Recently, a " non-con- 
ducting can " has been in- 
vented for shipping this 
kind of milk. It is of 
tin, and nearly of the same 
form as the carrying-cans, 
but double, with a space 
of 2 inches between the 
outer and inner surface, 
which is closely packed 
with ground felt. Fig. 10 
shows the general form of 
this can. In these cans 
the milk goes to market 
in sound condition. 
The Combined Factory. 
I have alluded to the modern plan of combining with the 
manufacture of condensed milk that of cheese and butter ; in 
other words, the fitting up of a factory in which either the one 
or the other or the whole of these products can be made from 
the daily delivery of the milk. Experience has shown that the 
combined factory is the safest, and in most instances should be 
adopted. There are certain seasons of the year when it is 
more difficult to make good condensed milk than at others. 
There are times, too, when the milk received does not prove to 
be in that prime condition necessary for condensing, but which 
might suffice for the manufacture of cheese. Again, the breakage 
of machinery might render it impossible to condense the milk 
for a day, and perhaps for longer periods ; changes in the market 
may also render it advisable to put a smaller quantity of milk 
through the condensing process for a day, a week, or a month, 
than at other times. 
These, and a variety of other circumstances occurring, or 
liable to occur, require at the factory ample means for manu- 
facturing the milk into some other form than that of con- 
densed milk. For it must be observed, that after a number 
of persons have been engaged to deliver milk at the factory, it 
must be received, if in good order; and, unless provision be 
made for its manufacture in some form, heavv losses will ensue. 
When arrangements are perfected for turning the milk into
