.1 difBcult matter to properly enrich sufficient ground for the crop of 

 succotash. A small area only is necessary, say from one to three acres, 

 to tide the average dairyman over from clover to corn on a failing 

 pasturage. Manure cannot well be used to better advantage than on this 

 area. We have found that the manure for this crop should not be buried 

 too deep, for the crop should be induced to start and grow quickly; it 

 is short lived. Our best results have come from spreading a good coat- 

 ing of heavy manure (not strawy) on the land after plowing and before 

 fitting for seeding; this manure is not allowed to lie on the surface 

 of the ground but is worked into and incorporated with the top two or 

 three inches of soil by means of the disk and harrow. This plan almost 

 insures a quick and vigorous start of the small seeds such as clover and 

 rape. After the seed bed has been thoroughly prepared, sow a good seed- 

 ing of rape and clover mixed, broadcasting it and then follow with the 

 seed drill burying the mixture of corn, peas and oats at the proper 

 depth; the drill will cover the small seeds previously sown on the sur- 

 face. In general the grain mixture should be sown at the rate of about 

 two bushels per acre. 



SUCCOTASH JIAY VARY IN COMPOSITION. 



Though the seeds of the various species of the mixture may be sown 

 in definite proportions, at each seeding of the season, still, we should 

 expect the relative numbers of plants of each to vary somewhat with 

 peculiarities of climatic conditions, and the same results must be ex- 

 pected to follow as regards the relative development of the different 

 sorts. This is illustrated quite markely by a comparison of illustra- 

 tions Kos. 3 and 4. 



RAINFALL. 



In this publication attention is directed to the amount of rainfall dur- 

 ing the growing periods of the several crops produced. This is done be- 

 cause of the fact that the seasons of 1903 and lOO.o were extremely 

 unusual in their large preci])itation. Up to a certain degree the rainfall 

 may effect yields favorably and beyond that may become injurious. For 

 purposes of comparison we give the average rainfall for four of the sum- 

 mer months during the five years preceding 1003. as follows: May 3.39 

 in., June 3.8 in., July 3.91 in., and August 1.93 in. 



SUCCOTASH. 



Report of first year, 1902. 



This consisted of a one third acre lot, one of several of the same area 

 used to produce forage cro|)s for swine. For several years preceding the 

 date given these lots were used for hog runs. One-half of each lot is 

 high land and somewhat heavy, sIo])ing sharjily toward the Cedar river; 

 the lower ends of the lots are quite light and sandy and are usually sub- 

 merged annually by the s])ring fioods. Owing*to the tramj)ling received 

 while wet the soil of these lots had been puddled and was not in the 

 best physicial or mechanical condition to grow good crops the first 

 season.
