And every colony has a name, which is a number, which is painted on a rock. And I go there every year and look for all the colonies that were alive the year before, and figure out which ones have died, and put all the new ones on the map.
我给每个蚁群都标了号， 并把号码标记在石头上。我每年都会过去 寻找前一年生存的蚁群 看看哪些已经死了，并把新的蚁群在分布图上标记出来。
