latitnilo. Ill otlior words, I liclicve tluit it is iiiiitossihle to secure stock from tliflfereut 

 growers which is iiuiforiii enough to allow of comparative experiiiieiitatiou ; auilthis 

 is as true iu other plants as in potatoes. If this generalization is correct, we must 

 modify many of our methods of experimentation. In order to secure a uniform stock, 

 it must he grown iu the same place and uuder the same conditions for several years, 

 and this can then he distiihuted to various growers and after a time returned to ho 

 grown again side hy side for comparison. And even here it will he diflicult to 

 eliminate uncertainties. But in this line we shall now work upou our studies of the 

 iuHueuce of latitude upon plants. 



lifOTES UPON METHODS OF HERBACEOUS GRAFTING, L. H. BAI- 

 LEY, M. S. (pp. 175-177). — Brief notes are given on experiments in 

 grafting, performed by J. ii. Locbary under the supervision of the 

 author. 



The experiments were uudertakeu primarily for the jiurpose of learning the best 

 methods of grafting herhs, hut a secondary and more important object was the study 

 of the reciprocal inlluences of stock and scion, particularly iu relation to variegation 

 and coloration. This second feature of the work is still under way in one form or 

 another, and we hope for definite results in a few years. * * * 



Six hundred grafts were m;\de in our trials last winter. It was found that the wood 

 must he somewhat hardened to secure best results. The very soft and flabby shoots 

 are likely to he injured in the operation of grafting, and union does not take place 

 readily. * * * Various styles of grafting were emjiloyed, of which the common 

 cleft and the veneer or side graft were perhaps the most satisfactory. In most 

 instances it was only necessary to hind the parts together snugly with bass or 

 raflia. * * * 



[Among the experiments were the following:] Tomatoes upou potatoes and pota- 

 toes upon tomatoes grew well and were transplanted to the open ground, where some 

 of them grew, flowered, and fruited until killed by frost. The tomato on potato plants 

 bore good tomatoes above and good potatoes beneath, even though no sprouts from 

 the potato stock were allowed to grow. Peppers united with tomatoes, and tomatoes 

 wiib peppers. Egg-plants, tomatoes, and peppers grew upon the European husk 

 tomato or alkekeugi {PhijsaUs ulkelcengi). Peppers and egg-plants united with each 

 other reciprocally. Pumjikin vines united with squash vines, encumbers with 

 cucumbers, nnisk-melons with water-melons, and musk-nielous, water-melons, and 

 cucumbers with the wild cucumber or balsam apple (Ecliinoci/stis loha(a). 



Another interesting feature of the work was the graftiug of one fruit upon another, 

 as a tomato fruit upou a tomato fruit or a cucumber upon another cucumber. This 

 work is still under progress, and it promises some interesting results in a new and 

 unexpected direction, reports of which may be expected later. 



The influence of depth of transplanting upon the head- 

 ing OF CABBAGES, L. H. Bailey, M. S. (p. 178).— Brief notes on an 

 experiment in 1890 iu the deep and shallow planting of Early Wake- 

 held cabbages. 



"Shallow i)lanting gave better results than deep planting, both iu 

 the percentage of good heads and iu the weight of heads. Iu 1881), iu 

 a larger experiment [with 13 varieties, reported in Bulletin No. 15 of the 

 station and Experiment Station Kecord, Vol. I, p. 283], the comparative 

 results of the two methods were indifferent. We feel, therefore, that the 

 common notion that deep transplanting is essential to success in cabbage 

 growing is at least doubtful."
