THE system of giving checks for hats and coats which has just been introduced at the Library is a much-needed improvement. It is a matter of regret that such a system should be needed, but if persons who visit the Library will insist on stealing hats and coats, it is better that something should be done to prevent them. Last Saturday afternoon some individual coolly walked off with two fifty-dollar overcoats; how he did it is a mystery, as he must have passed in full view of the attendant at the desk and all the persons in that part of the Library. He had evidently heard that the check system was to be introduced on Monday, and thought that he would make hay while the sun shone. We believe that two other overcoats have also been lost from the Library this year, besides innumerable hats and umbrellas. It would have been somewhat better, perhaps, to have locked the barn door before the horse was stolen, rather than after, but we can comfort ourselves with the assurance that there will be security in the future.
