So dark bottle equals " not food."

所以，黑瓶子等于“不是食物”。

Another chant from Hagar produced another apparition, not a lovely one, for with a bang an ugly black imp appeared and, having croaked a reply, tossed a dark bottle at Hugo and disappeared with a mocking laugh.

哈伽又唱了一支歌，召来另一个讨厌的鬼魂。因为随着砰然一响，来的是一个丑恶的小黑鬼，他嘶哑地回答了一声，把一只黑瓶子抛向雨果后，发出讥嘲的笑声就不见了。
