hay, which have been in progress at Shenley since 1898, and at the 

 University Farm since 1901. The same subject was dealt with at three 

 other centres. 



Improvement of Permanent Pasture (Journ. of the Bath and West 

 and Southern Counties Soc, Fifth Series, Vol. II., 1907-8). — A short 

 report is given on the experiments at Stockbridge, in Dorset, and 

 Sampford Courtenay, in Devon, which have been in progress for a number 

 of years. It is observed that the great benefit which these clay lands 

 receive from an application of basic slag is still very apparent, even 

 after six years. Two thing's are noticeable in these experiments, first, the 

 great improvement caused by another lighter dressing of basic slag, and 

 second, the still greater improvement caused by a dressing 1 of good 

 farmyard dung applied one or two years after the basic slag. In the 

 latter case, the grasses seem to participate equally with the clovers in 

 the improvement. 



A report is also given on the results obtained in 1907 in the experiment 

 which has been in progress for eight years at Sevington, near Alresford, 

 Hants. Here, as in the experiments conducted by Cambridge University 

 and by the Highland and Agricultural Society, which are referred to above, 

 the effects of various forms of manuring are tested by feeding sheep 

 upon the plots and comparing the increase obtained. This experiment 

 is not yet concluded, but it may be observed that Plot 3, which received 

 10 cwt. basic slag in 190 1, has given the best financial result over seven 

 years, while Plot 4, which received 5 cwt. basic slag in 190 1 and the 

 same quantity again in 1904, takes the second place. Three other plots 

 gave a greater increase in weight of mutton than Plot 4, but owing to 

 the greater cost of the manures used, the net results were not so good. 



Formation of Permanent Pasture (Univ. Coll. of N. Wales, Bangor, 

 Agric. Dept., Bull. IX., 1906, and VI., 1907). — Experiments with four 

 different mixtures of grass and clover seeds were commenced at nine 

 centres in 1906. The weight of hay obtained in 1907 is givert. 



Manuring of Red Clover for Seed (Beds. C. C Agric. Dept., Rept. 

 on Demonstration Plots, 1907).— An experiment was commenced in 1906 

 to test the effect of manures on red clover, where the first-cut is made 

 into hay, and second-cut left for seed. This was repeated in 1907, but 

 owing to the wet autumn it was impossible to harvest the seed satis- 

 factorily. The weight of the hay crop is given. 



Permanent Red Clover (Harper-Adams Agric. Coll., Field Expts., 

 1907). — An experiment was commenced in 1906 to test a new strain of 

 red clover, viz., Leighton's Inherited Permanent Red. It is claimed for 

 this strain that it is more permanent than ordinary stocks of red clover. 

 Three plots, each two acres in extent, were sown on barley in 1906. 

 Two of these plots were sown with similar mixtures supplied by different 

 seedsmen, but each containing 4 lb. of ordinary red clover; the third 

 plot was sown with the same combination of seeds with 4 lb. per acre 

 of the permanent clover. During the winter a good deal of the ordinary 

 red clover died out, and when growth began in 1907, the plot receiving 

 the permanent clover soon outstripped the other plots, and produced a 

 remarkably heavy crop. The aftermath on this plot was nearly all 

 clover, while that on the other plots contained but little clover, the plants 

 having apparently spent themselves in flowering.
