Kansas City, Mo., March 14.—The famed Missouri mule, long in dismal decline, cocked his comical ears to night and brayed down the come-back trail. The mule is hitched with the horse to a trend of returning importance. A shortage of both has even AAA of ficials in Washington bothered, but reports here tell of farmers breeding every available mare. It took almost the price of a small car today to buy a “fine span of Mis souri miles” on the Kansas City and St. Louis markets. Sales at as high as $400.00 were reported in St. Louis. “The old Missouri mule is due for a comeback all right,” chuckled Prof. E. A. Trowbridge, of the University of Missouri’ Animal Husbandry Depart ment, at Columbia. “The demand is the greatest I have ever seen. Buyers are swarming here from all over the country.”
