Moreover, it is quite common, whenApples are pared, to find decayed cells, althoughthere is no external pitting, and in such cases itcan hardly be contended that the malady is dueto external injury from spraying or other agency. fertilising of Apple Orchards. Various dres-sings were applied to the trees in order to ascer-tain their respective effects upon growth of woodand yield and colour of fruit. Farmyard manureand nitrogenous artificial manure alone or incombination notably increased growth andbut reduced colour. The latter is attributed to.

The name bitter pit is not altogether appro-priate, as in many cases there is no discerniblebitterness. The subject is one which stands inneed of thorough research. Colour in Apples. Evidence in support of the old opinion that sunlight is the chief agent in developing colour in Apples is afforded in a bulletin from the Pennsylvania Experiment Station on The delayed maturity and a diminished light supplyto thefruit, due to an increase in the den-the foliage. It is added that experiments pithat exposure to sunlight after picking increasedredness by over 35 per cent., while some of thesame lot of fruit stored in darkness showed prac-tically no deepening of colour. The conclusionis that maturity in sunlight on the trees is un-doubtedly the great influence affecting rednessin fruit. Phosphates, wh
