120 THE KITCHEN-GARDEN. [CHAP. VX. 



laying it down should be sifted, and all stones 

 larger than a moderate- sized gooseberry should 

 be thrown out or broken; and, as soon as it is 

 laid down and evenly spread, it should be well 

 rolled, previously to which, if it should be very 

 dry, it ought to be sprinkled with water. If 

 the gravel be at all loose, it should be mixed 

 with equal parts of brick- dust and Roman 

 cement before laying it down, or the gravel 

 may be mixed with burnt clay .powdered, in 

 the proportion of one wheelbarrow full of clay, 

 to a two-horse cart-load of gravel; or if the 

 gravel be already laid, and it is wished to 

 render the walk more firm, powdered burnt 

 clay may be strewn over it, and raked in. In 

 all these cases, the walks must be watered to 

 consolidate the mixture, and the following day 

 heavily rolled. Sometimes the clay is mixed 

 with water before applying it to the gravel. 

 Where good gravel cannot be procured, tolera- 

 bly firm walks may be made of sea gravel, or 

 powdered sandstone, or even of sand, by this 

 treatment. The clay may be burnt by making 

 it into a heap, intermixed and surrounded with 

 faggot-wood ; or, as a substitute for burning, it 

 may be dried by spreading it on the top of the 

 furnace or boiler employed to heat the hot- 

 houses. 



When the walks in a kitchen-garden are 

 formed of flag-stones, artificial stone, or brick, 

 the material used is laid on brick arches or 

 piers ; and when grass walks are employed, 

 they require no other preparation than marking 

 them out on the ground, consolidating it by 

 pressure, and then laying them with turf.
