Control oj flumldil tj Conditions in Leninn Storaije. — This is dealt with Ijy 

 Mr. A. D. Shame) in an article appearino; in the March, 1920. issue of tlie Cali- 

 fornian Citrogivpli. A description is given of the instruments and means used foi- 

 regulating humidity conditions in the stor^ige rooms and among the numerous 

 conclusions arrived at it is shown that uniformly high humidity gave the best 

 resxdts witii the fruit, and tliat the late of natural curing depends uj)on the 

 temperature at which tlie fruit is held. At !)3° F. the green fi-nit cnivd within 

 nine days. 



Wort Disease of tin' I'utato. — The .Jannary, 1!)20, number of the Scottish 

 ■Journal of Agriculture, issued by the Board of Agriculture for Scotland, deals 

 with the scheme of certification of growing crops which are immune to the 

 disease. The inspection of growing crops was terminated in September last 

 and revealed that stocks of the older vari.^ties are far nun-e impure than those 

 of the newer varieties. Mixed stocks are being weeded out, older varieties are 

 being freed from admixture, and new varieties are being maintained in high 

 state of purity. Planting fiom certified stock of inimnn(> varieties will ultimately 

 lead to al)solute pure sLock reaching the market. 



Conmlhin docrnin' n* (•ruin El< rotor. — We learn from the Conodion 

 .{(jrirultuiol Gazette of February, 1920, that the Canadian Govertiment has 

 erected and is operating five large elevators in the Dominion. The elevators 

 with fundamentally different functions to fulfil may be classified under three 

 headings of " Pul)lic. Terminal," "Interior Terminal." and "Transfer." The 

 Public Terminal Elevator at Port Arthur was completed in 1913, cost $1,500,000, 

 and has a capacity of 3,250,000 bushels of grain with a woi-khouse caijacity of 

 750,000 bushels. Two Interior Terminal Elevators at Moosejaw and Saskatoon, 

 Sask., respectively, were completed in October, 1914, costing $1,000,000 each! 

 the capacity of each being 3,50O,(J00 bushels with a \vorkhouse accommodation 

 of 112 bins for 500,000 bushels. Another elevator of the same type with a 

 capacity of 2.500.000 bushels was completed in 1915 at Calgary, Alta., costing a 

 little over $1,000,000. The third class, or Transfer Elevator, was erected in 

 1916, at Vai-couver, B.C., at a cost of $800,000. 



Mdk Produrts in. America, and Europe. — Mr. W. Dempster, of the New 

 Zealand Department of Agriculture, contributes a very interesting article to the 

 February, 1920, Journol of .i(jrirulture of Xew Zealand, on his trip to America 

 and Europe investigating the manufacture and marketing of milk powder, sugar 

 milk, and other branches of dairying as carried out in those countries. A 

 review is given of the manufacture in the United States of skim-milk powder, 

 butter, Swiss cheese, sugar of milk, "jack cheese," muriatic-acid casein, con- 

 densed milk, casein, etc. English and Scotch methods of milk powder pioduc- 

 tion are dealt with, Holland being visited in the same connection. The author 

 giv-s a detailed account of his liTiding couceruing production and all factors 

 influencing iiroduction and marketing.
