These computations hence indicatethat the accident must have been due to some other cause thanthe radial pressure developed under the normal action of the loco-motive.—Prof. Mansfield Merriman.

Never forget that you must begin at the bottom and not atthe top if you desire results. Scattering seeds over an unpre-pared surface is a waste of time You must plow first!
