to coloring the cheese in order to cover up the spots. In some 
cases the factory would have no trouble until the autumn months, 
when it would suddenly develop very rapidly, quite often be- 
coming so marked that it was impossible to cover it with annatto. 
“The spots were rarely discovered in the early spring months, yet 
there were some factories where they showed to a greater or less 
degree throughout the whole season. 
About ten years ago this trouble developed in the factory at 
Hailesboro. This factory had good drainage and was well built 
and well managed. The trouble continued for a number of sca- 
sons and the financial loss was some hundreds of dollars. The 
method of manufacture was changed and a very dry, high-culored 
cheese made, but the trouble was unchecked and the spots showed 
through the cheese-color. As a last resort the making of cheese 
was abandoned and the cream was made into butter, although the 
financial returns were then less than those obtained from good 
cheese. The making of butter at this factory is still continued. 
We have not received a report of a serious outbreak of the 
trouble in St. Lawrence County during the last few years. 
The Miller factory at Constableville had an outbreak of the 
spots about 1888. Here it was so severe that coloring the cheese 
failed to cover the discolorations. The factory lost heavily both 
in patronage and in the price of its product. The trouble con- 
tinued until the total destruction of the factory by fire some years 
later. A modern factory was built near the site of the old one 
and there has been no return of the spots reported. 
The old Harrisburg factory in Lewis County had an outbreak 
of the trouble in August, 1895. Reappearing in April, 1896, it 
lasted throughout the season and was so bad that the blotches 
showed through the cheese color. There was less of it in 1897 
and since that time it has not appeared. An old upright press 
which was discarded in the overhauling which the old Harris- 
burg factory received while fighting the rusty spots was taken 
to the adjoining Silver Springs factory. Trouble soon developed 
in the latter and continued until it resulted in the closing of the 
factory. After standing idle one season the factory was thor- 
oughly overhauled and partially rebuilt. Since that time no 
trouble has been reported.
