The vehicles were run for 5,000 miles on the Indianapolis Speedway, and for the remainder of the distance on ordinary roads through 47 States. The results showed that up to 37,500 miles could be obtained from the new tyres, which, after retreading, -could give an additional 23,000 miles, making a total of over 60,000.

APEEP into bus development in America is afforded by the Mack 41-passenger city single-decker, which is going into production for delivery this year. Full details are not available, but it appears that the new model will have a more powerful engine, which will driye through a hydraulic torque converter instead of manually controlled gears.

The relative abundance of metals is generally similar in the sun, in the earth and in meteorites, but striking differences occur in the case of non-metals. The spectrum of the sun's corona is shown to be due to atoms of iron, nickel and calcium in a high state of ionization. Interstellar space is now believed to contain an extremely tenuous gas in which atoms of calcium, sodium, iron and titanium have been detected. The possibility of our using any of these is, however, doubtful.
