The Moon Milk Gatherers

Now, you will ask me what in he world we went up on the Moon for; I'll explain to you. We went to collect the milk, with a big spoon and a bucket. Moon-milk was very thick, like a kind of cream cheese. It formed in the crevices between one scale and the next, through the fermentation of various bodies and substances of terrestrial origin which had flown up from the prairies and forests and lakes, as the Moon sailed over them. It was composed chiefly of vegetal juices, tadpoles, bitumen, lentils, honey, starch crystals, sturgeon eggs, moulds, pollens, gelatinous matter, worms, resins, pepper, mineral salts, combustion residue. You had only to dip the spoon under the scales that covered the Moon's scabby terrain, and you brought it out filled with that precious muck. Not in the pure state, obviously; there was a lot of refuse. In the fermentation (which took place as the Moon passed over the expanses of hot air above the deserts) not all the bodies melted; some remained stuck in it: fingernails and cartilage, bolts, sea horses, nuts and peduncles, shards of crockery, fish hooks, at times even a comb. So this paste, after it was collected, had to be refined, filtered. But that wasn't the difficulty: the hard part was transporting it down to Earth. This is how we did it: we hurled each spoonful into the air with both hands, using the spoon as a catapult. The cheese flew, and if we had thrown it hard enough, it stuck to the ceiling, I mean the surface of the sea. Once there, it floated, and it was easy enough to pull it into the boat.
