 make particular examination to determine the facility with which 

 the valves and working parts may be inspected, adjusted or removed 

 for repairs. 



3, The judges may desire the exhibitors to show other engines in 

 regular operation, outside of the exhibition, in order to determine 

 satisfactorily the effect of use on the valves and other moving parts, 

 and the reliability of the engines for continuous practical operation. 

 It is intended that as far as possible all the engines shall be subjected 

 to the same trials, under like conditions. 



The exhibitors and the public will be free to inspect the instru- 

 ments and records, only to such restrictions as wall positively prevent 

 unauthorized interference. 



The experiments will be tried under the constant supervision of 

 the superintendent, and of such of the judges as may be present. 



The data concerning the trials will be collected by competent 

 assistants appointed by the superintendent and approved by the 

 judges. 



4. At the conclusion of the experiments, the superintendent will 

 make a full report of the facts demonstrated thereby, and transmit 

 the same to the judges, together with the logs, records and diagrams 

 upon which said report is founded. 



All suggestions, statements and protests should be in writing and 

 will receive careful attention.
