inainecl in good state of preservation for a storage period of two months, 

 possessing a normal flavor. The flavor of the fruit was slightly flat when 

 subsequently exposed to ordinary temperature for a period of two days. This 

 was more noticeable with fruit stored at 3G°. Perfectly ripe mangoes pre- 

 served the normal texture and flavor for a storage period of 35 days, after 

 which the flavor deteriorated slightly. 



Experiments with pineapples indicate that half-ripe and ripe pineapples may 

 be stored for six weeks at a temperature of 32° without harm to the color or 

 flavor of the pulp of the fruit. The only change is a slight deadening in the 

 color of the rind. The avocado seems to be well adapted to cold storage at a 

 temperature ranging from 32 to 3G° for a period of at least two months. 



Seed from several varieties of star apples held at 45° for various periods up 

 to 25 days germinated promptly to the extent of 90 per cent, but seed from 

 fruit held for more than 30 days in cold storage failed to germinate at all. 

 Similarly with the seed of avocadoes, no germination took place from fruit held 

 longer than 20 days at a temperature of 32°. 



Further researches on some statistics of Coffea, P. C. van dee Wolk 

 (Zt.scltr. IniJuktivc Abstain, u. Vcrcrbimf/slchn; 13 {lOlJf), A'o. 1-2, pp. 176- 

 ISi). — In continuation of previous studies (E. S. It.. 31, p. 142) the author here 

 presents some correlation tables referring to the relation between the number 

 of " bloomheads " per leaf axil and the number of blooms per " head " in 

 Coffea quillou. The author is of the opinion that the correlation coeflicient is 

 of no value to the physiologist. 



In interpreting the correlations existing in the present tables a series of cor- 

 relation diagonals is used.

FORESTRY. 



Sixth annual report on forestry operations, E. Skckest {Ohio Uta. Bid. 216 

 {tOlJf), pp. 317-330).— lu continuation of previous reports (E. S. R., 29, p. 746) 

 a general statement is given of progress made in the operation of forest 

 nurseries, free distribution of stock, forestry experiments, farm woodlot prob- 

 lems, woodlot pasturage investigations, cooperative work with institutions 

 and municipalities, assistance rendered in foi-est planting operations and educa- 

 tional work, drainage basin and commercial tree studies, and wood utilization. 

 Suggestions are also given relative to needed legislation for the advancement of 

 forestry in Ohio. 



[Report on] tree planting, B. Aune {U. S. Dept. Agr., Bur. Plant Indus., 

 Work Belle FourcJie Expt. Farm 1913, pp. 15, 16). — Notes are given on the 

 condition and behavior of trees for shade, ornamental, and windbreak purposes 

 that have been tested on the Belle Fourche Experiment Farm. S. Dak., since 

 1900. 



In the test being conducted on dry land the only varieties that came through 

 the severe winter of 1912-13 without any winterkilling were the green ash, 

 Siberian pea, honey locust, and red cedar. Of these species the green ash and 

 Siberian pea are the most hardy and desirable. The work with trees under 

 irrigation has not progressed far enough to warrant any specific recommendation.
