constituent of which was a gray material, 

 probably limestone, not altogether unsightly 

 after the surface layer of tar had disappeared. 



Tar and other paths made of impervious 

 material should not be flanked by impervious 

 tiles, or water will collect at their sides. 



Cement Paths — These are unsympathetic 

 in colour and Hable to crack under the influence 

 of frost. To guard against cracking a good 

 proportion of sand should be used in mixture, 

 and the path should be laid on a concrete basis 

 at least six inches thick. Cement may be 

 coloured with iron oxide (red ochre) to give it 

 a warmer and more genial hue. 



Brick Paths — Next to gravel the brick path 

 holds first place: indeed, in my opinion, it is 

 preferable to a gravel path in most circum- 

 stances, its only drawback being its want of 

 flexibility, which unfits it for use in curved 

 fines. Its advantages are the ease with which 

 it may be kept free from weeds, its durability, 

 good colour, and the opportunity it off"ers for 

 artistic eff"ect. In gardening, the old order of 

 things dies hard, and gardeners are shy of adopt- 

 ing anything savouring of novelty. Yet the 

 brick path is not altogether a thing of to-day.
