Responsa for Bava Metzia 60:2
אלא לזקן ואינו לפי כבודו
Rabbah said: If he [the old man] smote it [the lost animal], he is [henceforth] under an obligation in respect thereof.<span class="x" onmousemove="('comment',' To return it. By smiting it to make it go in a certain direction he commences the work of returning it, and therefore must complete it. ');"><sup>3</sup></span> Abaye was sitting before Rabbah when he saw some [lost] goats standing. whereupon he took a clod and threw it at them. Said he [Rabbah] to him, 'You have thereby become bound in respect of them. Arise and return them.' The scholars propounded: What if it is dignified for one to return [a lost animal] in the field, but not in town? Do we say, a complete return is required, and since it is undignified for him to return it in town, he has no obligation at all; or perhaps, in the field at least he is bound to return it, and since he incurs the obligation in the field, he is likewise obligated in town?<span class="x" onmousemove="('comment',' On the principle of the preceding dictum. ');"><sup>4</sup></span>

A. A dowry gift becomes the property of the donee only if the marriage takes place. Therefore, neither A nor his daughter has ever gained title to B's money, and A must return the principal plus the interest to B. Even if B expressly stipulated that he will forfeit the 15 pounds if the marriage does not take place, such a stipulation is considered an Asmakhta and is not valid. B, however, must pay A for his trouble in managing B's investments.
