Tlio cutting on this field was begun May 6, ISOO, a total of 

 foil V tivo cuttings being made in each row. The amount taken 

 from each at each cutting was weighed separately and a record 

 kt'i.t of the weighings. In this way we obtained the yielding 

 capacity of each row. It was found that the rust had redut-cd 

 the vitality of the Held until it was yielding very lightly. The 

 last cutting was made July 1. after which the field was plowed 

 down and allowed to grow. On July 28, the spraying was coni- 

 menci'd. every other row being sprayed. The odd numbers were 

 spiayed, the even numbers being left as checks, as shown in the 

 following chart:
