The report of the special commission ap- 

 pointed by the Dutch government to discuss the 

 scheme of draining the Zuyder Zee has been 

 submitted. According to the Raihvay Review it 

 states that such an undertaking is quite possi- 

 ble. The work would take 31 years for com- 

 pletion, and every year 10,000 hectares of land 

 would be restored to cultivation. A dike 30 

 miles in length would have to be constructed, 

 extending from the extreme end of South Hol- 

 land to the eastern coast of Friesland. The build- 

 ing of this dike, 35 meters wide at the base and 

 six meters high, will take nine years. The 

 total cost of the work is estimated at £26,000,- 

 000, which includes the amount to be paid in 

 indemnities to the fishermen of the Zuyder Zee. 

 The total value of the land thus reclaimed from 

 the ocean is estimated at £27,000,000, so that 

 the Dutch treasury net a profit of £1,000,000, 

 without reckoning the substantial gain to the
