STRAW IN BRICKS.
[To THE EDITOR OF THE " SPECTATOR."'
Sia,—There seems to be some uncertainty among your corre- spondents as to how straw is used in making bricks. In the Argentine all bricks are made with straw. The broken straw which comes from the thrashing machine, and is otherwise useless, is tramped up in ordinary mud by means of horses until it becomes sufficiently glutinous to be laid out by the wooden mould. When dried in the sun the bricks are stacked
up and burned.—I am, Sir, &c., E. B. T.
