J. M. PARKER. 
improvement of our dairy farms should have escaped notice as 
it has. It is not a new subject. For many years past authori¬ 
ties have discovered that the principle predisposing causes of 
tuberculosis are poor sanitary and hygienic conditions, and yet, 
notwithstanding the universal prominence given to sanitary 
conditions as predisposing causes, they are almost entirely 
ignored among the prophylactic measures suggested by many of 
these same authorities. 
As showing that sanitary conditions are not observed as they 
should be on dairy farms, I have attempted to tabulate the 
conditions as found on twelve farms in this vicinity. These are 
not picked out, but are taken at random from farms visited from 
day to day. The table shows roughly the amount of cubic 
space per cow; the ventilation, light, water supply; whether 
there is a cellar, with its condition, and how the manure is 
disposed of.

You will notice as a rule the cattle are far too crowded. In 
the city of Boston each animal must have 1,000 c. f. of space, 
and probably, with good ventilation, that may be sufficient; 
at any rate, it is an immense improvement on many farms in 
other parts of the state; but even 1000 c. f. is altogether in¬ 
adequate if there is no ventilation. What must be the conditions 
of the barns then, when as in No. 5, there is only 143^ c. f. for 
each animal, with no ventilation. In only three farms out of 
the twelve, you will notice, is there any attempt at ventilation,
