the amount of Nitrogen removed by the pruning is considerable. 

 Burning should in every case be resorted to to get rid of prunings 

 if blights are prevalent in the garden. The most dangerous in 

 this connection are red rust and thread blight, but one does 

 not know how many others are carried by means of their burial. 

 To leave prunings lying about in a garden with these blights on 

 them is suicidal, and to bury them is dangerous. If the garden is, 

 however, free from blight there does not seem any absolute reason 

 against burying the light prunings and these only provided the 

 following conditions are adhered to : 



(1) They must be buried deep. At least six inches of soil 

 should be left on top of them, so that they will not be turned 

 up by the hoe. 



(2) They should be buried immediately on pruning or as soon 

 after as possible. In Ceylcn trenches are dug to receive the 

 prunings before the bushes are touched at all, and the prunings 

 are put into them practically at once. Once dried up much of the 

 manurial value has gone, or is rendered less available. 



(3) They should be. buried with something which will destroy 

 any latent germs or spores of fungi which are upon them. The 

 best materials for this are Lime and Basic Slag, which not only 

 cause the blight spores to be destroyed but also the prunings to 

 rot more quickly. The usual way of applying the Basic Slag, 

 which is preferable, is to dust it over the buried prunings from a tin 

 in which holes have been made, and immediately cover up the hole. 

 In this way 4 to 5 cwts. would be applied per acre, and in Ceylon 

 the method coupled with a more complete manure on the surface 

 the following spring has been said to be eminently successful. 



If conveniently situated, the burial of jungle provided it does 

 not contain thread blight would be advantageous on heavy soils. 

 It should be put in in trenches, and lime or basic slag added as 

 suggested in the cases in which burial of prunings is admissible. 



BASIC SLAG IN COMBINATION WITH GREEN MANURING. 

 The abovecourse can only be recommended in blight-free gardens, 

 and in general, the method which follows would probably be a better 

 way of applying Basic Slag. Instead of burying this with prunings, 

 broadcast it on the surface, either at the autumn deep hoe (which 

 is preferable) or with the first spring hoe, and then follow with a crop 

 of mati kalai in May, to be hoed in in June, The green manuring
