Context

“so that in that country you'd be toddling after your mammy yet, and that old chap yonder, who looks about fifty, would only be a little shaver of four and a half." "Blazes! that's a good 'un!" shouted the whole forecastle together. "Solemn truth!" said Joe, stoutly. "But what can you expect? When people will stay in this world, they learn nothing and keep as ignorant as bears. But just come along to Jupiter and you'll see. But they have to look out up there, for he's got satellites that are not just the easiest things to pass." All the men laughed, but they more than half believed him.” source
