The Scarecrow of Oz

Cap'n Bill, an old sea captain with a wooden leg, and his young friend, a little girl named Trot, are going for a pleasant boat ride on the bay when their boat is engulfed by a giant whirlpool. They spend time on an island with an unfriendly hermit, and discover magic berries which when eaten cause one to shrink or grow, somewhat like the magic foods in Alice in Wonderland. There's a brief stop at another island where the rain is lemonade and the snow is popcorn, complete with butter and salt. Eventually they find themselves in Jinxland, a heretofore undescribed province in the Kingdom of Oz.
