Mishnah 32a says that if one found an animal on public property, he is obligated to retrieve it.
Mishnah 30b says that if one found a donkey grazing by the road, this is not a lost object and he need not return it.
Q: Assuming the side of the road is public property, these Mishnahs conflict. How do we reconcile?

It is all depends on the circumstances. The Mishnah on 30b is discussing an animal that does not look like it is lost; rather it seems that it was brought there to graze. The animal in the Mishnah on 32b, on the other hand, was found roaming out of town.
