    "abstract": "ENGLAND'S being a so-called free trade country, we receive and use a large proportion of imported projectors, some manufactured under metre and some under standard dimensions. The first defect discovered by the exhibitor or his operator is that the spool spindles only accommodate spools made for, or by, the same manufacturer, and if the installation has machines of different makes, the operator has to see that film reels 1, 3 and 5 are on one type of spool, and reels 2, 4 and 6 on the other. He also requires two rewinders accommodate same, or must have the spool spindles altered on one of the machines to match the other, which is the usual course adopted.",
