1070 EXPERIMENT STATION RECORD. 



protection are described. The practice of laying down is begun on trees the first 

 years they are set in the orchard. Some time in November after the leaves have 

 fallen a circle of earth about 4 ft. in diameter is removed from around the tree. 

 AYater is then poured in and the tree worked back and forth until the roots are 

 loosened and the tree bent to the ground in the direction of least resistance. The 

 branches are then tied together and the tree covered with burlap held in place with 

 earth. A light layer of earth is then thrown over the tree. As the blossom buds 

 begin to open the following spring the covering is loosened to admit of light and air. 

 The blossoms are exposed to the sun gradually and after all danger from frost is 

 considered over they are raised to an upright position and held in place by a couple 

 of props. In placing the trees in the upright position the groiind is again watered 

 and when wet enough the trees are raised without difficulty. Old trees can not be 

 very successfully handled in this manner. Tlie practice must be begun with the 

 young trees and continued. It is stated that the process seems to be in no way 

 detrimental to the health of the trees since they live as long and bear as much fruit 

 according to the size of the top as those grown in peach sections. The author 

 believes that by laying down the trees in winter according to the plan outlined, 

 peaches may be grown in nearly all parts of Colorado. 



A remarkable pineapple [Queensland Ac/r. Jour., 12 {1908), Xo. 4, p- 254)- — A 

 curious pineapple having the characteristics of the smooth-leafed Queen and the 

 ordinary rough-leafed pine is described. The fruit is described as being full of seeds, 

 the juice very al)uiidant but of poor flavor. 



A remarkable mango {Queensland Agr. Jour., 12 {1903), No. 4, p. 254, pi- 1)- — A 

 mango fruit having a kind of horned jirotuberance is descriljed. The fruit is borne 

 on a tree between 4 and 5 years old and yields quite abundantly. The description 

 is accompanied by a full-page illustration of the fruit. 



Report of central station at Ames, H. C. Price {Trans. Iowa Ilort. Soc, 37 

 {1902), pp. 219-221). — Notes on the crosses made between varieties of apples, plums, 

 and cherries, and on the distribution of orchard pollen among fruit growers. An 

 experiment in stratifying whole fruits in sand out doors, stratifying the core of the 

 apple containing the seed, and stratifying the seed after tiiey have l)een removed 

 from the apple resulted in favor of removing seeds entirely from the pulp before 

 stratifying. 



An Iowa plant breeder; some of his creations, II. C. Pkice {Rural New Yorker, 

 62 {1903), No. 2776, pp. 277-279, figs. 3). — An account, with ilhistrations and descrip- 

 tions, is given of the varieties of crab apples, grapes, and dewberries originated by 

 Newton K. Fluke in Iowa. 



The influence of stock on scion, Leclerc du Sablon (f'ompt. Tlcnd. Acad. Sci. 

 Paris, 136 {1903), No. 10, pp. 623, 624). — A pear grafted on a quince ]troduces larger 

 fruit and yields mf)re abundantly than ^^'hen grafted on pear seedlings. The author 

 studied One of the causes or this phenomenon. He found that the reserve material 

 accumulated during the autunni and winter in the trunk and limbs was considerably 

 greater in the jDear grafted on the quince than in trees grafted on pear seedlings. In 

 the spring, therefore, when growth starts, the trees grafted on quince are better able 

 to contribute to the formation of fruit a large quantity of food than trees grafted on 

 pear seedlings. No cause could be assigned as to why more starch should accumulate 

 in the trees grafted on quince than in the trees grafted on pear seedlings. 



Hardiness of some grafted stocks, J. M. Guillon {Rev. Vii., 19 {1903), No. 4S2, 

 pp. 301-305, figs. 6). — An account of the growth of several species of grafted stocks 

 in shallow and deep soils. 



Comparative structure of calluses in grafted plants, L. Daniel {Rer. Mt., 19 

 {1903), No. 482, pp. 324, 325). — A microscopical stu<ly of the calluses of a large num- 

 ber of grafted plants. 



Grafting nutmegs {Agr. Neirs [Barhados'], 1 {1902), No. 6, p. S4). — Detailed 

 directions are given for grafting nutmegs.
