second joint. Some people, who do 

 not know the value of leaves, cut off 

 the side shoots close to the stem at 

 once ; but the substance of the stems 

 and trunks of all trees, and mignonette 

 trees among the rest, is first formed by 

 the leaves. In the second year you 

 will cut off more than the half of these 

 side spurs, beginning at the bottom, 

 and only taking off a pair at a time, 

 and in ten days or a fortnight another 

 couple, and so on progressively. 



There must be no flowers the first 

 season, at least as long as there are 

 some out in the borders. After the 

 middle of October you may let your 

 trees bloom all the winter, but before 

 that nip them off as fast as they ap- 

 pear. When the first little pots are 

 full of roots, say about Midsummer, 

 shift the plants into 5-inch pots, which 

 is the next largest size ; and if they 

 have done well they may want another 

 shift by the end of July, but never 

 shift them after the middle of August, 

 because, if we should have a cold au- 

 tumn they would not fill the pots with 

 strong healthy roots.

MILDEW, whether on the stems of 

 the wheat, or on the leaves of the chry- 

 santhemum, pea, rose, or peach, ap- 

 pears in the form of minute fungi, the 

 roots of which penetrate the pores of 

 the epidermis, rob the plant of its 

 juices, and interrupt its respiration. 

 There seems to be every reason to be- 

 lieve that the fungus is communicated 

 to the plants from the soil. Every 

 specimen of these fungi emits annually 



myriads of rnftmte seeds, and these are 

 wafted over the soil by every wind, ve- 

 getating and reproducing seed, if they 

 have happened to be deposited in a 

 favourable place, or remaining until 

 the following spring without germinat- 

 ing. These fungi have the power of 

 spreading also by stooling or throwing 

 out offsets. They are never absent 

 from a soil, and at some period of its 

 growth are annually to be found upon 

 the plants liable to their inroads. They 

 are more observed in cold, damp, 

 muggy seasons, because such seasons 

 are peculiarly favourable to the growth 

 of all fungi. The best of all cures is 

 afforded by the application of flowers 

 of sulphur in some form to the parts 

 affected, either by dusting the sulphur 

 over the parts affected, or a sulphur 

 paint, for which a recipe is given at 

 page 260; merely clay, water, and 

 ilowers of sulphur, however, are suffi- 

 cient, and not so injurious to leaves. 

 Vre'do ro'sce, Pucci'nia ro'sce, and Ola- 

 dospo'rium herb a? rum, are the mildew 

 fungi of the rose-tree ; Oi'dium crysi- 

 phoi'des of the peach-tree ; Oi'dium 

 Tucke'ri of the vine ; Glceospo'rium con- 

 centri'cum of the cabbage ; and Ery'siphc 

 commu'nis of the pea. Of course there 

 are many others. 



The most important point for sub- 

 duing the mildew fungus, is to apply 

 the sulphur immediately it appears. 

 To prevent its occurrence, nothing is 

 so effectual as keeping the roots and 

 the leaves equally active by a due 

 amount of warmth and moisture.
