at bottom than at top ; but for particular purposes, such 

 as that of growing hyacinths, pots are made almost 

 equally wide throughout, and deeper than usual in pro- 

 portion to their width. For striking cuttings, or grow- 

 ing seeds, there are pots made broad and shallow, some- 

 times called pans or store pots. There are also pots for 

 aquatics, made without holes in the bottom to permit 

 the escape of water ; others for marsh plants, without 

 holes in the bottoms, but with holes in the sides half way 

 between the bottom and the top, so as to retain the 

 lower half of the soil in a marshy state. There are 

 pots made with a slit on one side (fig. 52), for the pur- 

 pose of introducing the shoot of a plant to be ringed in 

 order to cause it to produce roots (a small wooden 

 box is much better, as being less porous) ; others with 

 a large hole in the side for the same purpose ; some 

 with concave bottoms, with the intention of putting the 

 water hole out of the reach of worms (figs. 53 and 54) ; 

 others (fig. 55) with grooves in the bottom to prevent 

 the retention of water by the attraction of cohesion, 

 when the pot stands on a flat surface ; and there are 

 pots fixed within pots, so that the space within the outer 

 and the inner pot shall be water-tight, in order to con- 

 tain water or moist moss, so as to keep the soil hi the 

 inner pot of comparatively uniform moisture and tem- 

 perature. There are pots made in two parts (fig. 56), 

 the lower serving as an ornamen- 

 tal base so as to give the pot a 

 somewhat classical character and

 the pot. Pots are also made with rims pierced with 

 holes, so as to construct on them a frame of wirework 

 for training climbers, as in fig. 57. There is also what 

 is called a blanching-pot (fig. 58), which is placed over 

 plants of sea-cale, rhubarb, c., for blanching them, Fi - 58 -
