worth 60 to 70 cents per kilo in Holland; in 1904 a lot of a

Artocarpus elastica is a stately tree with a trunk 60 to 90 
centimeters in diameter. The leaves are alternate, crowded, 
obtuse at both ends, occasionally lobed towards the apex, the 
larger ones 20 to 30 centimeters wide, and 60 to 90 centimeters 
long. The male spikes are cylindrical, oblong, soft or spongy, 
and yellowish. The female heads are somewhat rounded or 
elliptical. The fruit is heavy, at least 10 centimeters long, and 
covered with brownish, hairy appendages. The seeds are em- 
bedded in a whitish, more or less gummy pulp of a delicious, 
tart flavor. They are about the size of peanuts, are eaten 
roasted, and in flavor also resemble peanuts.
