74 MANUAL OF GARDENING 
In back yards it is often best not to have any well-defined 
walk. A ramble across the sod may be as good. For a back 
walk, over which delivery men are to travel, one of the very 
best means is to sink a foot-wide plank into the earth on a level 
with the surface of the sod; and it is not necessary that the 
walk be perfectly straight. These walks do not interfere with 
the work of the lawn-mower, and they take care of themselves. 
When the plank rots, at the expiration of five to 
ten years, the plank is taken up and another one 
dropped in its place. This ordinarily makes the 
best kind of a walk

bank of foliage which 
breaks up the hard line 
of a walk, and serves also as a border for the growing of 
flowers and interesting specimens. This walk is also character-

trates this fact, and also shows how the parking between the 
walk and the street may be effectively planted.

The borders and groups of planting are laid out on the paper 
plan. There are several ways of transferring them to the 
ground. Sometimes they are not made until after the lawn is
