The United States is also credited with having 25 horses per 100 population, outranking other countries in this respect^ To date census figures for 1920 give the horse and mule popula tion of the United States to be 27,676,939.= That the horse industry of the United Stat^ particularly of the draft type, is to remain the source of reliable, efficient, and economic power for the major body of agricultural workers and transportation men, is evident A very plausible undertaking, Uie "National Survey of the Economic Status of the Horse," sponsored by the saddlery interests,® has been made, the results of which bear fruit in accord to the foregoing assertion. This survey, among other things, discloses the following:' "tl) All data gathered and studied indicates that the tractor in its present state of development is a means of supplementary or auzilliary power rather than a substitute for the horse. "(2) That the tractor to date has made no appreciable dent in the number of horses on our farms. In at least 50% of the cases just as many horses are kept as after its purchase. "(3) Actually, horse displacement which can be credited to the tractor is very, very small, and in no case are the horses displaced equal in value to the tractor which displaced liiem. "(4) That the horses remaining after the tractor has been purchased perform on the average from 75% to 90% of all the work." The survey also points out that the increase in the number of horses and mules has always about kept pace with the increase in population and agricultural expansion, excepting only from 1900 to 1910. Relative to the effect of the introduction of motor trucks on the farms, the survey reveals the fact that in January, 1919, there were 184 times as many horses and mules as there were of motor trucks, so that the influence is very little. It is mentioned that only one farm in nearly fifty has a truck. As to the part played by draft horses in city haulage it is worthy of note to consider the following findings:' "For all hauls within a radius of 2 or 3 miles where a number of stops are made firom terminal to down town business houses—^haiiling in many cases is superior and in all cases cheaper. Long delays at terminals seem to be inevitable and when this delay amounts to 2 or 3 hours it is quite obvious that the horse is mudti cheaper due to the small investment idle. Added to this, it is possible to use horses in many alleys and such places that would <be almost inaccessible for a motor truck. "A number of cartage concerns also handle contracting work, such as excavating. In this field it was also clearly demonstrated that the horse has his place. First, in getting into excavation the horse could often get into places where a motor truck could not go. It also was un necessary to build heavily planked roadways for the horse as are necessary to give the truck traction. This also holds true on the dump. "In ice companies, bakeries, creameries, etc., having short hauls and regular stops or routes the horse has a distinct place. The truck could 8 PURE BRED DRAFT HORSES not make any better time over a given route than a horse could. The horse could carry just as big a load and the cost was much less." Back of the horse industry the country must look into the breeding operations as the basis for the output of proper classes and number of horses to keep pace with the requirement in the United States.
