THE AMAKYLLIDE^. 
ARTICLE IV.— YEAST AS MANURE. 
Dr. Thomson in his Annals of Philosophy (vol. 16,) mentioned 
having seen a cimoiis experiment made in the early part of the sum- 
mer of 1820, hy Mr. Phillip Taylor, of Bromley, the effects of which 
he witnessed in the month of June of that year. Mr. Taylor put 
upon a grass field, a quantity of common porter yeast, in order to see 
what effect it would have as manure. In the month of June when 
Dr. Thompson saw the field, the effect of the yeast was very remark- 
able. That portion of the field which had been manured with it, was 
of a much darker colour, and the grass on it was much longer than 
on the remaining portion of the field. Thus, adds Dr. Thomson, there 
cannot be a doubt, that porter yeast, and every kind of yeast, may 
be employed as a very eflScacious manure, and it is easy to imagine 
various cases in which yeast might be applied as a manure with con- 
siderable advantage. J. T.

All the species of this genus thrive in a light sandy soil, and 
force well either in pots of soil or glasses of water. They are well 
known inhabitants of the flower borders^ and constitute one of its 
greatest ornaments. INIany of the more choice kinds are gTown in 
beds composed of equal parts of strong rich loam, leaf-mould and 
rotten dung, with a small portion of sand. Li November the bulbs 
are planted about three inches deep, and seven inches apart. The 
roots should be taken up every three years and replanted, separating 
the offsets. The season for doing this either in borders or beds, is 
as soon as the tops have died down, which generally happens in July ; 
choose a fine day for the pui-^iose, spread them on a mat in the sun 
to dry for a few days, after which remove them to a cold shed, and
