Pasture Problems 



as a pasture. In the other case (see Table IV) hay was taken constantly 

 for six years. 



Table III. To show mixture used in lbs. per acre and percentage 

 frequency of the herbage on a pasture at 650'-700' in its fifth, sixth 

 and seventh years respectively. 



* Lolium Italicum, 5 lbs. ; Festuca duriuscula, 2-5 lbs. ; F. elatior, F. pratensis and 

 Poa pratensis, 0-25 lb. each. 



f The figures for this grass are unusually high ; and arc probably due to the intro- 

 duction of the seed by wind from a piece of waste ground near the field on which the 

 grass was very plentiful. 



% Trifolium pratense, 2 lbs. ; T. pratense perenne, 2 lbs. ; T. hybridum, 1-5 lbs. ; 

 Anthyllis Vulneraria, 0-25 lb. 



A number of other analyses are available of fields of various ages 

 at these elevations sown with known mixtures. In order, however, 

 not to unnecessarily burden this paper with tables, the chief results 

 obtained can be briefly stated as follows : 



Lolium Italicum. 4 and 5 lbs. sown has not given traces of the 

 plant after four years. 



Dactylis glomerata. On clay drift at 600', 3 lbs. per acre gave 5 % 

 of herbage after four years; and 8 lbs. per acre gave 11 % of herbage. 

 After eleven years the herbage from 6 lbs. was only 1-5 %. 



Phleum pratense. On the average of two sets of analyses equal 

 sowings of this grass on soil ex shale and ex drift (= clay) gave about 

 the same percentage of herbage in both cases at four years.
