He named them after the Duke of Cumberland.

Walker was a genuine explorer and surveyor, a man of mark as a pioneer.

The journal of his trip across the Cumberland to the headwaters of the Kentucky in 1750 has been preserved, and has just been published by William Cabell Rives (Boston: Little, Brown & Co.).

It is very interesting, and Mr.Rives has done a real service in publishing it.

Walker and five companions were absent six months.
