The correlation of this weight with the weight of copra is higher than that between weight of copra and the number of nuts (1). [...] But here too grave errors may be introduced by the progressive desiccation of the husk which loses a considerable amount of water on storage in heaps on the field; so that it would be risky to attempt to establish a definite numerical relation between the weight of unhusked nuts and the weight of copra since this relation would alter with varying degrees of dryness of the husk. [...] The third method of expressing yield is by making use of the weight of husked nut; and it is the purpose of this paper to show that this is the most satisfactory and least troublesome method of arriving at a reliable expression of yield. [...] 11 on the other hand the former material is smaller one edge of the wedge ihould he slightly narrower than the other and when inserted into the cleft The -narrower side is placed toward the centre of the stock. [...] Observations show that the nature of the protection should vary according to the time of the year at which the graft is made.
