Mr. J. J. Bradbery temporarily joined the staff of tlie department,. 

 his planting knowledge peculiarly fitting him for the work. Another 

 change was also initiated ; the half herring-bone had always been to 

 the right of the drainage channel ; but from 1914 as far as the bark 

 of the trees permits, it has been transferred to the left. 



Block I, as now constituted contains trees numbered between 23 

 to 416, and intercalations numbered, 1289, 2143 to 2145, 2160 to 2189, 

 and 2505 to 2508. The trees with numbers up to 416 were planted 

 in 1884-1887, except No. 362 and the intercalations which are much 

 younger. Losses by death have been considerable in it. Of the now 

 standing older trees, rather more than one half were tapped before 

 1904, seventeen were tapped by Mr. Burgess, in 1905 and five were 

 tapped in the group called U. Very few trees escaped tapping in 

 1904, and those that were tapped fell into every possible group of 

 tapped trees. Of the few trees which were not tapped in 1904, most 

 were tapped in 1905 in one way or another and later (if tapped by 

 Mr. Burgess) incorporated in a rotation. The trunks are much 

 burred and tapping is now difficult. The block is on the left of 

 the path in the lower figure of plate opposite page above. 



Block 2, contains trees numbered 2509 to 3CO4, 30lOto 3042, 3045 

 to 3048 and 3051 to 3052. All were planted in the year 1904 and so 

 are eleven years old. None were tapped before 1913, when they 

 entered the rotation under the number II, which in the tables I and 2 

 is indicated by the letter Q. In 1913 groups of trees received 

 artificial manure in different ways, and the whole block was limed as 

 a preparation. Except for the manuring, in age and treatment all 

 the trees are exactly alike ; they are evenly spaced, the lines inter- 

 sected by ditches. 



Block 3 contains trees numbered 832 to I2II with the exception 

 of trees 998 and 999, and contains also 2132, 2140 and 2141, 2134, 

 2137 to 2139, 3006 to 3008 and 2043 to 3049, as well as a few yet some 

 way from flowering and not yet numbered. The trees with the lower 

 numbers were planted in 1887 both rather irregularly and very much 

 too closely. Only two of the now standing trees were tapped before 

 1904. A considerable number were tapped by Mr. Burgess (48) and 

 the Director (20) in 1905. About one hundred went into rotation K, 

 and nearly eighty into rotation J. At first no trees went into the 

 rotations lettered B, C and D ; but when trees were wanted to replace 

 deaths in these some of them were taken from this Block. Very few 

 went into G. In a general way it may therefore be said that the 

 tapping of the block commenced only in a small way in 1904, chiefly 

 in the rotation J, and a little in F, and that of the many trees un- 

 tapped in that year, most were tapped either by Mr. Burgess or Mr. 

 Ridley or in rotation K in the next year. In 1907 there was a 

 fresh distribution of the trees not in any rotation, some going to 

 rotation M, and others to various of the rotations and in 1907 another 

 distribution occurred. The number of trees which have died is 

 proportionately half of that in Block I.
