A correspondent desires to know whether the Salisburia or Ginko tree will graft at this time of the year (Jan. 19).

If the work is to be done on trees in the open air, grafting cannot be done successfully till growth has commenced. In all grafting there is danger of the graft or scion drying out, unless there is activity enough in the stock to furnish the moisture that the graft requires. It is found best in all grafting to keep the scion back a little in order that the stock may be certain to have the supply the scion requires. In winter grafting the work can be done if the stock is somewhere where the temperature is above freezing point, so that the active action of the stock be not wholly suspended.
