combination of all. He suggests that we look into the inside of the tree rather than into the 

 soil or other external factors. In other words, we should attempt to diagnose the trouble, 

 and then make an attempt to discover a treatment for it. This means a need of men trained 

 in physiology and chemistry, and of considerable laboratory work under more controlled 

 conditions. It is suggested that, to start with, we should eliminate the error introduced by 

 miscellaneous stocks and scions; and the writer suggests that buds or scions from a single 

 parent tree should be worked upon root stocks, developed by cuttings or other asexual propa- 

 gation from a single parent plant. It is suggested that in place of a "fertilizer project" we 

 should have a "nutrition project," and that most of the old type of fertilizer experiments 

 should be carried on as demonstrations by extension workers.— J?. C. Anchter.

953. Anthony, R. D. Methods of interpreting results in orchard fertilizer experiments. 

 Proc. Amer. Soc. Hortic. Sci. 16: 113-117 (1919) 1920.— It is shown that many of our fertilizer 

 experiments were planned and laid out before there was much published information on the 

 subject. As a result, many errors were made in planning the experiments and in interpreting 

 the results. Some points which should be noted and studied are the following: (a) Weighted 

 results are often given without giving the methods of deriving these or the original values. 

 (b) If four-year overlapping averages were used it would tend to smooth the yield curves 

 and make it easier to compare the records of different plots, (c) the cultural treatment of the 

 orchard is not always given, (d) A s'trip of sod in the tree rows of cultivated orchards should 

 be noted, (e) The contour of the land is not always given, (f) Not only should checks be 

 repeated, but often the different treatments, (g) Soil variations should be recorded, (h) 

 Cross-feeding should be prevented or acknowledged, (i) The performance of a single ele- 

 ment cannot always be detertained by subtracting the performance of a two-element plot 

 from a three-element one. (j) There is a big variation in individual-tree performance. 

 (k) We must not make too wide an application of a single fertilizer experiment even in the 

 same country. (I) To find out how much variation there is between plots, without any fer-
