In Maclura aurantiaca. Fig. XLL, roots are formed between the wood. Pig.

In Cydonia japonioa, if we out the roots thesize of a pen into pieces 2 or 2^ inches long, and plant themupright, we shall have the same year as many plants as there werepieces planted. These cuttings should be made in the open air, along aborder or strip of peat, without any other covering than the soil wherethey are to grow. If we plant them vertically, we should cover themvery slightly with earth; and at the first watering the cut will beuncovered. If we place them horizontally, they should be coveredwith earth about i of an inch deep. This last method succeedsequally well, but it is less certain than the first. Mons. Neumannsexperience has also showed that even Conifers may be struck frompieces of the root, concerning which he makes the following six years he had ma
