of his line through Wyoming illustrated by a number of good photographs. I have suggested that it may be entitled Popular Geology from a Car Window or something of the sort that he can make use of in his advertising matter. I do this with an eye to the future both in the matter of freight and transportation which will come in mighty handy for us. I wish we had as good an opportunity with the Northwestern.

In the matter of the work here at camp I have to report that we have taken up all the Diplodocus in sight as well as the Stegosaurus and Brontosaurus. They are packed and boxed and some 25 boxes are already hauled to Medicine Bow. We have made a cut in searching for the remainder of the Diplodocus about 60 by 40 feet all told. The vertebrae played out at the 24th or 25th presacral. We went in some 10 or 15 feet beyond this point but all we found was a fragment of the posterior end of the lower jaws which would seem to indicate that the skull was destroyed before fossilization occurred. We also dug in about 15 feet to the south but there seems to be very little likelihood of recovering the limbs in that direction; the rock changes character in this direction, running into a very hard concretionary structure very unfavorable for bones. Towards the west however the layer holds its character and looks promising. It necessitates a 6 foot cut however and I think it would be best to let it rest until next season. At that time I hope to have a good strong team and a good road plow with which we will be able to do three times the amount of stripping in the same length of time that we can do now with our present appliances.
