FALLING INTO FORTUNE

CHANCE DISCOVERIES THAT HAVE PROVED VALUABLE In the modern ice-cream barrow the cream is kept frozen by use of “dry ice—that is solidified carbonic-acid gas. A boy in charge of one of these barrows found that, when he took a piece of this dry ice and put it against the bell of his bicycle, the bell would give a rattling ring. From this it was discovered that frozen carbon dioxide produces notes whenever it touches metal and, as a result, a new method has been found for helping musical instrument makers to attain perfect tuning. A Durban metal worker was asked by a friend to nickel a candlestick. Though this was against the rules of the firm he consented. The regular process was to plunge the article a number of times into an electric bath, a slow and costly process, but as an experiment this man-, tried a special metal finish. The result was so good and so rapid that he took the idea to his employers and the resultant saving in the factory is £3OOO a year. Tar paving was discovered by a boy who was sent for two gallons of tar to dress a roof and on his way back upset the tar in the road. Later it was found that the stones were firmly bound together, and so came about tar macadam.
