86 STORRS AGRICULTURAL EXPERIMENT STATION. 
regard to the relative cleanliness of individual milkers the ex- 
periments given in Tables Nos. 28 and 29 were carried on. In 
the first series the milk of five of the College students was com- 
pared with an equal quantity of milk from the two regular men 
who were at that time doing the milking in the College stable. 
The method of the experiments was as follows: ‘The students 
milked five cows and poured the entire milk into a forty quart 
can. The regular men also milked five cows and the milk 
was put into another can. A sample was then taken from each 
of these cans and tested for the number of bacteria which it 
contained. In all, the work of five students was compared in 
this way with the work of the regularmen. The students had 
had some work in dairy bacteriology and the production of 
clean milk while the two regular men had not had such train- 
ing. Both students and men, however, followed the same 
course of procedure. ‘The flank and udder were wiped witha 
damp cloth and the milk drawn into the Stadtmueller covered 
pail. ‘The results are, therefore, comparable.

It will be noticed that in every case the number of bacteria found 
in the milk drawn by students was decidedly smaller than was 
found in the milk drawn by the regular men at the same milking. 
In some cases the milk drawn by the regular men contained more
