was to be expected, the last period of the morning and the second period of the afternoon show the highest proportion of the accidents, in each case in 1907 and with but one exception in 1897, the first half being approximately 50 per cent of the proportion occurring in the second half of the day. Approximately 55 per cent of the accidents occur in the periods 9 to 12 a. m. and 3 to 6 p. m.; some of the groups of industries show an even more striking concentration of the accidents in the last period of the morning and in the second period of the afternoon; thus the metal-working association for south Germany (association 12) had 37.23 per cent of its accidents in the period 9 to 12 a. m.; the brewing and malting group (association 39) in 1897 had 43.75 per cent of its accidents in the period 9 to 12 a. m. Especial interest attaches to the accident rates on Monday morning and Saturday afternoon; in the period 6 to 9 a. m. on Monday 2.56 per cent of the accidents occur. This is at the rate of 0.85 per cent per hour in this period. In the afternoon many of the associations had a high proportion of the accidents in the period between 3 and 6 o'clock. Thus the Hamburg Building Trades Association (association 43) had 36.51 per cent of the accidents at this period; in fact the building trades are conspicuous by the concentration of accidents in the second period of the afternoon. The columns showing the accidents on Monday morning and Saturday afternoon emphasize the statements already made concerning the higher proportion of accidents occurring in these periods. The best method of comparing the Monday and Saturday accidents with the other days of the week is to deduct the Monday or Saturday percentage from the percentages given in the first eight columns of the table and to assume that the remainder represents the proportion of accidents occurring on the other five days of the week; by this procedure the 2.52 per cent of the accidents occurring on Sunday is credited to the percentage computed for the five days other than Monday or Saturday and makes the contrast less than it actually is. In 1907, during the period 6 to 9 a. m. on Monday, 2.56 per cent of the accidents occurred, as contrasted with 2.26 per cent for the 6 to 9 period for the other five days of the week, or more than one-eighth higher; during the period 9 to 12 a. m. Monday, 4.78 per cent of the accidents occurred, as compared with 4.73 per cent for the other five days of the week, or slightly higher than the average. The higher rate on Monday morning was conspicuous during the early part of the forenoon. In 1897 the per cent of accidents occurring in the period 6 to 9 Monday morning was 2.34, as compared with 2.29 for the other five days; in the period 9 to 12 Monday morning, 4.84 per cent of the accidents occurred while during the other five days it was 4.94. The concentration of the accidents on Monday morning, therefore, was greater in 1907 than in 1897.
