Extract

I do not wish by this title to imply that there is not to be another phase to this experiment, but owing to climatic differences between Ohio and South Africa, whereby our winter months are their summer months, the export side of the problem came first. Next autumn, in South Africa, but spring rvith us, the tide of transportation will set in in the other direction.
