REFERENCE was made in NATURE of November 23 and 30, 1916, to the Order directing that millers shall increase the yield of flour from wheat by about 5 per cent. The result was that the corresponding proportion of “offal” was mixed in with the flour. An Order has now been made to the effect that a further 5 per cent. must be added to the flour. This may be done either by taking another five parts of offal for that purpose, or (and this is a most important new departure), at the miller's option, by adding five parts of flour derived from barley, maize, rice, or oats. In addition, he may add voluntarily another five parts, making ten parts in all over and above the previous increase in flour yield of seventy-one to about seventy-six parts of flour from 100 parts of wheat. The result is a compulsory 10 per cent, or a voluntary 15 per cent, more bread with, the use of the same quantity of wheat.
