a conveyor of this nature installed for a German factory of chemi- 

 <3al products by Ad. Bleichert & Co. Sometimes, as will be seen 

 in Fig. 67, the cargo discharged from ships is simply disgorged by 

 tilting-bins or sUngs into fixed or rolling hoppers or into rolling 

 stock, or sometimes, on the other hand, these automatic tran- 

 shipping installations are continued by automatic conveyors like 

 those described above. The attention of those working phosphate 

 deposits is drawn to the rope system adopted by the G''' Centrate 

 des Phosphates d Paris for working its deposits of Bordj E'Dir. 



There will be seen in Fig. 69 a considerable development of 

 these rope railways which collect the phosphate into the great 

 warehousing hoppers at the railway station of El Anasser Galbois, 

 Algeria. Local considerations, the price of labour, the greater or 

 less tonnage to be discharged and handled, the regular or inter- 

 mittent manner in which these transhipments or shiftings occur, 

 can alone afford, in each case, the necessary data to solve the problem 

 in the most satisfactory manner in the interests of the manufacturer. 

 The best course for manufacturers who occupy themselves with 

 these questions more and more is to submit the problem to the 

 study of specialists trained by constant practice.
