it is hard to say. According to Bells dip of 40 fut to the mile it could make 160 fut but somehow it does not seem to me more than 50 to 70 fut. All in all the afternoon had little interest because we started out to see the center of the Anchawian with the Shurmin. To see this we should have gone at least three miles further which would have made the afternoon overall at least 14 miles.
