Hitherto no works of the kind have been erected in Britain, 

 though the West of Scotland would be suitable for this industry. 



The British market is now supplied with cyanamide by a large 

 factory, working with the Frank & Caro process, situated on the 

 Hardanger Fjord, Norway, and belonging to an English company. 

 In the same neighbourhood nitrate of lime is also made. 



The following table shows analyses of some samples analysed 

 in the author's laboratory : 



In Scotland several pot and field experiments have been made 

 with these manures, and the general results seem to indicate that 

 nitrate of lime is an even more active and valuable manure, weight 

 for weight of nitrogen, than nitrate of soda.

 and Nitrate of Lime. The Journal of the Board of Agricul-

"In view of the importance of the two new fertilisers containing 

 nitrogen extracted from the atmosphere, calcium cyanamide or ni- 

 trolime and nitrate of lime both of which are now becoming re- 

 gular articles of commerce, the results of a comparative trial o f 

 these manures against sulphate of ammonia and nitrate of soda, 

 made at Rothamsted in 1909, may not be without interest. The 

 experimental plots were situated in Little Hoos field, the soil of 

 which, as of the other Rothamsted fields, is a heavy clay loam 

 containing between i and 2 per cent, of carbonate of lime in the
