“We are always happy to receive information here,” he said courteously. “You will understand that I am a very busy man.”

If he thought such a direct hint would arrest the flow of his visitor’s fatal fluency, he was grievously mistaken. Boyle raised an arresting hand, and indulged in some more contortions of arms and hands.

“I recognise the fact, sir, I fully recognise it. A man in your responsible position must find the working hours all too short for what you have to do. You bear upon your shoulders, capable as they are, the weight of Atlas, if I may say so.”

Smeaton had to smile, in spite of himself, at the fanciful imagery. “Not quite so bad as that, Mr Boyle. But a lot has to be got into a limited time, and therefore—”

But his sentence was not allowed to finish. “Say no more, sir, on that head. I can understand that the time of a valuable official is not to be wasted; in short, that you wish me to come to the point.”

Smeaton nodded his head vigorously. Perhaps there was some remnant of common-sense in the creature after all.
