than twenty-four hours after the cake feeding begins, and 

 continues to do so for several days after it has been dropped. 



4. The reactions vary in intensity in individual cows, but 

 do not in any case much exceed those given by i per cent, 

 of cottonseed oil mixed with butter. The presumption is, 

 therefore, that in butter made in the ordinary way from the 

 mixed milks of several cows the reaction would as a rule be 

 less than that due to the presence of i per cent, of the oil. 

 and experiment shows that this is actually the case. 



5. As feeding with cottonseed oilcake gives butter affording 

 analytical data tending to differ from, rather than to approach 

 to, those given by margarine, it appears to be possible in 

 most cases to differentiate between the cottonseed oil reaction 

 due to feeding on cottonseed oilcake and that produced by 

 any considerable admixture of margarine containing cotton- 

 seed oil with butter. 



6. The butter from the milk of cows fed on sesame oilcake 

 gives no sesame oil reaction, even after more than two 

 months continuous feeding up to as large a quantity as the 

 cows will take. 



Similar results have been obtained by other observers 

 abroad. 



Experiments with Basic Slag on Clay Land. 



The last number of the Journal of the Bath and West of 

 England Society contains an interesting abridged report by 

 the Botanical Visitor of the Society upon the results of some 

 experimental trials with basic slag upon poor clay land 

 These experiments were carried out on a number of sites 

 upon the Digby Estate, in the neighbourhood of Sherborne, 

 Dorset. The nature of the soil experimented upon in almost 

 every case was such as would come under the denomination 

 of poor, cold clay ; and it was upon some of the poorest of 

 these examples that the most marked results were pro- 

 duced. The manure was sown in March, 1895, upon half-acre 

 plots, at the rate of S cw^t. per acre. The severe drought of 

 the summer of 1895 prevented any results being observed 

 during that year, and as the season of 1896 also proved to be
