SANITARY CONTROL OF TOMATO-CANNING FACTORIES. 27 
condition reported that instead of having a shortage of suitable help 
he had on file a waiting list which enabled him to fill any vacancies 
on his force with selected help, although some factories near by were 
finding it impossible to get sufficient help. 
The factory might well be regarded as a cooperative institution 
and the employees made to feel that its welfare is a part of their 
personal concern. Clean dressing rooms, clean, sanitary toilets, and 
simple provisions for caring for emergency accidents will be ap- 
preciated by nearly all the employees. But in order to attain such 
an esprit de corps the superintendent or manager himself must be 
foremost in planning and systematizing the work of cleaning, which 
must be begun at the opening of the season and tactfully enforced 
throughout the entire season if it is to prove successful. 
LABORATORY CONTROL. 
From the standpoint of law enforcement, laboratory methods of 
examination are necessary, since there is no other way by which the 
officials on whom rests the responsibility for enforcing the law can 
judge correctly whether the product comphes with the law’s require- 
ments. Without the check afforded by laboratory methods the 
product of insanitary factories would come into open competition 
with sound and good products, and in such condition that the con-' 
sumer usually would be unable to detect its true, offensive nature. 
Large manufacturers who have analysts thoroughly well-trained 
in microscopical methods have also found laboratory supervision of 
great value as a means of checking the work of their sorters and 
superintendents. The fact that the character of their work can be 
determined from an examination of the finished product is a strong 
incentive toward inducing employees to exercise a greater degree of 
care in the various details of manufacture. It is well also for the 
analyst to check his work from time to time with that of other reliable 
analysts in order to keep his own operations in agreement with those 
« “ others in the same line. No conscientious analyst would undertake 
_ do careful analytical work for a manufacturer before he had 
j roved himself reliable through experience with the product and 
through checking his findings with those of other analysts, known 
to be reliable. 
The manufacturers also may test the ability of their analysts by 
submitting to them sterilized portions of the same sample at dif- 
ferent times under different identifying marks. It is of the utmost 
importance, however, that the samples be exact duplicates, for if 
they have not been taken from the same batch after thorough mixing 
and then kept under sterile conditions the results are utterly worth-. 
less for purposes of comparison. It is the writer’s belief that some
