 Compt. Rend. Acad. Sci. Paris 170: 285 287. L920. -The anatomical modifications in the re- 

 gion of the grafl arc held fco be due primarily to the cushion (bourlrelel I develop) d at I he union 

 of stock and scion. This causes a diversion of conductive processes, altering the distribution 

 of materials. Some substances are found to pass, others will nol pass, and other substances 

 arc chemically changed before passage. Thus the biologic nature of the stork and scion is 

 considered as changed. This tissue is also concerned in the development of all excrescences 

 at this level, including roots of the scion, shoots of the stock and complex ti to graft 

 hybrids or chimeras when such occur. — C. II . and W. K. Farr.

 which is never fasciated nor branches dichotomously was grafted to a stock of Goncalo Pires, 

 another variety of the same species, which has fasciation and dichotomy as a permanent char- 

 acteristic. Shoots of the scion developed later were found to be fasciated and dichotomous 

 like those of the stock. — C. H. and W. K. Farr.

 1920. — Scions were taken in 1895, at the Missouri station from two bearing Ben Davis trees 

 and from these other trees were propagated. One of the Ben Davis trees, from which the sci- 

 ons were taken, had been a heavy and regular producer of high grade fruit, while the other had 

 been a light producer of fruit inferior in size and color. The crops resulting from these two 

 groups of propagated trees were measured accurately. The author states, "The results of 

 this particular experiment may be summarized by stating that the trees propagated from the 

 poor parent were equal to those propagated from the good parent in productiveness, regularity 

 of bearing and grade of fruit." — Another bud selection experiment was made at the Missouri 

 station with strawberries. Runners were taken from the six most productive individuals in 

 the station's plot of a standard variety. Records of yields were kept, and each year for ten 

 years, plants from the highest yielding and low yielding plants w-ere selected and fruited. 

 Nothing was gained or lost by selection. — In 1913, at the Oregon station, plus and minus selec- 

 tions were made of four varieties of strawberries. Daughter plants w r ere fruited in 1915, and 

 for three succeeding generations, with the same results as found at the Missouri station. The 

 low yielding Wilson mother plant was a poor plant maker. This characteristic was exhibited 

 by each group of daughter plants throughout their life. At the same time as the above study, 

 selections were made from productive and barren daughter plants of two station seedlings. 

 The resulting records showed that the high yielding selections remained at least above the 

 normal, while the selections from the barren plants continued to be nearly barren. In this 

 case, a strain of strawberries, inferior to the normal was isolated. The author states, "From
