Brazil Nuts are classified according to sizes, as follows: Large, Large Medium, Oood Medium, and Medium. After purchase the nuts are measured by hectolitre and delivered into lighters, to await transshipment to the ocean steamer. The shelling of Brazil nuts, and theír export, principally to the United States of America, was initiated a few years ago, and is now well established. The volume exported has reached the appreciable total of 668 metric tons, produced by 12,000 to 13,000 hectos. The Brazil nut is singularly fre~ from insect pests, but they are not immune from fungoid growths, some of which are innocuous, while others are insidiously destructive. The fungus establishes itself on the outside shell of the kernel, penetrates the pores of the shell in search of nourishment, and tims by degrees disintegrates the living tissues of the kernel into an evil-smelling fluid of the consistency of puss. The only remedy against this disease is thorough ventilation at all times, so that the nuts are therefore trenched and turned every day while in lighters and during the homeward voyage. Special men are hired for this purpose, and who, like the famous recruiting poster, are able to "see the World and be paid for it." The export of the pods is strictly prohibited by Federal Law, under the conviction that the pod itself is instrumental to the germination of the seeds. This is quite a misapprehension, as we frequently find nuts in process of gerrnination aboard the river steamers and lighters. It is only •
