THE SUGAR INDUSTRY 



THICK CANES vs. THIN CANES 



By Arthur H. Rosenfeld, Director of the Agricultural Experiment Station, Tuoum^n, Argentina. 



Below are given the results of a series of experiments, made at the Tucuman Agricultural 

 Experimental Station, comparing the relative merits for planting of thick and thin sugar canes. 

 The stalks planted of both classes were all carefully chosen, and were in good condition and 

 practically free from borer infestation and disease. 



These results represent the averages of the plant and the first year stubble yields. The 

 experiment was started in July, 1911, and the preparation of the soU, cultivation, irrigation, 

 fertilization, and harvesting were more or less the same as those described in the article on 

 "Disinfection before Planting," published in a recent number of the International Sugar 

 Journal* 



Average Yield of Plant and Stubble Cane.

Thick canes 38085t 0.65 15.2 11.6 0.4 76.3 



Thin canes 37634 0.63 15.8 12.1 0.3 76.8 



It would appear from these results that, provided the stalks planted are healthy, the 

 thickness of the cane used is of little importance. The size of the stalk does not indicate the 

 hereditary potentialities it may possess. Therefore we may assume that a rigorous selection 

 from the point of view of healthy condition and freedom from disease is much more valuable, 

 than a selection regulated merely by the size of the canes. 



A new series of experiments along these lines has been commenced this year. — International

PRECIOS DE LA QUINCENA 



La primera quincena de Enero, que hoy finaliza, ha resultado algo mejor para nuestros 

 azucares que la pasada, segunda de Diciembre, habicndose cotizado en ella con firmeza y 

 registrandose una fraccion de alza, si bien esta y otra mas fuferon perdidas en los ultimos dias. 



La marcha de los precios fue como sigue: Abriendo a 5 5/8 rls. por arroba de azucar 

 centrifuga en almacen paso el quinto dia, que fue el 7, a 5% donde se mantuvo cuatro dias 

 mds, hasta el 12, comenzando seguidamente a retroceder a 5 5/8 y a 53^, donde queda. 



Resulta de todo ello que el promedio de precio para la quincena es de reales 5.656, contra 

 rls. 5.577 de la segunda de Diciembre o sea con una mejoria de 79 milesimas de real. 



En Nueva York abrio la centrifuga en plaza a cts. 4.01 por lb. y a 3 cos to y flete y despues 

 de haber estado en 4.11 y 3. 3/32 respectivamente comenzo a declinar estando el 14 en 4.04 

 y 3 1/32.

PRICES OF THE FORTNIGHT 



The first fortnight of January, ending today, has resulted somewhat better for our sugars 

 than the last half of December, being quoted with firmness and showing a slight advance, 

 although this and more were lost in the last few days. 



The advance in price was as follows: Opening at 5 5/8 rls. per arroba of centrifugal sugar 

 in warehouse, it went on the fifth day, which was the 7th, to 5^, where it remained four days 

 more, until the 12th, commencing then to fall back to 5 5/8 and 5}4, where it remains. 



The result is that the average price for the fortnight is 5.656 reales, against rls. 5.577 of 

 the second half of December, that is, an improvement of 79/1000 real. 



In New York centrifugal sugar opened in the market at 4.01 per lb. and at 3 cost and freight 

 and after reaching 4.11 and 3 3/32, respectively, commenced to dechne, being 4.04 and 3 1/32 

 on the 14th.
