into decay in a very short time. Wrap the fruit singly in paper and place? 

 in shallow hoxes, not over two <loop, and cover closely, carefully excluding 

 light and air for three or four weeks. Then onen out and dry the fruit, re- 

 wrap in paper and keep in a building at a low temperature until finally 

 ready to market. 



A simple and sometimes as satisfactory method is to gather the fruit in 

 piles under the trees, where it will he completely shaded by the foliage. 

 covering the fruit with a thin layer of straw or other light material. This 

 open-air cubing progresses well, the fruit becoming beautiful in color and 

 of excellent quality, if of a good variety. There are half a dozen methods 

 that yield good results, and doubtless future experiences will develop im- 

 provements on existing methods. If gathered at the right moment, "as the 

 color begins to turn, lemons may be kept for months, ami they will improve 

 in market qualities, by a thinning and toughening of the skin, and by in- 

 crease of juice." The Sicily process for curing lenmns consists principally 

 of a six mouths sweat in a shadv place. A moist atmosphere, cool storage 

 and protection from light a «d drafts of air seem to be vital points.

SEVENTEEN-YEAB LOCUST. 



During the present rear two broods of the periodical cicada or so-called 

 " seventeen-vear locust" (Cicada septendeeim), one of the seeenteen-yenr 

 race and one of the thirteen year race, will make their appearance in differ- 

 ent parts of the countrv. Prof. C. V. Riley, U. S. entomologist at Wash- 

 bngton, D. C., would be glad of evidence as to the appearance or non-ap- 

 pearance this year of the insects in the localities noticed below. 



Tiiirtekx-year race is expected in Lowndes Co., Alabama; Cobb and 

 Cherokee Co*?., Georgia; Lincoln Co., Tenn. ; Lincoln and Moore Cos.,X. C 

 Any evidence giving the extent of territory over which they appear in your 

 county or state, or any well attested dates of their appearance in previous 

 years, will be thankfull}' received and appreciated, regarding either this or 

 the following: 



Seventeen-year rack. The appearance of this in Colorado. Kansas 

 and Kentucky would be especially interesting Expected in portions <>f 

 North Carolina, Virginia, District of Columbia, Maryland, Indiana and

EXHIBIT OF THE GERMAN KALI WORKS. 



Among the agricultural exhibits at the World's Fair one of the most 

 interesting is that of the German Kali Works, in which the produces of the 

 great potash mines are displayed. These mines are located at Stas<furt, 

 Germany, and furnish, as is well known, nearly the entire supplv of potash 

 — a valuable plant food and ingredient of everv complete fertilizer. The 

 potash coming from this source is found in large quantities in tin 1 form of 

 solid masses of potash salt, most of which are subjected to a manufacturing 

 process by which they are concentrated and made ready for use. The ex-
