of the leaf as well a? in the centre, 2 have produced inferior fruits 

 cracked near the base and exuding gummy matter which at- 

 tracted large quantities of the black stinging ants, these fruits are quite 

 useless; 3 have produced little knobs; the remainder of the plants are 

 just commencing to fruit, but are not sufficiently advanced to enable us 

 to form an opinion as to the quality. * 



" Of the 27 plants with the marking on the outside of the leaf, only 

 7 have produced little knobs, 11 have simply grown with the leaves 

 twisted round in the centre of the plants and developed side suckers as 

 though they had fruited ; 4 have produced fruits which were of fair 

 quality, although very small ; and 4 plants produced small bad fruits, — 

 cracked and exuding gum. 



" The greatest care shonld be taken to propagate plants from those 

 having the red colouring matter well developed and in the centre of the 

 leaves only ; plants with faintly coloured or colourless leaves, or plants 

 having leaves with the red colour on the edge of the leaves, should be 

 avoided. 



" Red Ripley : Since observing the variation in the colouring of 

 the Green Ripley Pine Apples, I have also noticed that something ot 

 the same kind occurs in the Red Ripley. When the colouring of the 

 leaves is particularly bright, and the leaves have not the fine bloom 

 observable in the best type of plant, it often produces an abortion 

 similar to those produced by the green variety when badly marked." 



Manures. — Mr. F. Watts, suggested various manures for trial with 

 Pine Apples. The plan was as follows : — 



Manures applied to Pine- Apples, 

 Series A : Size of plots, 18J square yards each. 



Plot 



Manures: Number of pounds 

 per acre. 



Manures : amount in ounces 

 applied to plots.
