a spindling growth. The soil in this case was very dark 

 colored and rich in organic matter. 



The plants in soil Xo. (id, bed E, closely resembled in height 

 those in the preceding one. The soil in this case was heavy and 

 compact, bnt contained besides the cow manure considerable 

 pulverized sod. Soil No. 70 in bed A and No. G8 in bed C 

 gave the lowest average growth in height. The latter soil was 

 the same as No. 66, bed E, except that it contained no pul- 

 verized sod. This soil contained the least organic matter of 

 any, was heaA^y and compact, and contained 10 per cent, of 

 clay. When pulverized sod was added, as in No. 66, far better 

 results were obtained. No. 70 was also lacking in organic 

 matter. The heavier, more compact soil developed better leaves 

 and blossoms than the lighter soil. Soil No. 67 produced the 

 best developed plants, while the most slender canes were pro- 

 duced by soil No. 69. 



The largest number of flowers developed on the plants which 

 made the best growth, but the quality was the best in No. 67. 

 The most normally developed plants were grown in soils No. 

 67 and No. GQ, the latter being the only soil to which was 

 added pulverized sod, and the former contained a fairly good 

 supply of well decomposed sod incorporated with the soil when 

 brought from the field into the greenhouse. The addition of 

 sod to some of the other soils would no doubt have given better 

 results. The superior plants produced by soil No. 67 were un- 

 doubtedly due to the large amount of well decomposed sod it 

 contained; in other w'ords, the humus was in a condition to 

 make it more available, whereas in soil No. 66 this was not so, 

 as the sod was applied fresh and was not in the least decom- 

 posed, and in Nos. 70 and 68 there was too little humus. Soil 

 No. 69, obtained from the woods and containing large amounts 

 of decomposed roots, leaves and branches of shrubs and other 

 plants, w^as not suitable for growing stocky plants, although 

 rich in humus. 



The soil in the different beds remained undisturbed during 

 the summer, and a second crop of roses was set out the follow- 

 ing fall. However, before setting out the plants each bed in 

 both sections received a fairly good application of cow manure, 

 this being thoroughly incorporated in the soil. The new plants
