BY THE PROPRIETOR TO THE ENGINEER IN CHARGE, RELATING TO CONDITION OF
THE BOILER,
How long since you were inside your boiler?
Were any of the braces slack?
Were any of the pins out of the braces?
Did all the braces ring alike?
Did not some of them sound like a fiddle-string?
Did you notice any scale on flues or crown sheet?
If you did, when do you intend to remove it?
Have you noticed any evidence of bulging in the fire-box plates?
Do you know of any leaky socket bolts?
Are any of the flange joints leaking?
Will your safety-valve blow off itself, or does it stick a little
sometimes?
Are there any globe valves between the safety-valve and the boiler?
They should be taken out at once, if there are.
Are there any defective plates anywhere about your boiler?
Is the boiler so set that you can inspect every part of it when
necessary?
If not, how can you tell in what condition the plates are?
Are not some of the lower courses of tubes or flues in your boiler
choked with soot or ashes?
Do you absolutely know, of your own knowledge, that your boiler is in
safe and economical working order, or do you merely suppose it is?
