220 MANUAL OF MODEEN VITICULTUEE. 



The following varieties were used as scions : 



11. Zinfandel, from J. K. Moffit, St. Helena. 



12. Mondeuse, from J. K. Moffit, St. Helena. 



13. Tokay, from John Swett and Son, Martinez. 



14. Ferrara, from John Swett and Son, Martinez. 



The following varieties were used for rooting experi- 

 ments : 



15. Rupestris du Lot, from Beringer Bros., St. Helena. 



16. Riparia Gloire de Montpellier, from John Swett and Son r 



Martinez. 



17. Solonis, from John Swett and Son, Martinez. 



The main objects of this series of experiments were to 

 ascertain the relative value of: 



(a) The English graft and the Champin graft. 



(b) Leaving two eyes on the scions, and leaving only one. 



(c) Preliminary callusing in sand, and planting out in 



the nursery immediately after grafting. 



(d) Callusing in sand alone, and in straw covered with 



sand. 



(e) Rupestris du Lot, Riparia Gloire de Mont- 



pellier, Lenoir, Herbemont, Cunningham, and 

 American Ruldnder as regards root formation 

 when bench-gral'ted. 



(f) Rupestris du Lot, Riparia, Gloire de Mont- 



pellier, and Solonis as regards rooting when not 

 grafted. 



Light was thrown on other points, such as the possibility 

 of grafting successfully various varieties of different habh% 

 such as the small-growing Zinfandel and the large-growing 

 Ferrara, upon Rupestris du Lot. 



GEAFTING. 



Preparation of Cuttings for Grafting. The Rupestris 

 du Lot cuttings used for grafting stock were in excellent 

 condition at the beginning of the grafting season, as they 

 were kept under cover in moist sand during the winter. The 

 cuttings were less than 2 feet long, rather short jointed, and 

 generally too thick at the lower end and too thin at the 

 upper for grafting. This was doubtless due to the dry 

 summer, which resulted in a short growth, and it was rarely 

 possible to obtain more than one graft from a cutting. The 

 sizes used for grafting varied from % to J- inch in diameter. 

 The thin tips which could not be used for grafting were put 

 out in the nursery for rooting.
