Nath, with his natural curiosity of machinery, was drawn to the sound of working steam drifting over the fells and had to investigate. To his surprise a large derrick was being erected and workmen were preparing to clear debris from the site of the explosion. Nath watched in fascination as the crane and workmen worked.

Excellent picture.
Victor did do a good job on the picture, I must agree.
