ailanthus, ginko, and sycamore roots, I cannot help but give a little cheer. After all, water pipes are almost always an excellent source of water. In a town where resourcefulness and beating the system are highly prized, these primitive trees can fight city hall and win.
