Crops for Sewage Irrigation 411 



yields are desired. On the Craigentinny Meadows, most of the 

 grasses are the native forms, which soon crowd out the Rye 

 Grass if it is not reseeded. 



Both oats and wheat are extensively grown on sewage 

 land, but in these cases the land is usually only irrigated dur- 

 ing the winter. Potatoes, turnips and mangels, as well as 

 cabbage and cauliflower, are also grown. 



At Croyden and Preston, potatoes are grown on a large 

 scale on winter irrigated land and the crop sold at auction 

 when mature at $60 to $75 per acre, the purchaser digging the 

 potatoes. Fig. 129 shows a crop of early potatoes grown at 

 Croyden which sold in July for 15 per acre, and Fig. 130 is 

 a view of the cement ditch in which the water is brought to 

 the fields from the city. When summer irrigation of potatoes 

 is practiced at Croyden, the superintendent stated that he pre- 

 ferred to use the water only after it had drained from another 

 field. He also stated that he thought the sewage water tended 

 to intensify the scab. 



At Nottingham, where much wheat is raised, this is grown 

 on winter irrigated land, but cabbage, turnips and mangels are 

 irrigated in the summer as well as winter. The cabbages 

 raised here -are the large stock varieties, planted in rows 4 

 feet apart with the plants 3 feet apart in the row, and 

 enormous yields are secured of the vegetables named and fed 

 to a herd of from 800 to 1,000 cows. 



At Gennevilliers, nearly all varieties of garden truck were 

 being raised with great success, and there were orchards of 

 pears, prunes and apples, and vineyards of grapes, heavily 

 loaded with fruit in August of 1895. So, too, at Berlin, 

 mangels, turnips, celery, onions, parsnips, beans, cabbage and 

 cauliflower were raised on their sewage farms. 



While the general practice in Europe seems to be to favor 

 summer irrigation of grass, and winter irrigation for small 

 grains and cultivated crops generally, it appears clear that 

 there are few if any crops to which sewage may not be applied 

 with great advantage if only rational practice is followed. 



It will be readily understood that where fertilization is the
