John Trapp on Psalms 107:35

Verſ. 35. He turneth the wilderneſs, &c.] Some place a again, God (to ſhew his power and providence) of ſteril maketh to become fertil; Pol[illegible: 2 letters]ia for inſtance, and other Northern Countries. Germany and France were of old full of Woods and Lakes, as Ceſar and Tacitus teſtifie, now 'tis otherwiſe. So in America at this day. So divers deſert places of Egypt and Ethiopia, when once they became Chriſtian, became fruitfull.
