trial activity new and often inexperienced employees are taken on, and all employees are urged to turn out a maximum product in order to make the fullest possible use of the machinery, and naturally a higher accident rate results. It may also be noted that in times of depression, sending workmen from one establishment or occupation to another is likely to result in an increase in the number of accidents.

TIME WHEN THE ACCIDENT OCCURRED.

MONTH OF THE YEAR.

The month of the year in which the accident occurred is shown in Table 4.

The grand total for all insured establishments in 1907 indicates that the accidents are distributed with a fair degree of uniformity throughout the year; the highest proportion in any one month was that for October, when it was 9.39 per cent of all the accidents occurring in the year, while the month of August, with 8.87 per cent, came second. The month of February having but 28 days naturally had the smallest proportion, with 7.22 per cent of the total number of accidents; in some of the industry groups the distribution of the accidents reflects the seasonal character of the industries; thus in the industry of inland navigation, the association for inland navigation of West Germany (association 60) fluctuates between 5.07 per cent in January and 11.96 per cent in September; in the building trades the Hamburg Building Trades Association (association 43) fluctuates between 4.95 per cent in January and 11.08 per cent in May. Some of the industries in which such fluctuations would not ordinarily be expected show also a wide difference in the proportion of accidents occurring in the different months during the year; thus the fine mechanical products association (association 3) had only 6.62 per cent of its accidents in the month of May, while 9.79 per cent occurred in the month of January.
