Alcohol is distilled from nipa, coco-nuts, burs (Corypha umbraculifera), cauong (Caryota onusta), pugahan (Caryota urens) and Indian corn.
At one place we find drifted fruits of Nipa, at another Hightea and Anona.
It has important fisheries, and manufactures salt, pottery, roofing (made of nipa leaves), and nipa wine.
In these marshes grows the nipa palm, from which a liquor is distilled - there are a number of small distilleries here.
North of San Nicholas is Tondo, the most densely populated district; in the suburbs, outside the fire limits, the greater part of the inhabitants live in native houses of bamboo frames roofed and sided with nipa palm, and the thoroughfares consist of narrow streets and navigable streams. Paco, south-west of Intramuros, has some large cigar factories, and a large cemetery where the dead are buried in niches in two concentric circular walls.
More than one half of the dwellings in the city are mere shacks or nipa huts.
Nipa, made from the fibre of the agave or maguey plant and worn by women, is less common.
Macabebe's principal industries are the cultivation of rice and sugar cane, the distilling of nipa alcohol, and the weaving of hemp and cotton fabrics.
Flora and Faunx.-Although the vegetation of the Nicobars has received much desultory attention from scientific observers, it has not been subjected to a systematic examination by the Indian Forest Department like that of the Andamans, and indeed the forests are quite inferior in economic value to those of the more northerly group; besides fruit trees - such as the coco-nut (Cocos nucifera), the betel-nut (Areca catechu), and the mellori (Pandanus leeram) - a thatching palm (Nipa fruticans) and various timber trees have some commercial value, but only one timber tree (Myristica irya)would be considered first-class in the Andamans.
Callitris (2 species), Sequoia, Athrotaxis (?) Ginkgo, Podocarpus, Pinus; and several genera of palms, of which the tropical Nipa is the most abundant and most characteristic, among the others being fan-palms of the genera Sabal and Chamaerops.
On the south coast must also be named Bonthain (4000); on the east coast, Balong-Nipa; and Buton and Saleyer, seats of administration and ports of call on the island groups of the same names.
The remains of palms (Sabctl and Nipa) as well as of other large-leaved Monocotyledons are preserved.
