You will observe, however, that the Clerk of Works has
raised the question of the effect of these materials on the
wood floors, and I should be obliged for any observations

materials being used), so that the atmosphere may remain
approximately as free from dust particles as it does now with
dust allaying preparations in use.
Please consider the whole question of dust allaying
preparations versus school cleaning, as on trial, and let me
have any opinions you may have to offer as to the relative
advantages of the two methods, or any other points arising
out of this letter as the result of your own experience and
observations.

September, 1914, as follows:—
