אֵלּוּ מְצִיאוֹת שֶׁלּוֹ, וְאֵלּוּ חַיָּב לְהַכְרִיז. אֵלּוּ מְצִיאוֹת שֶׁלּוֹ, מָצָא פֵרוֹת מְפֻזָּרִין, מָעוֹת מְפֻזָּרוֹת, כְּרִיכוֹת בִּרְשׁוּת הָרַבִּים, וְעִגּוּלֵי דְבֵלָה, כִּכָּרוֹת שֶׁל נַחְתּוֹם, מַחֲרוֹזוֹת שֶׁל דָּגִים, וַחֲתִיכוֹת שֶׁל בָּשָׂר, וְגִזֵּי צֶמֶר הַבָּאוֹת מִמְּדִינָתָן, וַאֲנִיצֵי פִשְׁתָּן, וּלְשׁוֹנוֹת שֶׁל אַרְגָּמָן, הֲרֵי אֵלּוּ שֶׁלּוֹ, דִּבְרֵי רַבִּי מֵאִיר. רַבִּי יְהוּדָה אוֹמֵר, כָּל שֶׁיֶּשׁ בּוֹ שִׁנּוּי, חַיָּב לְהַכְרִיז. כֵּיצַד. מָצָא עִגּוּל וּבְתוֹכוֹ חֶרֶס, כִּכָּר וּבְתוֹכוֹ מָעוֹת. רַבִּי שִׁמְעוֹן בֶּן אֶלְעָזָר אוֹמֵר, כָּל כְּלֵי אֶנְפּוֹרְיָא אֵינוֹ חַיָּב לְהַכְרִיז:
Which metzioth are his (the finder's) and which must he call out? These metzioth are his: If he found scattered fruits [(It may be assumed that the owner "despaired" of them, and they are hefker)], scattered money [(Since it has no distinct siman, the owner "despairs" of it, and it is hefker, and so with all of these)], small sheaves in the public domain, [where all tread upon them, so that even if it had a siman it is obscured], rounds of figs, loaves of a baker, [which have no siman, all of them being alike; but home-made loaves do have a siman.], strings of fish, pieces of meat, wool shearings that come from their provinces, [to exclude those that come from the tradesman's house, as taught below], bundles of flax, tongues of wool [dyed] purple — these are his. These are the words of R. Meir. R. Yehudah says: Whatever has a shinui (a distinguishing difference) must be called out. How so? If he found a round [of figs] and in it a shard; a loaf, and in it money. R. Shimon b. Elazar says: All anpuria vessels need not be called out. [("anpuria":) new vessels, which are not familiar to the eye, so that the owner cannot identify them as his own by visual recognition. (For sometimes a lost object is returned on the basis of such recognition, as in the instance of a Torah scholar, who does not prevaricate.) And these vessels, about which it is known that the owner cannot identify them by visual recognition, need not be returned. The halachah is in accordance with R. Shimon b. Elazar. When is this so? When they are found individually. But if they are found in twos, they must be called out, for the number is a siman. And if one finds a metziah in a broad thoroughfare in a city, where the majority are gentiles, even something with a siman, he need not call it out. And in a city with a majority of Jews, he must call it out.]
