 ditions as they exist, and then to determine the method of procedure best suited 

 to the conditions before any actual work is begun. Too many home sites are

Simplicity is the key note of perfection. Let the grading, as well as tlic

 and thus create an artificial appearance ; but to utilize the suggestions that nature
