saws, checking material, etc. Make new tool boxes and 

 similarly required staple necessities. 



Keep the work cleaned up. Use up scrap centering, 

 in the boiler. A rainy day can be used to advantage 

 in cleaning, oiling and sorting the bolts used in the 

 centering, or cutting new wire or straps when these are 

 used. Anticipate the needs of better wcathor and be 

 prepared. 



The superintendent should instruct all his good men, 

 men whom he may want to call upon in an emergency 

 or otherwise, to keep him advised at all times of their 

 correct address. Get their phone numbers if possible. 



Surface Finish. There are several methods to 

 choose from in general use which are about as fol- 

 lows: 



Remove the centering while the concrete is green 

 and wa?h off the cement surface, using wire brushes. 

 Beautiful effects can be secured by using beach peb- 

 bles, differently colored granites, etc. 



If the concrete is set. too hard for the above, use a 

 dilute solution of hydrochloric or sulphuric acid to cut 

 away the skin coat of sand and neat cement. Wet the 

 concrete thoroughly before applying acid. 



Rub down with pieces of stone, and brush with ce- 

 ment and water or a thin cement mortar. 



Surfaces can be hand or pneumatic hammered with 

 good results. Any kind of tooled surface can be se- 

 cured with suitable aggregate. Sand blasting has also 

 been used with success. 



A "splatter" finish has been used extensively in Eu- 

 rope, consisting essentially of a "dash" coat of "sloppy" 

 mortar. 



Whitewashing, plastering, cold water paints, are used 

 considerably. On fairly large work, compressed air 

 spraying machines are an economy. 



The most artistic finish is undoubtedly a tooled or 

 acid finish. In this, the superficial coat of neat cement 

 and sand is removed and we see concrete in its un-
