SOVIET writers have good cause for satisfaction in the achievements of their country in the field of geology since the Revolution of 1917. This justifiable self-satisfaction has a less justifiable corollary in the constant emphasis on the backwardness of pre-Revolutionary Russia. The pace of scientific progress has increased everywhere in the last few decades, both from its own momentum and because of the vast increase in the number of workers in the field; but this should not detract from our appreciation of the worth of earlier patrons and scholars working in less favourable circumstances.
