Such a result as is shown for 1870, and the probable result of 27 flushes to the end of that season, could not be obtained without high cultivation and liberal manuring. The land in question had been manured every year since it was planted, but an extra dose was given in the cold weather of 1869-70. The ground was therefore very rich.
I think, therefore, 25 flushes in the season may be looked for on gardens in good Tea climates, when high cultivation and liberal manuring are resorted to. Where manure cannot be obtained, I think, even if in other respects the land is highly cultivated, more than 22 flushes will not be obtained. Where neither manure nor high cultivation is given, above 18 flushes will not be got.
It seems to be a general idea with planters (see diagram, page [104]) that when a flush is picked the succeeding flush, at an interval of say seven to ten days, consists of shoots from the axis of the leaf down to which the previous flush was picked. Thus in the diagram, supposing the shoot to be picked down to the black line above 2, the idea is the next flush will be a shoot springing from the same place, viz., the axis of leaf d. But it is not so. In the above case it will take a whole month, after the said shoot has been picked, before the new shoot from the base of the leaf d is ready to take, probably six weeks in Himalayan gardens.
’Tis true the flushes in favourable Tea climates follow at about seven to ten days from each other, but these are other shoots. The replacement of the actual shoot taken is a whole month in developing. I have carefully watched this, and am sure I am right.
With similar treatment, gardens in Cachar, Assam, and the Western Dooars would probably give two or three more flushes in the season than Chittagong, because there the spring rains are much more abundant; and I am very certain that, if the day ever comes that manure in large quantities is procurable in those districts and is applied, the yield on those gardens will be very large.[33]
The difference between very small and very large profits is represented by 18 and 25 flushes, so I strongly advise all planters to cultivate highly, and to get all the manure they possibly can. If even procured at a high figure, it (the manure) will pay hand over hand.
[CHAPTER XXIII.]
LEAF PICKING.
The first consideration is how to get the largest quantity of leaf without injuring the trees.
To a certain extent, it is true that the more a Tea bush is pruned and picked the more it will yield. It appears as if Nature were always trying to repair the violence done to the tree by giving new mouths or leaves to breathe with in place of those taken away. I may exemplify my meaning in another way. A Tea bush which has as many leaves on it as it requires will throw out tardily new shoots, and their number will be small. In other words, a plant which is not pruned, and from which the young leaves are not taken, grows gradually large and bushy, and then gives up flushing altogether. It has all the leaves it requires, and it has no necessity to throw out more.
