Besides making Drawings, Candidates will be ray -niwotr 



some of a Numlter of Questions on Machine Construction, and illn 

 those answers by sketches. Unless specially instructed to tin 

 trary, the sketches should be drawn five-hand. The capabilr 

 making freehand sketches of parts of machines from nit i; 

 the greatest value to an engineer, and \\hni the sketches are 

 drawn to a tolerable pro|ortion they will be estimated by tin- 

 examiners at at least as high a value as those drawn 

 accurately by means of iiistninu-nts with a much larger expnuli tun- 

 <>f time.
