It has remained for Mr. H. Vince, of Bridgewater-oa-Loddon, to- 

 show how the motor cycle may be utilized as an improvised motor spray 

 pump. Mr. Vince's motor cycle is an ordinary 3I h.p. machine, and 

 when utilizing the power for spraying purposes, it is attached to a wooderv 

 triangular frame in such a way that it can be easily disconnected ; at 

 the same time, this frame gives a solid bed to prevent excessive vibration. 

 The cycle wheels, handle bars, and saddle are removed, to prevent oil 

 and caustic sprays from damaging them. The machine is then fitted on 

 to a two-wheeled dray, along with an ordinary barrel spray pump. The 

 pump is driven by a belt off the engine pulley, over the large wheel which 

 is shown in the illustration, the axle of which has a crank which works 

 the pump. 



Mr. Vince uses a fan, cut out of a piece of tin, and attached to the 

 outside of the engine pulley, to keep the cylinder cool. The cycle is 

 covered with a tarpaulin, when necessary, to prevent any spray material 

 from settling upon the various parts. 



Mr. Vince's orchard has an extent of upwards of 60 acres, and the 

 whole of his spraying is done with the motor cycle power. The machine 

 works at a pressure of from 150 to 180 lbs., and the motor will run all 

 day with but little attention. Tt can be disconnected in a few minutes, 

 and again shortlv transformed into a motor cycle. 



By this ingenious means, not only is the spraying done more expedi- 

 tiously, but the drudgery of hand pumping ,is done away with, and the 

 labour of one man is saved ; it requires but two men to attend to the 

 horse and machine, and to do the spraying. 



PROPAGATION OF FRUIT TREES.

Top or Head Grafting. 



This mode of grafting is largely practised upon the apple in the 

 nursery row. If a variety does not sell by the time the young trees are 

 two years old from graft or bud. the operator, by heading them off first 

 below the branches and adopting this method, may have another tree of 

 a desired variety within six months. 



Top graft the young trees about 18 in. above ground level. A top graft 

 put on in the spring is equal bv the following winter to a two-year-old 

 tree from bud. Fig. 43 shows a young tree so treated carrying a graft 

 with five months' growth (defoliated). The variety is Rome Beauty. 



When selecting scions for this method, see that they carry all wood 

 and not bloom buds so as to form a uniformly branched head (Fig. 43). 

 In Fier. aa a scion carrying three bloom buds and one wood bud has been 

 used ; consequently, a tree with a poor head growth is being formed. 

 Consequent on this the wood bud is breaking away and drawing the 

 sap. This reduces the elaboration of sap to the bloom buds and causes 

 the fruit to set. The probable result will be a short lateral growth shooting 

 forth from the bloom spur during the summer (Fig. 44). 



The reformation of such a type and the bringing about of uniform head 

 conditions, by pruning, will depend solely upon the wood growth having 

 suitable buds at the base on which to operate. That part of the scion, 

 and also the strong oblique growth, should be hardened back to the basal
