high, June 11; it measured twenty-five inches, June 19. 

 The oats l)egan to head out, June 24, and the vetch to 

 bloom, June 25 ; the entire growth was, on an average, 

 thirty inches high, June 28, when the cutting for the daily 

 feed began. The last of the crop was cut July 17 ; it had 

 reached a height of forty inches. The average moisture of 

 the green fodder for the entire period was 78.2(i per cent., 

 which makes the solid vegetable matter 21.74 per cent. 

 The entire yield of the green crop was 5,440 pounds, 

 or 8^ tons per acre. This result is not as good, as far as 

 quantity is concerned, as that secured during the preceding 

 year, when a mixture of 25 pounds of vetch and 50 pounds 

 of oats were used as seed ; the rate of yield per acre in that 

 year was 9^ tons of green fodder. The area occupied by 

 vetch and oats was not large enough to answer fully our 

 purpose, to cover the time until the cow-pea is fit to be 

 used advantageously. We shall hereafter double the area, 

 and seed one-half down, as we did before, towards the 

 close of April, and the other half from two to three weeks 

 later. 



Serradella. — The young plants w^ere out May 1(3. The 

 crop was kept clean with the cultivator and hoe. It is a 

 peculiar feature of this crop, that its growth is very slow 

 until it liegins to bloom, when it rapidly branches out, and 

 causes finally a compact, bulky green mass, filling out com- 

 pletely the three feet of space l)etween the rows. The seed 

 was sown, May 8; the plants ap})eared above ground, May 

 16; they were but one inch high, June 11; two inches, 

 June 19 ; two and one-half inches, June 2Q ; and four 

 inches, July 3 ; began blooming, July 6 ; ten inches high, 

 July 24; began spreading, July 31; reached thirteen 

 inches in height, August 21. The first feed was cut 

 September 11, when it formed a dense mass, several 

 feet wide ; the last feed was cut September 27. The 

 green crop harvested amounted to 8,350 pounds, or 

 13| tons per acre. The average moisture was 83. H5 

 per cent., and the solid vegetable matter 16.35 per 

 cent. 



Southern Cow-pea. — The young plants were seen six 

 days after planting. The crop was cultivated and kept
