to its rightful owner. In general these laws pre- 
seribe a public advertising of the animal taken, 
and if the owner is known a notice must be sent to 
him of the fact of finding. Since such an animal 
must be fed and cared for, the owner is under obli- 
gation to pay for the keep and other necessary ex- 
penses before regaining full possession. If no one 
is able to prove ownership, the animal may become 
the property of the finder if he so wishes. Should 
the owner refuse to regain possession his refusal

If the finder shall have been a party to the escape 
of the animal, as by leaving a gate open to a pas- 
ture, or by driving off animals on a range, or by 
enticing a dog from home, he will acquire no rights

animal. Where a dog has followed one not his 
owner away from his home, and has lived with 
that person until an attachment has been formed 
for the dog, if the owner has advertised the loss 
where the finder might reasonably have seen the 
advertisement, and sought diligently for his ani- 
mal, whereas the finder has neglected to advertise 
the taking up of the animal, he will acquire no 
rights in the finding, nor for his care of the animal 
while in his possession.

property sold is of value this is not sufficient, but 
a regular bill of sale is to be preferred. According
