Dr. H. A. Wolff, who is to lecture on the "Transvaal and the Present Crisis," next Monday evening in Sanders Theatre, is a graduate of Amherst, class of 1874. He has spent eighteen years in South Africa, mostly in the Transvaal. He was a member of the famous Reform Committee of the Johannesburg Outlanders. He can therefore speak from personal knowledge of the stirring events leading up to the present war.
