Show TEST OF HOUSE POWER . TO BEMADE Exact Strength of Horses - and Mules to Be Determined Deter-mined at Iowa Fair DES MOINES, la., Aug. tT (By A. P. The first eomprehenslrs tests sver msde to determine the pulling power of draft horses and mulss begsn this morning at ths Iowa stats fair grounds. Ths tests will continue for four daya and the fair board. Iowa State college, the committee on animal motive sower of the Americas Society of Agricultural Engineers, and the Horse Association of Arnsrlca will cooperate. In tabulating the results, re-sults, which, according to Wayne Dtnemore, secretary of the Horoe Association of America, may revolutionize revo-lutionize the methods now ussd tn selecting draft horses. Tha competing animate are divided Into three classes of teams: Fsnn teams weighing less thsn ftOSO pounds: farm teems weighing mors than ioo pounds, and teama not ueed In agricultural work, weighing toot pounds or mors. Will iiisi -rill TT -"-' s '- -specially constructed dynamometer to register Its pulling power sc- The pulling power of a horsa Is not known, and It will ba determined deter-mined accurately for tho flret time by tha I eel a which began today, private tests conducted In England. En-gland. In California, and at the experiment etatlon of Iowa State college at Ames have ahown that soesa horses esa generate sight-horsepower sight-horsepower whsn loaded with weight upon their withers. Without With-out eurh weight, the maximum pulling power on record 1 ! horsepower. RCtUCT WATCH tD. The results of ths test will bo wstrhod throughout tho United Statee and In other count lies for their significance Is broad. They will ahow, for on thing, tho comparative com-parative pulling power of horses and mules, snd they will help to determine which breed or breeds of draft horess excel. In pulling power. The tests will help show, tea, ths relation of horsee form and structure to pulling ability. It la hoped that the teste will lead to slmllsr experimentation to learn ths pulling power of oxen, elephants ele-phants snd besets of burden used I t w mi n I r 1- tn da asrlcul- tursl work and to pull loads, so thst ths horse msy be compared with other pulling anlmale. Comparison Com-parison will be made eventually between the power and efficiency of tha horsa and that of the motor truck. Teete ara being - made to record pulling power on different typea of roe da. to determine te what extent the surface of ftie road effects pulling power. It haa already al-ready been found that teama can pull three tlmea aa much load on a concrete road ae en a dirt road, even when th latter is la good condition. RItCNVt POWER SOUGHT.
