Sometimes Providence interferes and saves the beginner from all trouble with his stops. It did so with me. I had a dog which took a great interest in my first camera from the very beginning. There is, perhaps, something about morocco leather which reminds a dog of the Elysian fields. It was a lens-cap, morocco bound outside, velvet inside, which Charlie devoured first. A cork out of a pyro bottle fortunately fitted the lens-hood exactly. Then, after eating the cap, while my head was under the focusing cloth, Charlie devoured the leather case, with all the stops in it. This was an insurmountable difficulty. I know I wrote to the maker of the lens to ask what a new set would cost, but as the amount was more than I possessed, I determined to do without. That is why I was saved from under-exposure, with I should surely have been led into with a multitude of stops.
