ductive and nutrient properties of Yarrow are inferior to those of other plants equally 
adapted to light soils, Mr. Sinclair considers it an indispensable ingredient of the most 
fattening and healthy pastures, in which he suspects it may not be destitute of sanative 
effects. We are assured by W. P. Taunton, Esq. in Hort. Gram, that the prevalence of 
this plant indicates a siliceous soil. It is sometimes used in the north of Europe as a sub¬ 
stitute for hops, and also supposed to increase the inebriating quality of malt liquor. E.)
