H. G. Wells,
Floor Games; a companion volume to "Little Wars"
“ It came out of an accident to a toy engine; a toy engine that seemed done for and that was yet full of life. You know, perhaps, what a toy engine is like. It has the general appearance of a railway engine; funnels, buffers, cab, and so forth. All these are very elegant things, no doubt; but they do not make for lightness, they do not facilitate hill-climbing. Now, sometimes an engine gets its clockwork out of order, and then it is over and done for; but sometimes it is merely the outer semblance that is injured—the funnel bent, the body twisted. ”
