pounds, the consensus may be expressed 

 in quoting from an Ohio Station bulle- 

 tin: "In actual praetice the experi- 

 ments made by the Ohio Experiment 

 Station have shown no praetical superi- 

 ority of one form of lime over the other, 

 provided the limostone has been so 

 ground that eighty per cent of it will 

 pass through a sieve having 100 meshes 

 to the linear inch and provided, of 

 course, that the two materials have 

 been used on the basis of the actual 

 calcium contained." In other words, 

 either limestone or burned lime may bo 

 used, provided the limestone is reason- 

 ably pure and is finely ground, and ])r()- 

 vided it is kept in mind that 100 pounds 

 of limestone equal fifty-six pounds of 

 lime oxide. 



Slaked lime also may be used. As 

 said above, slaked lime is formed when 

 water combines with the lime oxide. 

 Air-slaked lime is formed when the 

 oxide is exposed to air. In the case of 

 air-slake<l lime, tlie product has been 

 formed more slowly, for the water was 

 taken from the air and, consequently, 

 the heat generated in the process is 

 not apparent, but tlie ])roduct is the 

 same as when the oxide is slaked by 

 adding water. C(ini]iared with the oxide, 

 its value, however, is less. The rela- 

 tion between the two is as 100 to 75.7. 

 In other words, two parts of oxide are 

 equal to three of slaked lime. The re- 

 lation between the carbonate (lime- 

 stone), the oxide (burned or quicklime), 

 and hydrated lime (slaked lime), then, 

 is as follows: TOO ])ounds of carbonate 

 are equal to seventy-six ])ounds of hy- 

 drate or fifty-six pounds of oxide. 



How to Use Lime. 



When contem])lating the use of lime, 

 certain facts should be kept in mind. 

 In the first place, lime in any form 



ter is supplied by means of natural 

 manures and such commercial fertilizers 

 as dried blood and tankage. If suf- 

 ficient manure is not at hand, the plow- 

 ing under of green crops, such as 

 clovers, cowpeas and other plants, is 

 the only other method of supplying soils 

 with organic matter. Lime will hasten 

 the decomposition of this organic mat- 

 ter and make the nitrogen-containing 

 materials soluble and, hence, available. 

 Quicklime or lime oxide will bring 

 about decomposition more rapidly than 

 will lini(>stone. It is, therefore, more 

 effective ill producing available nitro- 

 gen (luickly. However, since its ac- 

 tion is rai)id, quicklime must be used 

 with caution. It should not be mixed 

 with manure or other organic fertil- 

 izers, such as dried blood or tankage, for 

 the nitrogen in these substances is 

 liberated rapidly, as a result of the ac- 

 tion of the quicklime, and thus it may 

 be lost before the plant can use it. 

 The effects of overfeeding with nitro- 

 gen may also naturally follow. The 

 same rule applies also if ammonium 

 sidphate is used as a fertilizer. In 

 order to hasten decomposition of ma- 

 nure, quicklime may be used in small 

 quantities, but in this case the lime 

 should be added before the plants are 

 l>nt in the soil and precautions should 

 lie taken to prevent the loss of the nitro- 

 gen. 



What to Avoid. 



Lime in any form should not be mixed 

 with or applied at the same time with 

 acid phosphate. This is because the 

 lime tends to change the water-soluble 

 |ihosplioric acid to an insoluble form, so 

 that the plant cannot use it. Aside 

 from this fact, limestone may be ap- 

 ])lied at any time. The oxide form, 

 especially if the unslaked form is used, 

 should, however, not be applied at a

should not be applied to soils which 

 are deficient in organic matter. Lime 

 in such soils would do only harm. The 

 first essential, perhaps, of a soil is that 

 it must contain organic matter in order 

 to support plant growth. Organic mat- 



time when it will come in contact with 

 seeds or young roots of plants. As 

 stated above, the oxide form of lime 

 should not be mixed with stable manure. 

 The quantity of lime to apply de- 

 pends upon the soil, and on the form of 



lime used. Large quantities of lime- 

 stone seem to do no harm, but the re- 

 sults are not necessarily better than 

 when smaller quantities are applied. 

 From one to three tons per acre every 

 few years is in most cases ample for 

 field soils. In case burned lime is used, 

 half the amount is used. For soils in 

 greenhouses a sprinkling of from ten to 

 twenty pounds of limestone, or less than 

 half that amount of burned lime, to 

 each 100 square feet is ample. 



GUDE AT THE WHITE HOUSE. 



The illustration on this page shows 

 the Washington representative of the 

 S. A. F. photographed with President 

 Harding on the White House lawn on 

 the occasion of the Eotary Club's pres- 

 entation of the statue, "Spirit of Bo- 

 tarv, " which the president holds in his 

 left hand. 



The statue, "Spirit of Rotary," was 

 brought from Honolulu by Charles W. 

 Brown, secretary of the Chamber of 

 Commerce, immediately on the presi- 

 dent 's right, and Mr. Burnham, the 

 sculj)tor, who stands next to William 

 F. Gude. 



TOLEDO, O. 



The Market. 



The heavy rains throughout last 

 week were in marked contrast to the 

 record-breaking heat wave of the pre- 

 vious week. As a result, outdoor flowers 

 of all kinds, especially peonies, were 

 just about ready for Memorial day. 

 However, the rains did much to ruin 

 the flowers, and a great many people 

 resorted to bedding stock in place of 

 flowers. 



The demand for plants for decorative 

 purposes has been heavier than last 

 year, and geraniums have been almost 

 cleaned up. There will be plenty for 

 everyone, however, as a number of the 

 growers have stock that will bloom 

 soon. 



The cut flower market showed a 

 marked drop in wholesale prices, when 

 they are compared with those of Mothers' 

 day. Koses were plentiful. Carna- 

 tions were soft, but held their price 

 well. Sweet peas are showing the ef- 

 fect of the heat wave and will soon be 

 done indoors. Wild daisies, which have 

 been given cultivation, are good stock 

 now, helping considerably for making 

 bouquets, etc., for inexpensive work. 

 Cornflowers from coldframes are in 

 good demand. 



Various Notes. 



John Lambert, formerly with Mrs. J. 

 B. Freeman and now with the Ove 

 Gnatt Co., Laporte, Ind., spent a few 

 days' vacation in Toledo. His good 

 friend, Tim Magee, of the Scottwood 

 Greenhouses, commandeered his serv- 

 ices over Memorial day. Business at 

 the Scottwood Greenhouses is con- 

 stantly on the upward trend. 



W. F. Krueger, who had an optical 

 operation in January, is able to with- 

 stand the glare of the greenhouse light 

 by using black glasses. 



Schramm Bros, report the call for 

 bedding stock heavier than it was last 

 year. Business in general is far ahead 

 of that up to this time last year. 



Metz & Bateman have had an unusu- 

 ally heavy call in funeral work.
