AMONG THE SCIENTISTS

Tiny knobs are attached to the backs of the blades of a new knife so that they may be opened more easily. *" r X scientist in Europe has invented a method for sterilizing the ground In which posts are to be set against insect germs and fungus life. ■- Boring holes into the stumps of hardwood trees and fining these holes with equal parts of nitric and sulphuric acid will so soften the wood that it can be removed by ordinary picks. This has been demonstrated in Gymany, and is the common treatment there of hardwood stumpage. One of the latest electrical inventions is an electric blanket which is designed especially for outdoor sleepers. The blanket is said to have a heating area of four by six feet, and can be regulated to an even temperature of from 82 to 112 degrees by a switch placed near the head of the sleeper. In the Carnegie geogra physical laboratory, Carnegie institute, Washington, D. C., rocks and minerals are now being reproduced by artificial means. In order to do this wojfc the laboratory requires a furnace which can heat to 3,000 degrees Fahrenheit and a machine which can exert pressure to the extent of 10,000 pounds a square inch. The telescribe, an Instrument which records both sides of a conversation, is said to be Thomas Edison’s latest invention. The telescribe consists of a dictating machine which has special receiving appliances and a socket in which the ordinary telephone receiver is placed. The message may be confirmed at any time by use of the dictating machine. _
