laths being made with beveled edges so that when nailed 

 onto the sheeting horizontally, the same way as the sheet-

 it is broken. The patent grooved lath might be used, 

 but they cannot be sprung to a twenty-foot circle. Better

 or metal lath of one form or another, such as is now gen- 

 erally used in outside plastering of houses, nailed on strips 

 of Ix2's which are placed 15 inches apart, and nailed onto

 and possibly cause the plaster to crack, as would be likely 

 to occur in case of wooden laths. For outside sheeting
