Sir - I am grateful for the support which Mr. Spencer gives in his letter towards the more extensive use of the New Sections, and for adding another to the list of those already rolled given by me.
Sir - May I suggest that the explanation why cement of flattened grain particles gives higher tensile (or compressive) strength is not "mechanical interlocking power;" but a greater exposed surface. The "gell" or "quick" state of the cement particles after the addition of water, will manifestly reach the centre of the flattened grain more rapidly than for a particle with less exposed surface but equal volume.
Rolled steel esctions as articles of commerce, must be efficient commercially, and as materials of construction they must be efficient technically.

Before beginning the paper proper, perhaps a word or so will not be out of
place on the pronunciation of the title, whether it is “Acoostics ” or “Acowstics.”
As a matter of fact, both styles seem to be correct, one dictionary giving one form and one another. The “New Oxford” gives both. Also I understand that “Acoostics” is preferred in Scotland. We may, therefore, safely assume that it is a matter of individual choice.
