what did the gulliver do with the 4 days provision in his canae?

He ate them sparingly, and after arriving on the island hid them in a cave.

"I took out my small provisions and after having refreshed myself, I secured the remainder in a cave, whereof there were great numbers; I gathered plenty of eggs upon the rocks, and got a quantity of dry sea-weed, and parched grass, which I designed to kindle the next day, and roast my eggs as well as I could, for I had about me my flint, steel, match, and burning-glass."
