In northern Montana there lies a great, lonely stretch of prairie land, gashed deep where flows the Missouri. Indeed, there are many such-big, impassive, impressive in their very loneliness, in summer given over to the winds and the meadow larks and to the shadows fleeing always over the hilltops. Wild range cattle feed there and grow sleek and fat for the fall shipping of beef. At night the coyotes yap quaveringly and prowl abroad after the long-eared jack rabbits, which bounce away at their hunger-driven approach.
