Mishnah 7 in chapter 9 of Maseches Shabbos deals with the measures that create liability for carrying on Shabbos: what quantity must a person carry out in order to be liable, and what the law is when many different items are carried out together in a single container.
The Peddler's Basket:
"HaMotzi kupas harochlin, af al pi sheyesh bah minin harbeh - eino chayav ela chatas achas" - one who carries out a peddler's basket, even though it contains many different kinds of items, is liable to only one chatas. Peddlers were dealers in spices and cosmetics, and their baskets held many varieties and many different types of merchandise. Even so, one who carries out the basket on Shabbos is liable to bring only a single chatas, because the basket itself joins everything inside it into one act of carrying.
Garden Seeds:
One who carries out seeds that are normally planted in a garden is liable even for less than the volume of a dried fig. The measure of a dried fig is the fixed measure for carrying out food, but these seeds are not intended for eating but for planting, and therefore their importance is not measured by the standard for food but by a smaller amount.
And these are their measures:
"Rabbi Yehudah ben Beseira omer: chamishah" - Rabbi Yehudah ben Beseira says: five. Carrying out five seeds is enough for it to be considered the carrying of something significant.
"Zera kishuin - shnayim" - cucumber seeds: two. Two seeds alone are enough.
"Zera deluin - shnayim" - gourd seeds: two. This includes the various kinds of gourds.
"Zera pol haMitzri - shnayim" - seeds of the Egyptian bean: two.
The Measures for Locusts:
"Chagav chai tahor - kol shehu" - a live kosher locust: any amount at all. A live kosher locust, whatever its size, is considered significant enough to create liability for carrying it out on Shabbos, because people would give it to a child to play with.
"Mes - kigrogeres" - if it is dead: the volume of a dried fig. Once the locust has died, its status is that of food, and therefore its measure is the volume of a dried fig. Locusts were eaten after they died and not while they were alive, and a locust does not require shechitah, so once it dies it is kosher food, and its measure is the measure for food.
"Tzipores keramim, bein chayah bein mesah - kol shehu, shematznin osah lirefuah" - a vineyard bird (a species of locust), whether alive or dead: any amount at all, since people store it away for medicinal use. This is a particular species of locust whose measure is any amount at all, whether alive or dead, because people would put it away and keep it for medical purposes. That was its purpose.
The Dispute Between Rabbi Yehudah and the Tanna Kamma Regarding a Non-Kosher Locust:
"Rabbi Yehudah omer: af hamotzi chagav chai tamei - kol shehu, shematznin oso lekatan lesachek bo" - Rabbi Yehudah says: even one who carries out a live non-kosher locust is liable for any amount at all, since people store it away for a child to play with. Even a locust that is not kosher, so long as it is alive, has a measure of any amount at all, since people would put it away so that a child could play with it.
The Tanna Kamma, by contrast, permits giving a child only a live kosher locust to play with, out of concern that the non-kosher locust might die and the child would come to eat it, and it is not kosher. Rabbi Yehudah disagrees and is not concerned about this, and in his view one may give a child even a non-kosher locust to play with while it is alive, and for that reason the measure of a live non-kosher locust is likewise any amount at all.
In summary: in this Mishnah we learned that a basket joins together all the varieties inside it so that there is liability for only one chatas; that garden seeds, which are not meant for eating, have a measure smaller than a dried fig and consist of just a few seeds; and that the measures for locusts are determined by their purpose - a live locust used as a plaything and a vineyard bird used for medicine have a measure of any amount at all, while a dead locust, whose status is that of food, has a measure of a dried fig. On this basis Rabbi Yehudah and the Tanna Kamma disagreed as to whether a live non-kosher locust may also be given to a child to play with.
