Any person who shall milk the cow of another, knowingly, without his consent, or who shall pen or confine by any means any milk-cow, or the calf of any such cow, not his own, with intent to procure milk from such cow, without the consent of the owner, shall, on conviction, be fined not more than one hundred dollars, or be imprisoned in the county jail not more than three months, or both. Proof that any one penned or confined any cow or her calf not his own, shall be deemed prima facie evidence of an intent to procure milk in violation of this section.
