shoots of this plant, struck from root cuttings, come out romid the root 

 as is seen in Fig. XL. , n. ; this gives the means of splitting the roots into 

 several pieces, which, separately, strike as well as an entire root, Fig. XL. ,

and the bark by an innumerable number of exceedingly minute bulbs, 

 which turn green and produce buds. Cuttings of this plant strike 

 easily in the open air. 'In Cydonia japonioa, if we out the roots the 

 size of a pen into pieces 2 or 2^ inches long, and plant them 

 upright, we shall have the same year as many plants as there were 

 pieces planted. These cuttings should be made in the open air, along a 

 border or strip of peat, without any other covering than the soil where 

 they are to grow. If we plant them vertically, we should cover them 

 very slightly with earth; and at the first watering the cut will be 

 uncovered. If we place them horizontally, they should be covered 

 with earth about i of an inch deep. This last method succeeds 

 equally well, but it is less certain than the first. Mons. Neumann's 

 experience has also showed that even Conifers may be struck from 

 pieces of the root, concerning which he makes the following statement. 

 During six years he had many times tried to strike an Aiaucaria 

 from cuttings of the roots, but without success ; at last, on the 10th May, 

 1844, he perceived that the cuttings of the roots of Aiaucaria 

 Cunninghami, | inch in diameter, and about 2| to 3 inches long, 

 planted in October, 1843, were sending forth shoots, He attributes his 

 failure, up to this time, to the presence of the glasses with which he 

 covered the cuttings : the constant presence of air charged with an excess 

 of moisture making them perish. In the first place, the pots which 

 contained the roots were, in October, plunged into tan still gently 

 warm ; perceiving in March that the earth in the pots was decomposed, 

 he changed it, without being able to distinguish the least sign of 

 vegetation on the euttinga. The pots were then placed upon a bench
