ANALYSIS OF FEED WATER.
In response to a generous offer made by a leading engineering journal, the following compositions of feed water were ascertained and published. The “Directions” show how the water was forwarded, and the tables, the result of careful examination, of samples sent from widely separated sections of the country.
Directions.
1. Get a clean gallon jug or bottle and a new cork (or, at all events, a thoroughly clean one).
2. Wash out the vessel two or three times with the same water that is going to be sent in it. This is to make sure that the sample may not be contaminated with any “foreign” ingredient.
3. Tie the cork, after the bottle is filled with the water, with a strong string or wire. Pack the bottle so secure, with hay or straw, sawdust, or newspapers, that it may not knock itself to pieces against the sides of the box.
