Trees on the lot are a valuable asset, though dislike for sacrificing them, if carried too far, may result in shutting out the sunlight that is more essential than shade to health. Cottonwood, willows, and even the pretty catalpa are to be shunned in the interest of tidiness. On a 50- or even a 100-foot lot we cannot have many trees without overshadowing the house. A few away from the building, not crowded together, will give more satisfaction than a grove and be less a detriment to health. Ordinarily grass will not grow to advantage where there is much shade; and a beautiful lawn, though open to the sunlight, is not only more attractive but much more serviceable than ground in heavy shadow and covered with sparse grass.
