 This should be done as

 concrete is laid, first wet- 

 ting the surface. 



Concrete may be greatly 

 strengthened, and conse- 

 quently thinner walls may 

 be used, if it be rein- 

 forced with iron or steel. 

 One row of No. 8-gauge 

 black fencing wire placed 

 every 6 inches in height, 

 and vertical wires about 

 one foot apart, are all that 

 is necessary. Walls thus 

 strengthened need not b? 

 thicker than 3 inches. 

 Double this thickness 

 would be necessary with- 

 out the wire reinforce- 

 ment. Boards must be 

 used for forming the 

 walls. Where boards are 

 plentiful, a wall should 

 be built in one day, add- 

 ing board after board as 

 the concrete is filled in to 

 the top of each. The 

 boards can be removed 

 the following day and 

 used for wall on opposite
