INOCULATING. 



from the parent, and the stock is cut 

 over a little above the graft. After some 

 further time, -when the scion begins 

 to grow vigorously, the stock is cut 

 close over above the point of union, 

 and the section left becomes in time 

 covered with bark. Inarching is only 

 adopted in the case of woody plants 

 that grow with difficulty when grafted 

 in the usual manner. The conditions 

 of growth are the same as in inde- 

 pendent grafting — viz. that the inner 

 or soft wood of the stock must be 

 placed exactly on that of the scion, to 

 ensure their union. Inarching is ge- 

 nerally applied to Camellias ; and any 

 person who has visited Messrs. Lod- 

 diges', at Hackney, Messrs. Chand- 

 ler's, in the Vauxhall-road, or, in fact, 

 any of the great Camellia growers, in 

 April or May, must have seen some 

 of the large old plants of the superior 

 kinds, surrounded by a number of 

 pots of the common single red, sup- 

 ported at different heights, for the 

 convenience of reaching the different 

 branches to which they have been 

 united by inarching. The mode of 

 grafting shown in fig. 21, in p. 129, 

 has all the advantage of inarching, the 

 scion being nourished by the water 

 in the same way as it would be by 

 its roots, in the case of inarching.

Indigo is formed from the leaves of 

 an Indian plant, called Indigofera 

 tinctdria, belonging to the order Le- 

 guminosce, and it requires a stove in 

 England. The false Indigo, Amor- 

 pha, also belongs to Leyuminosce ; 

 and some of the species are hardy 

 shrubs or low trees. See Amo'rpha. 



Inga Leguminosce. — Beautiful 



plants, nearly allied to the genus Mi- 

 mosa, with silky, tassel-like flowers. 

 All the species are stove-shrubs, and 

 should be grown in a mixture of loam 



and peat. They are propagated by 

 cuttings, taken off at a joint, and struck 

 in pure sand, under a bell-glass, and 

 plunged in a hotbed or in tan, to af- 

 ford them bottom-heat. 



Inoculating This term, when 



applied to plants, is generally used as 

 equivalent to that of Budding, which 

 see in p. 33 ; but it is also applied to 

 a mode of creating a grassy surface, 

 either for a lawn or a pasture-field, by 

 distributing fragments of turf taken 

 from an established pasture over a 

 newly-formed surface. Supposing the 

 surface which it is intended to form 

 into a lawn, to be levelled, dug, and 

 smoothed, rolls of turf are procured 

 from any suitable meadow or pasture, 

 and cut into pieces, and laid down on 

 the prepared surface at a foot or a foot 

 and a half apart ; and the intervening 

 spaces are sown with grass-seeds, and 

 the whole firmly rolled. The pieces 

 of turf give an immediate character of 

 grassy surface, and they are united in 

 the course of a season by the growth 

 of the intervening grass-seeds. It 

 may be asked, why not use the grass- 

 seeds alone, and save the expense of 

 the turf? the only answer to which is, 

 that the pieces of turf being green from 

 the commencement, anticipate in idea 

 the future effect that will be produced, 

 and make sure of a grassy surface in 

 case the grass-seeds should fail. The 

 practice originated in Norfolk, and it 

 is sometimes adopted in agriculture as 

 well as in gardening. 



Inoculating lawns with mushroom 

 spawn is a practice sometimes adopted 

 in gardens in the country, and affords 

 at once a source of amusement in col- 

 lecting the mushrooms, and of profit 

 from their usefulness in the kitchen. 

 It may be adopted in the case of any 

 lawn, whether old or newly-formed. 

 A few spawn bricks, as they are called, 

 are procured from any person that 

 grows mushrooms, or from the seed- 

 shops ; and these, being first broken
