which otherwise would involve inconvenient and expensive 

 journeys to neighbouring towns, or which he could not do 

 at all owing to the delay involved in reaching the other 

 parties concerned. When his work is over he and his family 

 can talk to their friends and neighbours, and can even 

 arrange social meetings which would otherwise be impossible. 

 In many other ways, too numerous to mention, the telephone 

 helps him to overcome the chief drawbacks of country life, 

 and enables him to do business on as good a footing as if he 

 lived in a town. 



If you would like to have a telephone service of this kind 

 in your district, please write to the Secretary, General Post 

 Office, London. Before you do so try to interest your neigh- 

 bours in the scheme, and find out how many are willing to 

 join at the rate of £3 per year for unlimited calls on their 

 own exchange, and with the power of talking to other towns 

 at the rate of id., 2d., 3d. per conversation, according to the 

 distance for towns within 25 miles and at the rate of 6d. for 

 towns within 50 miles. 



To make the scheme practicable a minimum of five sub- 

 scribers is required, with an average of three subscribers per 

 mile of route from the telephone exchange. Full particulars 

 will be sent to you by post, and, if there is any prospect of a 

 successful scheme, a representative will come to discuss the 

 matter with you personally. 



SUMMARY OF AGRICULTURAL EXPERIMENTS. 



Calcium Cyanamide and Nitrate of Lime (Roy. Agric. Coll., Scientific 

 Bulletin, No. 2, 19 10). — Four nitrogenous manures were compared on 

 oats. The plots were each j 1 ^ acre, and each manure was used on 

 two different plots. A dressing of mineral superphosphate, at the rate j 

 of 3 cwt. per acre, was given to all the plots except the unmanured, 

 sulphate of ammonia was used at the rate of 1 cwt. per acre, and the 

 other manures in quantities containing the same amount of nitrogen 

 as 1 cwt. sulphate of ammonia, viz., nitrate of soda, 147 lb. ; nitrate 

 of lime, 176 lb., calcium cyanamide, 140 lb. The results per acre, 

 taking the average of the two plots in each case, were : —
