Blocks 4 and 5 are parallel to one another, and contain trees 

 diverse in age. At the south and north ends of block 5 are irregu- 

 larly placed old trees, the middle part being occupied by isolated 

 older trees among young trees which except for unreplaced deaths 

 are fairly regularly placed. The numbers lie between 435 and 686, 

 830 and 831, 1290 and 1681 excluding 1480 and 1674 to 1678. The 

 older trees, those with numbers between 435 and 686 were planted — a 

 few in 1884, the majority in 1887 : trees 830 and 831 are of 1887. 

 Exact records are lacking in regard to other trees, but their ages 

 vary greatly. Very many trees have been lost from among the oldest. 

 Of those still standing, only four were tapped before 1904. In that 

 year about thirty went into rotation D, rather more into rotation F, 

 twice as many into rotation G, and a few into J. In 1905 a few trees 

 were tapped by Mr. Burgess. In 1909 nearly one hundred and twenty 

 trees were put into rotation N. At the present date there are 

 many trees still unripe for tapping. 



Block 5 bears trees numbered between 687 and 828 with the 

 exception of trees 809 to 819, and again between 1674 and 1996 

 except 1843 and 1844. There are many more old trees on the block 

 than on block 5, the lower numbers among them being all recorded 

 as planted in 1887. The planting is more irregular than anywhere 

 else, and a large number of Casuaiinas, Lagerstroemias, Sagos and 

 Caryotas have been left intermixed until lately. Death has occurred 

 •extensively among the older trees, and especially from wind. Only 

 one of the still standing trees was tapped before 1904. In 1904 sixty 

 of the trees went into rotation F, G and J. In 1905, Mr. Burgess 

 tapped a dozen other trees. In 1906 a few trees were tapped in 

 TOtation K, and in 1907 a few more in rotation M. One hundred 

 more came into tapping in 191O, in rotation N and P. While over 

 the years 1905 to 1912 various trees went into all the rotations except 

 B and C for the replacing of others that had died. The tapping of 

 the block has therefore been very diverse. 



Block 6 is a small area with a slight slope containing all that are 

 left of the oldest trees, intermixed with a great variety of other trees ; 

 In fact it is not a rubber block. The trees are numbered between I 

 and 20, 1287, 2130, 2306, and 2826. The old trees had a variety of 

 tapping, being the first used experimentally. 



Block 7 like the last is not a rubber block, but contains scattered 

 trees of Hevea, which bear the numbers 1220 to 1231, 1843 to 1844, 

 i860, 21 14 and 21 15, 2348 to 2350. They were seedlings either from 

 seed beds or self sown. Several were tapped in 1907 as experiment 

 W versus V, and then they went in 1909 into rotation M, where 

 also others not tapped in the experiment were placed. 



Adjoining block 5, with block 7 on its south side and block 12 

 ■on the east is a part of the Lower Garden kept under sago for the 

 present, which will be used for rubber cultivation soon, and will then 

 be divided into four blocks, Nos. 8-1 1. Scalttrtd rubbtr trees have
