Cenotajjhs, as every one knows, are monuments put up to the memory of 

 persons who are inten-ed somewhere else. They commonly consist of tablets 

 with inscriptions, medallions, busts, basso-relievos, or other sculptural objects, 

 and are very fit ornaments for affixing to walls under cover, or protected by 

 architectural projections, such as those furnished by a chapel, a cemetery 

 veranda, a boundary wall, or a structure erected on purpose, as is not unfre- 

 quent in the French and German cemeteries. 



Walls, when used as the boundary of a cemetery, and built of brick, may be 

 carried up hollow, which will be a considerable saving of material, and render 

 all piers unnecessary, unless for effect, or, in the case of cemeteries laid out 

 in imaginary squares, the piers which are to contain the stones having the let- 

 ters and numbers. 



The main conveying-drains of a cemetery, if built of brick, should be barrel- 

 shaped, in the usual manner ; but, if of stone, the bottom should be laid with 

 flag-stone, and the same description of stone should be used for the covering. 

 Main collecting-drains may be formed by semi-cylindrical tiles placed on flat 

 tiles in the bottom, and small stones placed over them to within a foot or less 

 of the surface of the ground. Surface collecting-drains may be 20 in. deep, 

 formed like the last, with tiles at the bottom, and carried up to the surface with 

 small gravel, finishing with coarse sandj and, 

 when these drains are in the green alleys, grass 

 may be sown over them. When at the sides of 

 the gravel walks or roads, they ought to com- 

 municate with surface gratings at regular dis- 

 tances ; and immediately under each grating 

 there ought to be a pit 1 ft. square and 2 ft 

 deep to retain the sand carried in by the water 

 {fig. 36.), this sand being taken out once a year. 

 Where the roads and walks are laid with as- 

 phalte, gratings of this kind will be more ne- 

 cessary than when they are made of gravel, as 

 a certain proportion of the water always sinks 

 through the latter material, but none through 

 the former.
