Original copies in printed paper covers are filmed beginning with tiie front cover and ending on the last page with a printed or illustrated Impres- sion, or the back cover when appropriate. All other original copies are filmed beginning on the first page with a printed or illustrated impres- sion, and ending on the last page with a printed or illustrated impression. The last recorded frame on each microfiche shall contain the symbol — ^- (meaning "CON- TINUED"), or the symbol V (meaning "END"), whichever applies. Maps, plates, charts, etc.. may be filmed at different reduction ratios. Those too large to be entirely included in one exposure are filmed beginning in the upper left hand corner, left to right and top to bottom, as many frames as required. The following diagrams illustrate the method: 1 2 3 1 2 4 5 L'exemplaire filmA fut reproduit grdce ^ la gtn^rositA du: Bibliothe(,>:3 Agriculturt Canada Les images suivantes ont 6\i reproduites avec le plus grand soin. compte tenu de la cordition et de la nettet6 de l'exemplaire filmi, et en conformity avec les conditions du contrat de filmage.

This praetic assures an abundant supply of decaymg vegetablo matter which, bem.l. >* increasing the water-holding capacity of the soil supplies, aftjT It has been rendered availablr by tho action of soil bacterm, dv fertiluing requin-ments of the crop. Again, the deep feedm^ roots of the clover not only loosen up the soil to a greaUr depth, thus making conditions ideal for the development, of p<-rfect shapf'd potato.B but also assimilate some of the '""^ fi>;t^|f|nK ingredients of the sub-soil, which are r.ndiml available for the plant by the decomposition of the clover sod. i. u i Commercial fertilizers should not be applied as a substitute for manure, but should »).• used as a supplement to it. In such ease, the fertilizer applied should be one that is readil.s available, so that the potato plant may utilize it while the decaying vegetable matter (manure and clover sod), are being rendered available by the soil bacteria. SEED 8ELECT1()N AND TREATMENT. Everv potato grower should prnctice a thorough method of selection, which shoul.l not be confined io the bin in the c.llar. but to the growinu crop. Kirst, the grower should go over his potato field, carefully sch-eting suffieient vigoious and disease-free hilU to plant an area large These are harvested and stored separately from the main cropnnd pluntcd in the spring on nn an'a si«eially prepared and given thorough attcnl ion ' u'ing and controlling of insects and diseases.

Experiments have proved the following: First, sprouting in storage decreases be.th the vitality and yield of the succeeding crop. Second, sets should be of gpod size with from two to thr^e eyes, a miHliumsizid potato making four sets. Third, planting should be done as soon as possible after cutting, to preser\-e moisture in the potato. The drying out ot the seed for a single dav mav decrease the yield by one-third. If w< ather conditions pnvent plant- ing, potatoes should b.' "sprinkled with ground plaster or slacked lime to prevent evaporation. PLANTING. Potatoes thrive in loose soil; therefore, spring r.lough. A clover sod that has b( cultivator should be run through to loosen tho soil left bare by the use of the hiller as from this bare unmiilehe0 to 200 pounds, covering completely wtato tops with spray.
