Arbelis says it is a common thing for a dog to so strain the muscles of a leg that he it never recovers the use of it. If she were an athlete I should say she had "pulled a tendon". 16th day Sunday, May 20 + 17° F. 7 p.m. Good going until we came to C. Elizabeth Pass and then it was quick and yell our hearts out. Came right up over glacier and are encamped to night on north side of cafe. Have taken lower meridian altitude, height of Mt. Bolten, and sights to Greenland coast. + 11° F at midnight.
