Dr. Modigliani devotes a chapter to the geography, Dr. Modigliani's choice of the island of Nias as the meteorology, and geology of Nias. The island is hilly, field of his explorations was a singularly happy one, in but can hardly be called mountainous.

Here Modigliani saw palpable proofs at Nias. "Gunong Sitoli is mostly peopled with Malays, of the well-known head-hunting propensities of the Klings, and Chinamen, the trade of the island being Niassers. The big council house, or osald, was adorned chiefly in the hands of the latter. Here, overcoming not a few serious difficulties, Modigliani made his preparations for visiting the southern parts of Nias, freer from external contact, and therefore more interesting; and for this purpose, a Malay boat-pencialàng-was chartered. Whilst these preparations were being completed, Dr. Modigliani visited a large cave near Hili Sabegno, and, besides other interesting animals, collected specimens of a bat (Emballonura semicaudata) previously known only from Polynesia. Meanwhile, his hunters were not inactive, and, amongst other interesting specimens, four new species of birds, a singular new earthworm, and several new insects were collected in the neighbourhood of Sitoli; the birds have been recently described by Salvadori as Gracula robusta, Calornis altirostris, Miglyptes infuscatus, and Syrnium niasense.

Tobacco is the principal article for barter with the wilder inhabitants of Nias, therefore Modigliani provided himself with a large stock, mostly Sumatra grown, and called mussi ; Javanese tobacco, called ginu, has a greater value. He provided himself, besides, with cotton cloth of different colours, and brass wire, also much sought by the Nias people.

At last the pencialang was ready, and Modigliani sailed in her to the south end of the island, and anchored in the Luaha Vára Bay. His first sight of the Nias Southerners

With much pluck and presence of man and a warrior until he has cut off a head; he then mind, Modigliani overcame the momentary anxious assumes the prized calabúbo (Fig. 2), a beautiful collar made suspense, and in a few minutes he was on his way to the ot thin circular sections cut out of the double nut of the village of Bàwo Lowaláni, surrounded and followed by Lodoicea seychellarum (which is often cast by the sea on the excited warriors. Here he soon made friends with the island), neatly strung on a brass wire with a circular Faòsi Aro, the chief, the tallest and most crafty of Southern Niassers, who appeared with two immense earrings resting on his right shoulder. A liberal distribution of tobacco soon made Modigliani popular all round. Bàwo Lowaláni is a good type of a South Nias village, placed on a height and defended by a stout stockade ; the incessant wars between village and village render such precautions necessary. Our traveller passed several days here, having taken up his quarters in the house of Faòsi Aro, built as usual on stout piles ; he was thus able to gather much information on the ways and manners of the Niassers. His Javanese collectors, although much afraid of the natives, who were constantly armed and on the alert, being then at war with two neighbouring villages,

Formerly desired skulls (for his anthropological collection), he of they made singular helmets of rotang and arenga-fibre, course concluded that he wanted to get fresh ones as with beard and mustachios ; now the chiefs are provided trophies, and at once offered to organize an expedition with curious iron helmets, pot-shaped, ornamented with a

large plume or palm-leaf cut in a thin iron lamina, usually gilt; they wear, with this, curious iron spur-like mustachios passing under the nose and secured to the ear. The head-dress of the warrior of "old Japan” was a very similar contrivance ; to complete the parallel I will add that the ceremonial war-jacket, often a regular cuirass in buffalo-leather, pangolin-skin, and scales or twisted rope tissue of tough Gnetum fibres, usually projects widely over each shoulder. It is thus with the war-jacket of some of the Dayak tribes, and was thus with the ceremonial kamiscimo of the Nippon samurai. The Nias shield, balúse, is peculiar, and made in a single board of tough light wood; in the northern parts of the island a heavier one, called dagne, more akin to Bornean and Celeban shields, is used. The characteristic weapons of the Niassers are the spear (tdho) and sword (ballatu), the latter not unlike the Dayak parang. The iron spearheads are generally small and narrow, simple, or more or less provided with barbs; the wood is from the Nibóng palm, and usually ornamented with rings of rotang, brass, or wire, and often with iufts of hair from an enemy's head. The sword is still more characteristic. Its sheath is made with two halves neatly fitted and bound together with plaited rotang ; the big sword (ballátu sebía, "number one") is, especially in the south of Nias, the favourite weapon ; much trouble is taken in ornamenting it, and the
