would answer every purpose better. Any walk that passes the house, and
returns to it, _e,_ is inexcusable unless it is necessary to make a very
steep ascent. If most of the traveling is in one direction from the
house, a walk like _f_ may be the most direct and efficient. It is known
as a direct curve, and is a compound of a concave and a convex curve.

It is essential that any service walk or drive, however long, should be
continuous in direction and design from end to end. Figure 67
illustrates a long drive that contradicts this principle.

It is a series of meaningless curves. The reason for these curves is
the fact that the drive was extended from time to time as new houses
were added to the villa. The reader will easily perceive how all the
kinks might be taken out of this drive and one direct and bold curve be
substituted.

The question of drainage, curbing, and gutters.

Thorough drainage, natural or artificial, is essential to hard and
permanent walks and drives. This point is too often neglected. On the
draining and grading of residence streets a well-known landscape
gardener, O.C. Simonds, writes as follows in "Park and Cemetery ":
