For these tliirteeii trees the mean height is 74 feet, and the 

 nieaii girth, at three feet from the ground, is 4 feet 2 inches. 

 This gives a mean annual growth in height of 7 feet 3 inches, 

 in circumference of 5 inches, and in diameter of 16 inch. 



The best grown of these trees is A, which has a trunk of 21 

 feet to the first branch, its diameter being, at three feet from 

 the ground, 14 inches; at six feet 12| inches; and at twenty- 

 one feet, IH inches. This tree is in between others which 

 liave, by shading and crowding it, induced it to grow up 

 straight and branchless. 



The greatest difficulty in planting Para is the very short 

 time which the seed remains good after it falls from the trees. 

 The time which elapses before they are planted should not under 

 any circumstances be longer than a week, and if they can be 

 planted before this so much the better. Sown at once nearly 

 all germinate, but each day which intervenes increases the 

 number of failures, till at the expiration of ten days or so 

 none grow. 



The trees are very prolific seed bearers. Those in the 

 Museum grounds have this year yielded nearly 14,000 seeds, or 

 to speak more correctly, that number have been collected. Most 

 of the trees are planted by the side of a large ditch, and all the 

 seeds which fall into it are at once carried away as they are very 

 light and float on the water. The seeds have been distributed, 

 3,000 given to the Jebong Estate and 11,000 to the Sam Sing 

 Estate. 



At fifteen by fifteen feet 14,000 seed would be enough to 

 plant 72| acres of land. Where the land is ready it is certainly 

 an advantage to plant the seed at stake, but where this cannot
