We finish our summer reading of C.C. Long’s “Home Geography” in EPISODE THIRTY FIVE.  Lessons 33 through 45 round out this primer for developing our own geographical imaginations.   Long reminds us, “All around are illustrations of lake and river, upland and lowland, slope and valley. These forms must be actually observed by the pupil, mental pictures obtained, in order that he may be enabled to build up in his mind other mental pictures of similar unseen forms.”
