each lot being changed on each tree so 

 that on one tree the poorest yielding scions 

 would be on the north side, while on the 

 next tree they would have a southern ex- 

 posure, etc. The limbs selected for graft- 

 ing were as uniform as possible. The re- 

 sults from this check follow : 

 Yields for Five-Year Period, 1911 io 1915 

 Inclusive. 



It has only been possible to use the re- 

 sults for the first five year-period, as 

 since that date pilfering and accidents have 

 rendered the records from these trees un- 

 reliable. It will be noted, however, that 

 here again there is a distinct difference in 

 favour of the two high yielding progenies, 

 althougli the progeny from the largest and 

 most regular bearer has given a larger yield 

 than that from the heaviest yielder. Ne- 

 vertheless there is a distinct lack of pro- 

 ductiveness of the progeny from the poor- 

 est yielding parent.

THE STORAGE OP ICE. 



The heated period of the past summei- 

 must have convinced at least the majority 

 of people of the necessity and value of hav- 

 ing a supply of ice for domestic use. On 

 that account a bulletin issued by tlie Dairy 

 and Cold Storage Branch of the Domiuion 

 Department of Agriculture, Ottawa, des- 



cribing Simple Metiiods for the Storage of 

 Ice is of special and immediate interest. 

 The bulletin points out that any unoccupied 

 corner of a shed may be made to serve the 

 purpose. A rough board enclosure ten feet 

 square and eight feet high will hold suf- 

 ficient to provide 50 pounds per day for 

 130 days after allowing for a reasonable 

 amount of wastage. An important fact to 

 be remembered is that the smaller the 

 quantity of ice stored the larger is the pro- 

 portion of waste. The bottom of the en- 

 closure should be covered with a foot of 

 saw-dust, and a foot of space left between 

 the boai'ds and the ice which .should also 

 be filled with sawdust. The ice should be 

 similarly covered. The drier the sawdust 

 the better. If the soil beneat;i the enclos- 

 ure is impervious clay, a layer of gravel 

 under the sawdust is advisable. If sawdust 

 is not obtainable, planer mill shavings will 

 serve. If neither is to be had, two feet of 

 marsh hay or any fine wild hay that grows 

 in low places well packed will answer. If 

 it is thought necessary to erect an ice- 

 house, the roughest kind of a shed that 

 will resist the weather is all that is re- 

 quired. 



SOIL DRIFTING REMEDY. 



Strip Seeding Experiment Commenced at 

 Nohleford. 



Strip seeding as an experiment to 

 combat soil drifting has been commenced 

 by the Noble Foundation at Nobleford, 

 C. S. Noble announces. This experiment 

 is a process by which crop is sown in 

 strips at intervals across the land, and 

 was one discussed by .soil drifting ex- 

 perts at the irrigation convention in Leth- 

 bridge last year. Mr. Noble is the first to 

 introduce the experiment in Southern Al- 

 berta. 



He has large areas in rye this fall and 

 has planted the crop in .strips twenty rods 

 wide and twenty rods apart across the 

 western i)oi-tions of his .sections in "crop. If 

 wheat is i)lanted in the otlier spaces, this 

 method gives an alternative of .stubble and 

 crop, since rye matures early in the sum- 

 mer and wheat is harvested in the fall, tlius 

 giving an effectual protection against 

 drifting. The Nobleford farms have 

 about 11,000 acres in rye this fall.
