that black is dominant to white as well as to brown, and the latter is dominant to white. The 

 mode of segregation of these hybrids in F 2 was not yet definitely determined, but it is very 

 probable that in all these hybrids plants with colored seed-coats and those with non-colored 

 ones segregate out in the ratio 15 : 1. Hybrids were also made between races with branch- 

 ing and non-branching habit; between those with glandular and non-glandular capsules; and 

 between those with bilocular and multilocular capsules; in each of these cases the first-named 

 character was found to be dominant to the second, and all these hybrids were found to behave 

 in Fj as typical monohybrids. — S. Ikeno.

 — Refers to article by Van Fleet in Jour. Internat. Gard. Club 3. June, 1919. Author notes 

 that until about 1816 only species in cultivation was Freesia refracta, with a rather tortuous, 

 horizontal flower scape bearing five or more blooms, with bulging corolla lobes of lurid green- 

 ish color, with a pronounced orange blotch. Forty years later florists had succeeded in pro- 

 ducing a greatly improved flower which was nearly pure white with a deep yellow blotch, 

 known as F. refracta alba, which became the usual garden variety. Later F. Leichtlinii was 

 discovered in an Italian nursery. It was a strong growing plant with well shaped blooms, of 

 color varying from sulphur to deep yellow, with deep orange blotch. From this the golden 

 yellow variety, F. Chapmanii was developed. Other crosses and selections show how the type 

 of this plant has departed from that which it originally held. [See Bot. Absts. 3, Entry

 grain by the rod-row method. Jour. Amer. Soc. Agron. 11: 33-47. 2 fig. 1919. — Rectangular 

 plots of grain 2 by 8 rods in size which had received various fertilizer treatments were sampled 

 by taking out rod-rows at certain intervals distributed systematically over the plots. Yields 

 as determined from entire plots were compared with those obtained from the corresponding 

 rod-rows grouped in various combinations. From a statistical study of the data from three 

 different fields it is concluded that for the conditions under which the work was done, 9 rod- 

 rows removed from tenth-acre plots gave as accurate indications of the value of fertilizer 

 treatments as harvesting the product of the entire plots. [See Bot. Absts. 3, Entry 165; 4,
