Excerpt from The Hawaiian Forester and Agriculturist, Vol. 4: A Monthly Magazine of Forestry, Entomology and Agriculture, May, 1907On January 11 the four-masted American iron ship E. M. Phelps arrived from Manila. We inspected the ballast on board and found it to consist of dark sand and small shells taken from the beach of Cavite below Manila. We also examined it when it was being discharged, but failed to find any trace of vegetable matter. It was used for cement work in town. Another Ameri can iron ship, the Astral, arrived from Japan on March 4 with clean sand and gravel and was allowed to discharge on the wharf. The inspection of ballast of this nature coming from foreign ports is to prevent the introduction of soil which might contain the larvae or grubs of obnoxious insects.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
