THE TECHNICS OF GARDENING. 143 



can graft and bud. Or why should not scarlet oak 

 and scarlet acer be grafted on common species of 

 these genera along the margins of woods and planta- 

 tions ? 



In planting, the gardener has regard for character 

 of foliage and tints, the nature of the soil, the un- 

 dulations of ground and grouping, the amount of 

 exposure. Small plantations of trees surrounded by 

 a fence are the best expedients to form groups, says 

 Repton, because trees planted singly seldom grow 

 well. Good trees should not be encumbered by ped- 

 dling bushes, but be treated as specimens, each having 

 its separate mound. The mounds can be formed out 

 of the hollowed pathways in the curves made be- 

 tween the groups. The dotting of trees over the 

 ground or of specimen shrubs on a lawn is destruc- 

 tive of all breadth of effect. This is not to follow 

 Nature, nor Art, for Art demands that each feature 

 shall have relation to other features, and all to the 

 general effect. 



In planting trees the variety of height in their 

 outline must be considered as much as the variety of 

 their outline on plan ; the prominent parts made 

 high, the intervening bays kept low,* and this both 

 in connection with the lie of the ground and the 

 plant selected. Uniform curves, such as parts of 

 circles or ovals, are not approved ; better effects are 

 obtained by forming long bays or recesses with forked 



" One deep recess, one bold prominence, has more effect than 

 twenty little irregularities." " Every variety in the outline of a wood 

 must be a prominence or a recess" (Repton, p. 182).
