Bomkolz, M. Alex, de, translated from the German, by M. Mich. Egger : De 



la Culture des Truffes, ou Maniere d'obtenir, par des plantes artificiels, des 



Truffes, noires et blanches, dans les Bois, les Bosquets, et les Jardins. Paris, 



8vo. 



The truffle, the author regards as superior to all other fungi as an 

 esculent ; according to him, it is a production both of an animal and 

 vegetable nature ; not propagated by seed, but generated in a manner pe- 

 culiar to itself, under layers of earth, peculiarly situated, in the same way 

 as certain worms are formed in the flesh of animals. Hence the manner of 

 propagating the truffle is not the same as that of propagating the mushroom. 

 Finding the truffle most commonly in grounds where there were oak trees, 

 he recommends a soil composed chiefly of rotten oak leaves and bark, into 

 which he proposes to plant the truffle from its native habitation, and leave 

 it to encrease by those sort of offsets, which, he says, it produces when full 

 grown. He proposes to establish truffle-grounds in the glades of park and 

 pleasure-ground scenery, guarding them from such animals as the hog, stag, 

 fox, squirrel, &c. which search for and devour them ; and destroying, as far as 

 possible, worms, snails, beetles, and other insects which live upon them. 



Five species are described, all growing most frequently in thin oak 

 woods; sometimes in mixed woods of deciduous trees, but never under 

 evergreens, especially the pine and fir tribe. As far as our own ob- 

 servation has gone, the truffle is most frequent in England in scattered 

 beech-woods ; but it is also met with in abundance in open commons, where 

 there are no ligneous plants, excepting furze. Three species are natives of 

 Britain, and as they grow wholly under the surface of the ground, they are 

 discovered by watching where hogs dig for them, and by small dogs trained 

 on purpose to scent them.
