 The scheme of cropping for 1923 is as follows : — 



The ration per cow will be, from mid-October to the end of 

 May — 601b. green fodder and 151b. dry fodder (81b. mixtures and 

 71b. hay) . For the rest (June to mid-October) the cows will be 

 at grass, aided by forage crops. 



On the best pasture the cows are being grazed in rotation, the 

 aim being to secure the advantages of the continental practice of 

 tethering without its disadvantages. They receive also one feed 

 per day of chaffed rye and peas. 



LOANS OF LANTP:RN slides to LECTURERS. 



Lecturers on agricultural science can obtain from the Rotham- 

 sted Experimental Station the loan of certain lantern slides free of 

 charge, but on condition that all breakages are replaced. 



CO-OPERATION WITH SCHOOLS AND OTHER AGENCIES 



Three of the departments have found it advantageous to invite 

 the co-operation of public and elementary schools for the collection 

 of data, and it is satisfactory to record that the scheme has proved 

 successful. In the first instance, a committee of the Science 

 Masters' Association, under the chairmanship of O. H. Latter, 

 Esq., M.A. (Charterhouse School), was formed, and a number of 

 public schools co-operated. Relations have now been secured with 

 practically every type of educational institution : public schools, 

 secondary schools, training colleges, and rural schools. Certain 

 observations on weeds carried out by training colleges and country 

 school teachers are proving very useful to the Botanical Depart- 

 ment ; other observations of times of flowering, ripening, etc., are 

 of assistance to the Statistical Department in estimating the effect 

 of season on plant growth.
