ENGLISH GRASS EXPERIMENTS 309 



stone rocks of the Mountain Limestone and the Millstone Grit, and 

 other light soils poor in lime, may be effectually improved by the 

 foregoing treatment, with the addition of, say 2 cwt. of muriate of 

 potash to the slag. For the after treatment of these pastures, and 

 for the general treatment of those in better condition, the same 

 manuring as is outlined for the manuring of old land hay may be 

 followed. Dung, however, is not likely to give as good results for 

 pasture as for hay-making purposes, but it should be noted that 

 dung greatly assists the formation of a sward on thin pasture soils 

 which have been recently laid down. When limestone is the under- 

 lying rock, superphosphate may be more useful than slag, while the 

 feeding of cake will also be useful. The same remarks apply to 

 lime as have been made in connection with old land hay." 



Example of Pasture Improvement in England. In 

 Bulletin No. 8 of the County of Northumberland Edu- 

 cation Committee, Prof. Douglas A. Gilchrist presents 

 the results of pasture experiments running from 1897 

 to. 1905. This collection of data is so strikingly useful 

 in giving a basis on which to work and something from 

 which to plan work of our own, that I present the greater 

 part of it. I regret that the sheep pastured were all 

 wethers, since it may be that ewes with lambs would 

 have shown greater gains. It is significant, however, 

 that one may expect from pasturing wethers during the 

 summer season (the reader will find by table the vary- 

 ing lengths) gains of from nothing (on unfed pasture) 

 to 152 pounds per acre where the pasture has had liberal 

 treatment which in this instance meant cake (cotton- 

 seed) fed on the grass and in one instance 163 pounds 

 where basic slag was used. While these results seem 

 somewhat small yet it must be conceded that here a gain 

 of 100 pounds per acre from pasturing would net at least 

 $5 more rental for the land, and with our fresher soils
