THE SUN'S ENERGY.

7000 H.P. PER ACRB_PEB DAY.

[PBESfc ASSOCIATION.] / LONDON, March 6. Sir J. J. Thomson, Professor of Physics at the Royal Institution, states that the sun transmits power on a clear day equivalent to 7000 h.p. to the acre. If this power were harnessed all the power required for the world's work would be obtained at the cost of lowering the temperature a degree or two. iThe suggestion that radio-activity is the cause of the sun's energy Sir J.J. Thomson regards as useless, because the life of radium is insignificantly short. The only tenable hypothesis is Helmholtz's which traces the energy of the sun to the shrinking within itself to the extent of about 200 feet per year.
