Tormentil (Potenlilla Tormentilla Sibth.) is a perennial 

 which occurs in pastures and meadows, especially on 

 poor, dry soils. It is a slightly hairy plant, from 

 6 inches to i foot high, with solitary yellow flowers 

 about \ inch in diameter, bearing usually only four 

 petals. This plant is checked if a plentiful and close 

 bottom herbage is produced. 



Lady's Mantle (Achemilla vulgaris L.) is occasionally 

 too common in moist pastures and meadows, and may 

 occur on any soil, but it is not generally troublesome. 

 Draining and manuring will tend to reduce it. 



Agrimony (Agrimonia Eupatoria L.) is a very common 

 weed of pastures and borders of fields. It is an erect, 

 hairy, leafy plant, without branches, i to 2 feet high, 

 with pinnate, toothed leaves, and shortly stalked, small, 

 yellow flowers placed in a long, spike-like raceme. The 

 plant is perennial, and flowering occurs between June 

 and August. 



Salad Burnet (Polerium Sanguisorba L.) is rejected by 

 stock owing to its hard, woody character when well 

 grown, and is therefore not desirable in excessive quan- 

 tities. At the same time it is eaten in the young state 

 by stock, and its large deep root system makes its 

 presence in small amounts useful, as it opens up the 

 soil to aerial influences, and thus promotes a healthy 

 condition of the root system of other herbage. It is 

 useful on dry calcareous pastures, where difficulty is 

 frequently experienced in ensuring the growth of any- 

 thing better. It is a perennial, flowering in June to 

 August, is about ij feet high, with slender, much 

 branched stems. The leaves are pinnate, the five to ten 

 pairs of leaflets being serrated and stalked. The small 

 reddish-green flowers, without petals, are grouped in 

 dense heads. 



Greater Burnet (Poterium officinale, Hook, f.) is similar
