UTILIZATION, MARKET AND TECHNOLOGY. 



An important and comprehensive contribu- 



Nezv tion on charcoal manufacture, based on ex- 



Knowledge periments under practical conditions is fur- 



on nished by Denz, who for 20 years has had 



Charcoal charge of charcoal works in Hungary and 



Manufacture. elsewhere. We can here give only the 



results without going into the details of the 



seventeen series of experiments. The author gives also a full 



reference list to works on the subject in German. 



The first experiment was to decide whether Violette's dictum 

 from laboratory experience was correct, that the output of char- 

 coal made with the same temperature is proportional to the dura- 

 tion of the process: slow coaling producing double the amount 

 of rapid coaling; also that the meiler must not go blue. The 

 conclusion from the) two series of experiments are as follows : 



I. The relation, which prevails in the dry distillation of wood, 

 of the duration of the process to quantity does not apply to meilers.
