LOSSES. 
The losses of bees by disease, principally foulbroodj during 
the summer, range from practically nothing to almost 10 per 
cent in some States, though the latter figures are exceptional 
and may be due to mistaking starvation for disease. The 
losses to bees in wintering are severe, ranging for the United 
States as a whole from 10 to almost 15 per cent, and rising 
in some States to almost 50 per cent in the winter of 1916-17. 
Details for three years are shown in Table IV. The losses 
for the winter of 1917-18, owing to an early and exceedingly 
severe winter, are reported at 18.7 per cent, more than a half 
greater than the average of the three preceeding winters, and 
the heaviest in a long period of years.
