been added shall be made up of aliquot parts taken from
each of the several lots of milk or cream bought from each
person concerned, and composite samples of all persons
concerned shall cover the same period of time. The rack or
container where the samples are held shall be plainly
labeled showing the date of the first and last day of the
period covered by the said composite samples. After com-

where they are tested for a further period of not less than
ten days in order to make a possible check test. Every
person, firm, or corporation affected by the provisions of
this sub-title shall, within two days after the day on which

its agents such action is for the public welfare.
