definite places immediately back of 

 the cows. It is also suggested that 

 attention be given to adjustment of 

 stalls and that the electric fence wire 

 be used on individual cows that give 

 trouble. 



Scraping Alleyway 



Most of the operators kept the gut- 

 ter alleyways clean by sweeping with 

 a stiff narrow brush. This was done 

 twice or more times a day. This task 

 took from 3.4 up to 27.5 man minutes 

 daily, adjusted to a 40-cow basis. On 

 one farm the operator swept the al- 

 leyway clean twice daily, then cov- 

 ered with a light coat of sawdust, us- 

 ing a hand rake to even it up. The 

 stable looked clean and nice. It may 

 not have been more sanitary. On one 

 farm, the operator used a 14-inch 

 steel scraper which he held at an 

 angle and pushed as he walked the 

 full length of the alleyway. About 

 four trips around the barn com-

pleted the task. He did this once a 

 day in 3.4 man minutes with satisfac- 

 tory results. 



The leaders of this project con- 

 structed a four-foot steel scraper 

 which enabled the workers to do this 

 task satisfactorily in one trip around 

 the barn. This required 1.8 man
