EXPERIMENT ON BARLEY AFTER TURNIPS. 



18G4. 

 The field on which this experiment was made, had produced a 

 fair crop of Swedes the year previous, which had been carted off 

 to the cattle. Of course, as in the other experiment of this 

 year, the excessive drought was in favour of the Sewage, and 

 against the Nitrate of Soda. The plots were half an acre each.

In 1864, I marked out four half-acre plots in a turnip field 

 of nine acres, for two different quantities of Sewage, and two 

 different manures, leaving a fifth half acre unmanured, for com- 

 parison. Unfortunately, the excessive drought or heat of the 

 season, brought us a visitation of the Grub to such an extent, 

 that after having arrived at a good size, the whole field was 

 completely destroyed. In 1859, however, I tried the effect of 

 Sewage on green crop, but not with measured quantity. The 

 crop was Mangold Wurtzel, and had arrived at the size of an 

 orange, when it began to give way, apparently from heat and 

 drought. I turned a stream of Sewage down the drills, and al- 

 lowed it to run freely for several days. The result was to in- 

 vigorate the plant, and secure me a crop of 26-^ tons to the acre. 



As some guide to the value, positive and comparative, ot 

 Sewaged grass, 1 will now give a statement of the quantity of 

 grass consumed in 24 weeks by 20 of my milk cows, ten of 

 which were fed on natural meadow grass, which had been well 

 watered with Town Sewage, five on the same description of 

 grass, but without Sewage, and five more on Italian rye-grass 

 also unsewaged. I also give the quantity of milk produced from 

 each lot.
