In a famous case three years ago, involving the rates on 400 commodities from the Middle West to the Pacific Coast, the Commission held that a differential between carloads and less than carloads, which is at once more than 50 cents per hundred and more than 50 percent of the carload rate, is _prima facie_ excessive, and puts the railroad on the defensive to show special reason why so great a difference should be made.[235] The difference between the carload rates and less-than-carload rates, involved in this complaint, was held to be excessive in many cases. On the Yazoo and Mississippi Railroad and the Illinois Central, 1 horse can go 667 miles for $36 and 4 horses pay $99, while 25 horses can take the trip together for $100. This encourages social habits. The first horse is billed at 2,000 lbs. no matter what he really weighs; the second is billed at 1,500 lbs.; and each additional animal counts 1,000 lbs. The rate is double first-class, or $1.80 per hundred, which the Commission says is twice the fair rate.[236] In a recent case it appeared that the Texas and Pacific was charging 42½ cents per hundred lbs. on cattle from Fort Worth to New Orleans, and $15 a car additional on a shipment of less than ten carloads. This addition of $15 a car was held unreasonable.[237] For 17 years the road made a much lower rate—34 to 40 cents per hundred lbs., without any $15 a car additional. In March, 1903, the rate was raised to 42½ cents, and in October of the same year the additional charge of $15 a car was imposed. The distance is 500 miles. The distance from Fort Worth to Kansas City is about the same, while to St. Louis it is 700 miles. The rate on cattle from Fort Worth to Kansas City is 36½ cents, and to St. Louis 42½ cents, without any $15 addition. The Commission held the $15 charge to be an unjust discrimination between the large and small shippers, and against New Orleans in favor of St. Louis.
