Forlagets beskrivelse
Excerpt from Lead Arsenate: I. Composition of Lead Arsenates Found on the Market; II. "Home-Made" Lead Arsenate and the Chemicals Entering Into Its Manufacture; III. Action of Lead Arsenate on Foliage

Being white, it forms a visible coating and is easily distinguished whenait has been applied.

The initial cost of this material is slightly greater than that of Paris green, owing to the fact that it contains a smaller percentage of arsenic than the latter, and therefore more of it must be used to produce the same effect. Because of its greater adhesive qualities, however, it remains on the foliage better, requiring less frequent application, and thus in the end lead arsenate is no more expensive than Paris green; in fact, it may be even cheaper, as the greatest expense in spraying is the cost of applying the material to the trees.

The use of lead arsenate has increased very rapidly during the last few years, as is shown by the fact that less than ten years ago no one was manufacturing it to any large extent, while at the present time there are at least eighteen manufacturing chemists in the United States making it in greater or less quantities, and a number of other firms are preparing to do so. An attempt was made to determine the total amount sold in the United States for the years 1907 and 1908 by Writing to the various manufacturers for figures showing their sales.
