4 TEXAS AGRICULTURAL EXPERIMENT STATION. 



lambs were sired by Shropshire rams on Delaine range-bred ewes, and 

 showed a remarkable degree of type and uniformity, all being block 

 compact, and carrying their bodies close to the ground. These lambs 

 were dropped in April, and during the spring and summer they grazed 

 with their mothers on the range, no concentrates in any form being 

 supplied prior to the inception of the test. When the selection was to 

 be made 800 lambs were driven through the chute and 501 of the choice 

 individuals cut from the flock. 



The lambs were equally divided insofar as size, quality, and type 

 were concerned. Two hundred and fifty lambs averaging 46.55 pounds 

 were placed in Lot 1, and two hundred and fifty-one averaging 46.92 

 pounds were placed in Lot 2. 



Mr. Boog-Scott purchased the Gay interest in the flock at the rate 

 of $5.75 per hundred pounds live weight, this figure approximating the 

 Fort Worth quotation on the same class of lambs at that time.

FEED LOTS AND WATER SUPPLY. 



During this test the lambs occupied two adjoining lots that sloped 

 in a direction southernry to the river transversing them. Owing to the 

 southern slope, the lambs received considerable protection from the 

 cold north winds. Another desirable feature of these lots was that dur- 

 ing the rainy weather the water readily drained and the lambs were not 

 forced to stand in deep mud. There were eighteen rainy days during 

 the test and. the total preciptation as reported by the weather observer 

 at Coleman amounted to 8.49 inches. As no provision had been made 

 to shelter the lambs from the protracted rains, they were forced to re- 

 main in the open during all conditions of weather. None of the lambs
