EXPERIMENT STATION. 



[Jan. 



The grand totals may be further subdivided into the several

The manufacturers repeatedly protested against the refusal 

 of their glassware, and asserted that similar shipments were 

 passed in other States. Such might easily have been the case, 

 where the error was small, due to differences in method of test- 

 ing or in allowable limit of error, possibly both. In some 

 instances the condemned pieces were forwarded to another sta- 

 tion and retested, but even this apparently failed to satisfy the 

 manufacturers. It became evident that further investigation 

 was necessary in order to bring the matter to an unquestion- 

 able basis and to remove all reasonable grounds for complaint.
