In the construction of a lock at the St. Mary’s Falls Canal, the laying of masonry was discontinued about October 20th of each year on account of the frequent recurrence of freezing weather. On the last day of the work in 1877, mortars of Portland cement and of a good quality of American natural cement were used in adjoining portions of the wall. The same proportions of cement and sand, 1 to 1, were used in both classes of mortar. This masonry was laid during a light rain. The following spring the surface of the Portland cement-mortar was sound, showing perfectly the marks of the rain drops. The natural cement-mortar was disintegrated to a depth of 3 or 4 inches.
