The manuring of market-garden crops, W. Dykk {/aiikIdh: ]'iiit(iii .(• Co., Lt<f' 

 189,S, j>f>. 64). — The antiior has i)rought together the results of a large number of 

 experiments in fertilizing all the more usual garden crops, including cabbage, onions, 

 lettuce, Brussels sprouts, cauliflowers, broccoli, asparagus, rhubarb, Jerusalem arti- 

 chokes, strawberries, (Tlo])e artichokes, carrots, j)arsnips, spinach, beets, celery, and 

 potatoes. The experiments, on the whole, bring out the fact that market gardeners 

 fre(|uently jiay too large j)rices and use too large amounts of barnyard mamire in 

 their gardening oj)erations. For some crops it wa-s found that conunercial fertilizers 

 used alone were most economical, but that on the whole the best method of manur- 

 ing was to I'ombine the use of a moderate iiuantity of l)arnyard mamire with the 

 liberal use of commercial fertilizers. 



The artichoke, J. MATHiAri) ( Rir. Jlort. d 1'//., 3S {1001), Xo. II, p/,. ..'/o-JUl).— 

 A paper on varieties, methods of culture, including care over winter, and the disea-^es 

 and insects affecting. 



Forcing beans, R. Priebk {MoUer's Deal. Gnrl. Zl«j., Id {1901), No. 47, pp. 

 567-n70). — Directions are given for forcing Ijeans in the greenhouse. Seed ?> years 

 old is preferred in this work. 



Cauliflower, H. H. Hime {Florida ,Sta. BiiL n9, pp. 4J,5-4-i'9, y>/.s. .^,Ji(j. /).— Full 

 directions are given for the culture, fertilizing, and marketing of cauliflower in 

 Florida, with an account of the chief insects affecting and methods for their control. 

 Work at the station has shown that the cauliflower can l)e profitablj' grown in 

 Florida. Varieties of the forcing type, like P^xtra Dwarf P^rfurt, Early Snowball, and 

 Dry Weather, are considered most desirable. The seed used should be tlie best. Seed- 

 ing the first week in August was found the earliest date at which a good stand of 

 plants could be secured. About 6 months are required between the time the seed is 

 sown to the maturity of the crop. At transplanting time the leaves should be cut 

 back from one-half to one-third. In the station work, sufficient well-rotted stable 

 manure is used to cover the ground 1 to li in. deep. This is supplementeil by a 

 fertilizer mixture made up of 250 ll)s. nitrate of soda, 400 lbs. cotton-seed meal, 

 600 lbs. acitl phtjsphate, and 400 lbs. high grade sulphate of potash. The stable 

 manure and half the commercial fertilizers are applied liroadcast -' to H weeks l)efore 

 planting and thoroughly worked into the soil. The remain<ler of the fertilizers are 

 applied Ij to 2 months after the plants are set by scattering it around them and 

 lightly raking in. If the soil is sufficiently rich in vegetable matter the barnyard 

 manure is omitted and more commercial fertilizers added. 



Celery culture, W. R. Beattie ( ('. S. Dept. Aijr., Farmers' But. 148, pp. 32, fiyn. 

 7). — Popular discussion of the growing of celery, including notes on disease.^ and 

 insects affecting, i)roHts in the business, varieties, and marketing. 



Celery growing in Orange County, C. F. Heil {Pacljir Rural I'res.^, i>..' (1901), 

 Xo. in, jip. 244, 245). — A jmper on this subject dealing with cultural methods and cost 

 of growing. The cost of growing an acre of celery in Orange County, California, 

 placing the rent of land at *30 per acre, is given 2^ $75. From an acre 1,000 to 

 1,500 dozen bunches are obtained, for which buyers pay from 10 to 18 cts. per dozen.

 chemical transformati<»n that takes place in i)lants which jtroduce a secondary gn)wth 

 at the expense of the reserve material of the root. Chicory was the subject chosen, 

 and analyses are given of chicory roots before and after having produced a secon<l
