Solving in the open ground from the 

 end of April to the beginning of July 

 will produce a sure succession of blooms 

 through the year. If allowed to seed 

 and the soil suits it, mignonette will

 treated in a similar manner, and the 

 next year it may be allowed to bloom, 

 which, with care, it will continue to do 

 for several years." — Gard. Chron.

MILDEW, whether on the stems of 

 the wheat, or on the leaves of the 

 chrysanthemum, pea, rose^ or peach, 

 appears 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 me 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 minute seeds, and these are 

 wafted over the soil by every wind, 

 vegetating and reproducing seed, if 

 they have happened to be deposited in a 

 favourable place, or remaining until the 

 following spring without germinating. 

 These fungi have the power of spread- 

 ing also by stooling or throwing out off- 

 sets. They are never absent from a 

 soil, afld 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 pe- 

 culiarly favourable to the growth of all 

 fungi. The best of all cures is a 

 weak solution of common salt and wa-
