home. Fresh green manure does not suit Trefoil, but a top 

 dressing of a good compost or of vegetable ash generally brings 

 a full crop. AU manures containing potash and phosphoric acid 

 have a magical effect on its growth. 



Sheep injure it less than they do Eed Clover, and it is 

 supposed to impart colour and good ilavour to butter. 



Trefoil is rarely sown alone, but frequently in company 

 with White Clover, and it is important that the latter should 

 predominate or the former may take entire possession of the 

 land. Foxtail, Sweet Vernal, and Smooth-stalked Meadow Grass 

 combine well with Trefoil in affording early and valuable 

 herbage. 



The botanical description and chemical analysis are given on

Lotus corniculatus {Birdsfoot Trefoil). — This plant is 

 strictly perennial, and attains maturity in the second year after 

 sowing. It often fills up the bottom of a pasture when other 

 sorts are deficient, and it will do this on land which is clover-sick. 

 Birdsfoot Trefoil is useful for all soils, and is remarkable for its 

 endurance of drought, however extreme. There are high exposed 

 thin soils where it is more productive than any other clover, and 

 it seems to augment the total of the crop without detriment to 

 the taller upright-growing varieties. Therefore, if expense need 

 not be considered, seed in limited quantity should certainly be 

 sown. Unfortunately such soils do not often warrant the outlay 

 for this clover, the price of which is almost prohibitory. 



Achillea Millefolium {Yarrow, or Milfoil), although 

 neither a grass nor a clover, is such an ever-present constituent of 

 dry pastures that it naturally comes up for consideration among 

 agricultural grasses. It is strictly perennial, and multiplies itself 

 by root-growth. The leaves are dense and elegantly fimbriated. 

 The flowering time is after midsummer. This plant appears
