 of the early spring sun to hasten luxuriant bloom. 

 The garden shelters may be so> arranged that shade

 When there is a bit of woodland at one side of the 

 house, it will form an additional barrier against 

 winter winds if the wall is built in its shelter. When 

 the house and garden buildings shelter the walled 

 garden from the northern exposure a similar effect

 enjoyed early in the spring and late in the autumn. 

 Practical garden architects are now giving special

 closure is sometimes noticed where the northern wall 

 is built considerably higher than the others, and a 

 decorative planting of tall evergreens helps to serve 

 as a windbreak while increasing the decorative value. 

 When stone is to be used dry-wall construction
