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.
