130 FRITZ BAHR'S COMMERCIAL FLORICULTURE 



concrete will be sufficient. In a heavy soil you cannot provide too 

 much drainage and, in addition to the cinders, it won't hurt to lay a 

 3-in. tile drain 18 in. below the finished side grade of the drive filling 

 the ditch up with cinders. 



You may want to hire a concrete man to do your first job, but 

 there is no reason why in time your own men cannot do that work 

 and also the resurfacing of old driveways with Tarvia and screenings. 

 A tar heating outfit will soon pay for itself and as long as there are 

 drives there will be work to do on them. You don't need all those 

 things to start out with, but if you go on and find not only that there 

 is good money in this kind of work, but that it is becoming interest- 

 ing, as all constructive work is, you will soon get everything necessary 

 in order to do efficient work, and do it with the least effort. 



Cinder and Crushed Stone Construction 



In order to hold up an automobile (and there is no use building 

 a drive for anything less heavy today) you need at least a 4-in. layer 

 of cinders and 6 or 7 in. of coarse stone with enough Umestone 

 screenings to bind all of the interstices. After these are spread 

 the whole should be flushed with water and rolled with a roller heavy 

 enough to produce a firm and even surface. To be finished properly 

 such a road should have a good coating of Tarvia and screenings. 

 This wiU keep the water out, but, after all, the cost is not much less 

 than that of a concrete one. 



The main walk leading from the street to the entrance of a 

 residence is next in importance, and if laid out to run up straight 

 from the street sidewalk, it usually means cutting the front lawn 

 in half, which should never be done with a walk straight through the 

 center of the lot. If a walk is wanted — and this is necessary in the 

 case of the absence of a drive — suggest one with a long, graceful 

 curve, but never with a reversed curve in the shape of a letter S. 

 The walk should enter at one side, run for a little way almost at 

 right angles to the street sidewalk and then curve gently toward the 

 front entrance with a group of shrubs or conifers near the point 

 where it starts to lead to the entrance. This planting should mask 

 either end if viewed from the other. Never have such a walk so 

 that you can see both ends of it at the same time. 



The Elements of a Lawn 



While the planting of trees and shrubs is, perhaps, next in order 

 after the grading has been completed and the drive and walks have 

 been located, we will take up the lawn for a few minutes for it comes 

 next in importance and consideration. What would all the trees, 

 shrubbery and flowers on a place amount to if there was no lawn as 

 a background ? To my mind, a fine sweep of turf is of the very first 

 importance.
