HORTICULTURE. 1125 



A large number of grafting waxes were tested iu the spring of 1005, and the 

 formula of 2 i)arts resin to 1 i)art beeswax seems to be the best proportion to use. 

 The wax can be made harder or softer by the use of more or less tallow or oil. 

 Adding tallow to the wax does not produce lumps if not used to excess. Adding 

 resin to a soft lumpy wax will render it smooth and i)liabK'. 



An extensive experiment was conducted in the sununer of 100") witii lawn fdats 

 to test the influence of different fertilizers upon the permanence of white clover 

 and certain grasses, and to compare the adaptability of different grasses and 

 mixtures for lawns, golf links, and polo grounds. In all, 33 plats wei'e in- 

 ( hided in the experiment. Fertilizers were used fm'nishing an acid, an alkaline, 

 and a nearly nenti-a! residue. The fertilizer ration used in all eases was as 

 follows: Actual nitrogen per plat, 5.14 oz. ; actual phosi)horic acid, 6.17 oz., and 

 actual potash, 15.42 oz., or at the rate of 50, (iO, and 150 lbs.. resi)ectively, per 

 acre. Notes are given explaining the character of lawn resulting from the 

 different methods of treatment and varieties of grasses used. This experiment 

 is illustrated i).v several plates. 



The market-garden rotation experiment was designed to compare stable 

 manure with chemicals in the growing of market garden crops, a cover crop 

 being introduced wherever practicable. This experiment was begun in 1904, 

 when the crop consisted of corn followed by beans on one part of the plat and 

 beans followed by c-orn on the other. The plat receiving chemicals was on 

 August 10, 1004. sown to timothy and clover, a fair amount of which lived 

 through the winter and was plowed under in June, 1905. The stable manure 

 I'lat received 1 cord of stable manure and the other plat 200 lbs. of chemical fer- 

 tilizer, or at the rate of 10 cords of manure and 1 ton of chemicals per acre. 

 Dwarf Stone tomatoes were planted u])on both plats June 9, 1905, and the yields 

 harvested from these 2 ])lats at the various pickings are tabulated. The plants 

 ui)on the plat receiving the chemical fertilizer made a better start and remained 

 ahead throughout the season. The total picking from August 29 to October 11 

 (jn the stable manure plat was 900 lbs. G oz., while the total picking for the same 

 I)eriod on the chemical fertilizer plat was 1,347 lbs. 5 oz. At the end of the 

 season there were 197 lbs. more green tomatoes and 84 lbs. more rotten tomatoes 

 on the stable manure plat than on the chemical fertilizer plat. A larger pro- 

 jiortion of ripe fruit was obtained earlier in the season from the use of chemicals 

 (ban from the use of stable manure, which is believed to be due to the influence 

 of nitrate of soda in hastening the maturity of the tomatoes. 



A score card similar to the one used for strawberries has been adapted for 

 rasi)berries and is shown here containing the scale of poin"ts and a key for the 

 descri|)tion of the plant. 



The work with sterilized soil was continued in 1905, in which the methods 

 of treatment were those foi'merly used (E. S. R., 17, p. SG2), and are as follows: 

 (1) Unsterilized. (2) sterilized and handled while hot, (3) sterilized and handled 

 cold, (4) sterilized and sjirinkled lightly with rich unsterilized soil to introduce 

 soil organisms. (5) sterilized and treated with nitrate of soda. The work is 

 discussed in detail. The crops used were radishes and lettuce, and the weights 

 at harvesting obtained from the various soils are presented in tabular form. 

 The radishes obtained fnmi the sterilized soil, handled hot, were not only 

 larger, iait brighter in appearance, and those secured from sterilized soils, 

 sjjrinklcd willi garden soil, were next as to weight. The lettuce in all plats 

 made a very jioor growth, and all the lettuce*was pulled and the i)lats rei)lanted 

 with turnips on August 31. Judging from the weight of the turnips, the leaves 

 of which were badly eaten by worms, the roots secured from soils sterilized and 

 handled hot and from those sterilized and handled cold were practically the 

 same. The radishes were succeeded |»y Marguerite carnations, and the number
