Concrete, etc., for Floors, Borders and Walks, continued. 



For Walks. — Walks should always have a well-made 

 foundation of stones or brickbats to give hardness and in 

 sure drainage. The top of the walk may be made of gravel, 

 sifted coal-ashes, cinders from foundries, furnaces, etc. If 

 gravel is used, care should be exercised to avoid the round 

 or washed gravel, particularly that lying in the beds of 

 streams, for it will not pack. One part of clean clay to 4 or 

 5 of gravel makes a good walk. Or the following may be 

 used: 



1. One part mineral pitch, 1 part resin, 7 parts chalk and 

 2 parts coarse sand. Boil together, and lay it while in a hot 

 state, adding a little gravel. 



2. Boil for a short time 18 parts of mineral pitch and 18 

 parts of resin in an iron kettle ; then add 60 parts of coarse 

 sand ; mix well, and lay on the path to the thickness of 1 in. ; 

 then sift a little fine gravel over it. and beat it down before 

 the cement sets. 



3. Put down a coat of tar and sift some road-sand or coal- 

 ashes over it very thickly. When this is dry repeat the oper- 

 ation until you have 4 coats of tar and as many of coal-ashes 

 or road-sand. 



4. Two parts of thoroughly dried sand, 1 part cinders, 

 thoroughly dried. Mix together ; then spread the sand and 

 cinders on the ground and make a hole in the center, into 

 which pour boiling hot tar and mix into a stiff paste ; then 

 spread on the walk, beat and roll. 



5. Two parts lime rubbish and 1 part coal-ashes, both 

 A'ery dry and finely sifted ; in the middle of the heap make 

 a hole; into this pour boiling hot coal-tar; mix to a stiff 

 mortar and spread on the ground 2 or 3 inches thick. The 

 ground should be dry and beaten well. Cover with coarse 

 sand; when cold, roll well. 



3. Paints and Protective Compounds.— 



Home-made Washes for Fences and Out-buildings may 

 be made by various combinations of lime and grease. The 

 following are good formulas : 



1. Slake fresh quick-lime in water, and thin it to a paste 

 or paint with skim-milk. The addition of 2 or 3 handfuls of 

 salt to a pail of the wash is beneficial
