INSTRUCTIONS FOR SELECTING SAMPLES FOR ANALYSIS.
Mano-ass.
Any method of sampling mutually agreed upon between buyer and
seller may be adopted, but the following method is recommended as
a very complete and satisfactory one: Four or more bags should be
selected for sampling. Each bag is to be emptied out separately on a
clean floor, worked through with the spade, and one spadeful taken
out and set aside. The four or more spadefuls thus set aside are to
be mixed together until a uniform mixture is obtained. Of this
mixture one spadeful is to be taken, spread on paper, and still more
thoroughly mixed, any lumps which it may contain being broken
down with the hand. Of this mixture two samples of about half a
pound each should be taken by the purchaser or his agent, in the
presence of the seller 01‘ his agent or two Witnesses (due notice having
been given to the seller of the time and place of sampling), and these
