TBOPJB'OLTOI. Indian Cress. (From 

 tropaion, a trophy. Nat. ord., Indian 

 Cresses [Tropseolaceae], Linn., S-Oc- 

 tandria \-Monogynia.} 



Annuals, by seed in the open ground in April ; 

 tuberous, by division of the roots, and by cuttings ; 

 the others by seeds; also by cuttings in sandy 

 loam any time during spring and summer and 

 early autumn ; a rich, light soil suits them best. 

 The best tuberous kinds multiply their tubers if 

 the young shoots are laid in the ground as they 

 commence growing. A tuber will generally form 

 at the bends : none of them will stand frost, 

 unless the hardy tuberous ones, and they had 

 better be lifted and kept in dry sand until spring.

TROWEL. This implement, made of 

 iron, from twelve to six inches long in 

 the plate, and half as broad, hollowed like 

 a scoop, and fixed on a short handle to 

 hold with one hand, is convenient in 

 removing small plants with a ball or 

 lump of earth about their roots ; lifting 

 bulbous flower-roots after the flowering 

 is past in summer, planting bulbs in 

 patches or little clumps about the borders, 

 for digging small patches, also, in the 

 borders, and sowing hardy annual flower- 

 seeds ; likewise for filling mould into 

 small pots, stirring the surface of the 

 earth in pots, and fresh earthing them 

 when necessary. 



TRUFFLE. Tu'ber magna'tum, Pied- 

 montese Truffle; T. Bo'rchii, Italy; T. 

 moscha'tum, Musk Truffle, near Bath; 

 T. ciba'rium, Common Truffle, England. 

 But, besides the tubers, there are other 

 edible fungi known as truffles, viz., Hy- 

 drobo'lites tula'snei, Spye Park, Wilts; 

 Melagona'ster Broomeia'nus, Red Truffle, 

 near Bath. 



These edible fungi have not yet been 

 cultivated in England, though the Prus- 

 sians have succeeded in making them a 

 garden tenant, and Comte de Borch has 

 been equally successful in Italy. The 

 latter cultivates the Piedmont Truffle, 

 and his process is this : He either em- 

 ploys the soil where the truffle is found, 

 or he prepares an artificial soil of seven 

 parts good garden earth, two well-
