It is my purpose in this paper to sketch briefly one heretofore ignored facet in American economic history: the influence of British capital, knowledge, and livestock in the growth, development, and eventual decline of the Western range-cattle industry during that colorful, though all too frequently disastrous, period between the American Civil War and the end of the century. Although the locale of this story would seem to confine its interest and importance largely to the West, it was, in fact, an incident of profound national and international importance. It filled the press of the United States with glowing descriptions of great baronial estates teeming with hundreds of thousands of head of cattle; it brought about long articles of analysis, praise, sharp criticism, and denunciation in the British press; it resulted in an internationalbattle of words involving at least three American secretaries of agriculture, presidents of the Board of Trade, ministers of agriculture, and chancellors of the exchequer. There were rude questions in the House of Commons and pointed inquiries in Lords. There were even letters to The Times!
