 importance in the gluing of articles which cannot be heated, 

 as the reed-boards, of cabinet organs, large panels in the bodies 

 of carriages, and in the interior finish of buildings and railway 

 cars, and in all other places where cattle-glue would be likely 

 to chill before the work could be got into position." (Circular
