One-third barrel of plaster (stucco) will hard-finish 100 square yards plastering.

One barrel of best lime will lay 1000 bricks.

Two barrels of lime will lay one cord rubble-stone.

One-half barrel of lime will lay one perch rubble-stone (1/4 cord to perch).

To every barrel of lime estimate about 5/8 cubic yard of good sand for plastering and brick work.

A barrel of portland cement contains approximately 31/2 cubic feet, and weighs 380 pounds ; a bag contains about 7/8 cubic feet, and weighs 95 pounds. A barrel of natural cement contains approximately 31/2 cubic feet, and weighs 300 pounds ; a bag contains about 7/8 cubic feet, and weighs about 75 pounds.

Use 1 part cement, 2 parts sand, 4 parts aggregate (gravel or crushed stone), for very strong and impervious work.

Use 1 cement, 21/2 sand, 5 aggregate, for ordinary work requiring moderate strength

Use 1 cement, 3 sand, 6 aggregate, for work where strength is of minor importance.
