■disease by Mr. Scgar, it is conceived to be of a 

 very sharp corrosive nature, and by its acrimony 

 to hinder the circulation of the nutritious sap ; 

 in consequence of which the leaves begin to 

 fade, and the blossoms and fruit to be greatly 

 injured. 



The author first mentioned conceives the best 

 ■method of removing it to be by admitting more 

 light and air, by proper thinning or pruning 

 so as to restore the natural vigour of the plants. 



Mr. Forsyth has observed that, " contrary 

 to the common opinion, trees are more liable to 

 mildew on south and west walls, than on an 

 east wall ; and has frccjuently removed such 

 trees from a south or west wall, to a north 

 •or east wall, where they have perfectly re- 

 covered. 



He advises " whenever danger is appre- 

 hended, to wash or sprinkle the trees well 

 with urine and lime-water mixed ; and when 

 the young and tender shoots are much infected, 

 to wash them well with a woollen cloth 

 dipped in the following mixture, so as to clear 

 them of all the glutinous matter, that their re- 

 spiration and perspiration may not be ob- 

 structed. 



" Take of tobacco one pound, sulphur two 

 pounds, unslaked lime one peck, and about a 

 pound of elder-buds ; pour on them ten gallons 

 of boiling water ; cover it close and let it stand 

 till cold ; then add as much cold water as will 

 fill a hogshead. It should stand two or three 

 days to settle, when the scum may be taken oft", 

 and it is fit for use. 



"There is a sweet saccharine substance found 

 on the leaves of certain trees, which is generally 

 but erroneously supposed to fall from heaven 

 like dew. It is known by the title of Honey- 

 dew. There are supposed to be two kinds of 

 it, one of which" Mr. Forsyth says "transpires 

 from the leaves of the trees where it is found ; 

 and the other is the excrement of a small insect 

 called a Vine-fretter, a species of the Aphis. 

 Bees and ants are very fond of both these 

 kinds of honey-dew." As this exudation, "by 

 its viscous quality," closes up the pores and 

 stcJps the perspiration of trees, it iTiUstof course," 

 he thinks, " be very hurtful to them." 



It is a vegetable disease, which should, in his 

 opinion, be treated in the same manner as the 

 mildew, by washing at the same times. 



MIMOSA, a genus containing plants of the 

 shrubby and under shrubby kind. 



It belongs to the class and order Polygamia 

 Moneecia and ranks in the natural order of Lo- 

 mevtacece. 



'I he characters are : that the calyx is a one- 

 kaffcd perianthium, five-toothed, very small :

 five-cleft, small : the stamina have capillary, 

 very long filaments : anthers incumbent : the 

 pistillum is aii oblong germ : style filiform, 

 shorter than the stamens: stigma truncated: 

 the pericarpium is a long legume, with several 

 transverse partitions: the seeds many, roundish, 

 of various forms.

 The first, when cultivated in the garden, has 



great resemblance to the seventh sort ; but the 

 stalks never grow so erect, the wings of the 

 leaves are longer, and stand more horizontal : 

 the heads of flowers are much larger, the 

 stamens are longer, and the flowers on the 

 under side of the spike which have no stamens 

 are double ; the pods also are shorter, and much 

 broader than those of that sort. 



It is annual ; the stems round, herbaceous, 

 smooth, procumbent, rooting at all the joints : 

 the leaves three-paired or four-paired, contract- 

 ing with the least touch : from the axils of 

 these spring erect peduncles, four or five inches 

 high, with scales the whole length, sustaining 

 handsome, yellow, almost globular heads, the 

 same size with those of red clover: the flowers 

 difterent in shape, nature and use; those in the 

 middle truly five-petalled, in small five-cleft 

 calyxes, with many long stamens; but those in 

 the circuit, instead of stamens have oblong, 

 beautiful, golden leaflets, much wider and hand- 

 somer than the true petals, which are small
