Poor young men _7_in cities with lots of smoke and dirt were_8_ to buy white celluloid collars(領(lǐng)子).The collars were hard and uncomfortable. But they did not have to be sent to wash. The poor young men _9_ rub them clean every evening with soap and water! Poor mothers,
_10_ had not been able to afford playthings _11_their children, were now able to buy them playthings _12_ of celluloid. But celluloid had one very serious fault. It caught fire very easily.
