the former fruit was sliowu to contain 0,232 per cent of .suli>linric acid 

 (equivalent to about 25 grains of oil of vitrol i)er pound) and the latter 

 0.34G per cent of sulphuric acid (mostly free). In most Euroi)eau coun- 

 tries the sale of sulphured fruit is forbidden. California fruit growers 

 are advised to make an eftbrt to educate the public taste so that it will 

 prefer " healthy, brown, high -flavored fruit to the sickly-tiuted, chemi- 

 cal-tainted i)roduct of the sulphur box."

The conservation of wines, E. W. Hilgaed, Ph. D. — This bulle- 

 tin was prepared to combat "irrational prejudices against the treat- 

 meut of wines by purelj" ])hysical means, '■ such as are commonly em- 

 ployed ill the wine producing countries of Europe, "especially' in those 

 in which the prevalence of climatic conditions similar to ours renders 

 the conservation of dry wines not fortified a matter of well-recognized 

 and acknowledged difficulty." The process of wine heating or "pas- 

 teurizing," direct treatment with an electric current, and the steriliza- 

 tion of wine by filtration through porous porcelain, are described and 

 discussed, principally by means of quotations from foreign sources. An 

 electro-magnetic process devised by Dr. Eraser of San Francisco, is also 

 favorably referred to.

Sugar-beets, C. L. Ingersoll, M. S. (pp. 3-0).— In Colorado, where 

 irrigation is practiced, the conditions of soil and climate make it easy 

 to raise large crops of beets. " Not only is the total yield heavy, but 

 single specimens often grow to wonderful size." The dry and clear 

 weather which prevails in this State in the autumn also favors the 

 formation of sugar in the beets. Comparison of climate and other con- 

 ditions in Colorado with those of the beet-growing regions in Europe 

 is favorable for beet growing in Colorado. The method of culture rec- 

 ommended is as follows : 



" (1) Prepare a deep and well-pulverized seed bed. 



" (2) Sow in drills 18 to 20 inches apart, so as to admit of horse culture 

 between the rows, nsing from 7 to 8 pounds of good seed per acre. 



"(3) Irrigate judiciou.sly and keep clear of weeds. Cultivate thor- 

 oughly during their early growth. 



" (4) When well up, thin so that there shall be one thrifty plant every 

 G or 8 inches (some say 10 or 12), and take care not to injure the plants 

 in this process. 



" (5) In cultivation take care to preserve the leaves and to throw some 

 earth on the plants each time. The portion of the beet which grows 

 above ground does not contain much sugar. 



" (G) Harvest when rii>e, and preserve free from frost."
