looked in at the open door. They seemed interested, 

 and the honours of the little shed were done to them. 

 On resuming duty, while the visitors still lingered, 

 the electrician said to his assistant, ' I wish we had a 

 reversing- switch.' The visitors disappeared, only to 

 return from a thicket hard by with a bundle of twigs 

 neatly cut, which were shyly tendered, and a hope 

 was expressed that one of the switches might do.
