with small sketches of Indians and their ways. Then came a picture of a cheerful and corpulent ecclesiastic in a shovel hat, sitting opposite a very thin European, and the inscription: “Lunch with Fra Cristofero at Rosario.” Studies of women and babies accounted for several more pages, and then there was an unbroken series of animal drawings with such explanations as “Manatee upon Sandbank,” “Turtles and Their Eggs,” “Black Ajouti under a Miriti Palm”—the matter disclosing some sort of pig-like animal; and finally came a double page of studies of long-snouted and very unpleasant saurians. I could make nothing of it, and said so to the Professor.
“Surely these are only crocodiles?”
“Alligators! Alligators! There is hardly such a thing as a true crocodile in South America. The distinction between them—”

I was still unable to sympathize. It was a full-page sketch of a landscape roughly tinted in color—the kind of painting which an open-air artist takes as a guide to a future more elaborate effort. There was a pale-green foreground of feathery vegetation, which sloped upwards and ended in a line of cliffs dark red in color, and curiously ribbed like some basaltic formations which I have seen. They extended in an unbroken wall right across the background. At one point was an isolated pyramidal rock, crowned by a great tree, which appeared to be separated by a cleft from the main crag. Behind it all, a blue tropical sky. A thin green line of vegetation fringed the summit of the ruddy cliff.
