The unmanured plot gave the very excellent yield of over 

 25 cwt of hay. All the plots, except the kainit alone, gave a higher 

 yield than the unmanured. 



The highest yield was from the plot receiving superphosphate, 

 kainit and nitrate of soda, followed closely by superphosphate 

 kainit and ammonium sulphate, kainit and amm. sulphate, kainit 

 and nitrate of soda, superphosphate and nitrate, and farm-yard 

 manure: all giving over 2 V 4 tons per acre. 



The superphosphate and amm. sulphate, Peruvian guano, and 

 amm. sulphate all gave over 2 tons per acre. Nitrate of soda (alone) 

 gave a slight increase, but its ill effect as compared with amm. sul- 

 phate (alone) was more marked than in former years. Phosphates 

 and potash gave an increase of about l / 2 a ton over the unmanured ; 

 and in the hay there was a much larger proportion of leguminosae 

 than in some of the plots receiving nitrogen in addition. Basic 

 slag and rape meal improved the quality, but had not much action 

 on the quantity of grass. Peruvian guano improved both quality 

 and quantity. 



Buttercups (Ranunculi) were less abundant where the complete 

 mineral manures and where kainit, either with nitrate or with 

 ammonium salts were applied. 



The average yield per acre of all the plots was 37 */ a cwt - of 

 hay, being about 7 x / 2 cwt. more than the average of the whole 

 time of the experiments. 



A preliminary botanical examination of the growth in the field 

 gave 50 species of flowering plants. 



On the unmanured plot and on those receiving kainit alone 

 and nitrate alone, the number of flowering species was about 30. 

 With kainit and superphosphate the number was reduced to 22; 

 and with kainit, superphosphate and nitrate to 16. There were 

 no buttercups on this last plot, on which 13 of the species were 

 grasses and leguminosae. Cocksfoot (Dactylis glomeratd) formed a 

 higher percentage than on any other plot; and the miscellaneous 

 herbage was represented only by Potentilla repens, Cerastium triviale, 

 and Galium vcrum. 



On the unmanured plot Lathyrus pratensis was by far the most 

 abundant of the leguminosae ; here the ratio of the weight of grasses 

 to leguminosae was very nearly 9:1, and of the latter nine tenths 

 was Lathyrus,
