Fia. 11.—Plan for freeing cattle and pastures from ticks by rotation; feed-lot or soiling method. 
after a careful examination made by some one familiar with such 
work that the cattle are free of ticks, they may be turned directly into 
field No. 3A. If they are not free they should be placed in lot No. 3 
until they are free, or, if this can not be determined with certainty, 
until fifteen or twenty days more have elapsed, which will be much 
longer than necessary for all ticks to drop during July and August.
