rate of tillering in the former to a less extent. A tendency was noted for high 

 tillering mother plants to produce a larger proportion of plants with a larger 

 number of tillers than the average, but the inheritance of tillering as indicated 

 by the performance of individual plants was not marked. 



Increased yields per spike accompanied an increase in the number of tillers 

 per plant up to 4 or 5 tillers, beyond which the yield was more or less uniform. 

 Low tillering plants of a variety produced smaller yields per spike and grain 

 of poor quality. Within a variety under similar conditions of planting the 

 quality of grain was correlated to some extent with the number of tillers per 

 plant. Varieties with coarse, stiff straw did not tiller so freely as those with 

 finer, more pliable straw. Depth of planting did not appear to affect materially 

 the number of tillers per plant. The improved quality of grain used for seed, 

 as indicated by size, plumpness, and weight, favored a higher rate of tillering. 



Regulations and instructions relating' to the labelling, inspection, and 

 analysis of seeds in New Jersey, J. P. Heltae {New Jersey Stas. Circ. 66 

 (1917), pp. S-10). — This outlines the rules and regulations promulgated by the

The manuring of market garden crops, with special reference to the use 

 of fertilizers, F. T. Shtjtt and B. L. Emslie (Canada Expt. Farms Bui. 52, 

 2. ser. (1917), pp. 36). — This bulletin deals briefly with some of the important 

 features of market gardening in Canada, with special reference to the selection 

 and use of fertilizers and fertilizing materials. Data on fertilizer experiments 

 with vegetables conducted in 1915 are appended. The results as a whole indi- 

 cate the economic advantage of a medium application of manure with suitable 

 commercial fertilizers as compared with the use of a large quantity of manure 

 alone. 



Possibilities of the fall vegetable garden, O. E. Dttest (Illinois Sta. Circ. 

 BOO (1917), pp. 8, fig. 1). — This circular deals with vegetables which can be 

 made available for fall use. CJonsideration is given to vegetables planted in 

 early spring and which are capable of surviving hot dry weather, vegetables 

 planted in late spring and early summer, and quick maturing vegetables 

 planted in late summer or early fall especially for fall use. 



Variety tests of potatoes, tomatoes, cabbage, and other vegetables, T. H.

 tains the hitherto unpublished notes and records of vegetables that have been 

 tested at the station during the past ten years.
