The youngest cowboy in the world is at present visiting this city, says a Fort Worth (Texas) letter to the Chicago News. He is Logan Mulhall, a herd-owner in the Cheyenne nation, and he is just a month, or so over six years old. The boy owns over a hundred head of cattle, has his own brand, which is duly registered, and he does fully as much of his own work as any boy of six has done, even in the West. This very juvenile patriarch is a son of Zach Mulhall, well known through the cow country, and his father is firmly convinced that such another prodigy has not yet appeared in the grazing lands. The young gentleman was formally put in possession of a herd some months ago. He has had made for himself a little Winchester rifle and a special revolver, with both of which arms he is said to be very expert.

The boy has his own bunch of horses and hires his own help, of course under the superintendence of his father, and during the present spring he has every day ridden a line of more than three miles about his herd.

This is a development of young America which the herders in these parts do not believe can be equaled in any other part of the country. The boy is worth about $1200 in his own right and his profits will not be less than $500 a year, which is more than falls to the lot of the average six-year-old.
