`` There 's going to be a meeting of the Board of Health to consider the subject soon , and I 'll give you fellows the tip the minute I hear anything definite about what they decide to do . '' `` In the meantime , suppose you fellows drop around this evening for a little while , '' suggested Bob . `` I want to try out some long distance receiving and listen in on Chicago .

He was surprised to find that the callers were Mr. Looker and his son Buck .
