BRICK VERSUS CEMENT WORK.

but do not think I have written this to praise Portland cement 

 buildings in preference to other materials, but I have written 

 this paper more to show that all materials should be taken 

 fully into consideration and to be used according to circum- 

 stances requiring them ; for I consider all materials equal if 

 used in a proper manner and in their proper places. And 

 where good stone, white or red bricks are to be obtained, I 

 say use them, but if only of an inferior quality, cement would 

 be better ; if in cement, the work underneath should be carried 

 out in a workmanlike manner, leaving the faces rough for a 

 good key to take cement.
