erty with trees of the same age, you cannot afford to have them 

 destroyed and to start in with having a planting of young ones. 

 The next thing is the procuring of a good, strong sod. It 

 is very essential to have the lawn clean. There is but one way 

 to do this, i. e., fix the grade and then let it lie, if you do the 

 filling in the spring, working over the whole surface every two 

 weeks, all summer; by the tenth of September you will have 

 killed nearly every weed, and seed sown at this time is almost 

 sure to "catch," and will become established before the heavy 

 freezing, and a fine, clean lawn will follow the next spring. Or 

 you can fill in and get grade in place in the fall, and let be over

 cultivate all over as soon as dry enough. Rake off and let it be

The kind of grass seed is . of considerable importance. 

 Timothy is always a "sure catch," but it is coarse, and should be 

 used sparingly, if at all. The character of the plant can be seen 

 to the right in Photo 171. The bunch to the left is Kentucky 

 blue grass which is considered the best "all round" grass that 

 can be used on a lawn, though there are finer kinds. Don't use 

 Red Clover ; it is too rank a grower for lawn purposes, as shown 

 in Photo 170. A bunch of the White Clover is shown on the 

 left in that picture ; it is a fine variety for lawn purposes.
