And _Diplodocus_ was the result.

Hind limb of _Diplodocus_.] My own connection with the discoveries of these old dinosaurs continued only through the following summer, in Wyoming, when we added the first mammals from the hills immediately back of the station, and the types of some of the smaller dinosaurs, and when we explored the vicinity for other deposits, on Rock Creek and in the Freeze Out Mountains.
How many tons of these fossils have since been dug up from these deposits in the Rocky Mountains is beyond computation.

My prophecy of hundreds of tons has been fulfilled; and they are preserved in many museums of the world.

One of the charms of the fossil-hunter's life is the variety, the element of certainty combined with the gambling element of chance.
