the graft is in the open, the wounds are thoroughly 

 waxed; but in the house they may be covered merely 

 with moss. This style of union is used with herbaceous 

 plants, as well as on hard wood. Sometimes the stock 

 is severed at tne point of 

 union, as in Fig. 1696; but in 

 other cases it is not severed 

 nor headed back until the cion 

 has taken hold (Fig. 1697). 

 In the latter case, the stock 

 is not injured in case the 

 graft does not grow. 



Writing of the propagation 

 of the tea plant under glass 

 (which is suggestive for other 

 plants in houses), Oliver says: 

 "Seedling stocks may be 

 grown in 4- or 5-inch pots 

 for the reception of cions by 

 the veneer method of graft- 

 ing. To have the plants in 

 perfect condition for work- 

 ing, it is necessary that they 

 be grown from the seedling 

 stage without a check, as the 

 healthier the plant the better 

 the chance of a successful 

 union. Another important 

 matter in this connection is that the stock plants 

 should not be allowed to form matted roots in small 

 pots; therefore, it will be found better to lift them 

 from the nursery and put them in pots previous to 

 the operation: or they may be grown and grafted 

 while in garden flats. If this last-named method is 

 chosen the plants should be situated far enough 

 apart in the flats to be easily handled. If the grafting 

 is performed while the stocks are in active growth, 

 the union will take place more quickly than when the 

 plants are in a dormant condition. The operation 

 should be performed in the early part of spring. Fig. 

 1698 shows how the incision in the stem should be pre- 

 pared. This should be made with a sharp knife and the 

 cut at the deepest part should not be more than one- 

 third of the diameter of the stem. The cion must be 



shaped at the 

 base so that it 

 will fit neatly 

 into the place 

 prepared for it 

 on the stock. 

 It should then 

 ^ be tied, and 

 afterward a 

 small quantity of sphag- 

 num moss should be tied 

 over the part where the 

 stock and cion come 

 together. Immediately 

 after the operation is 

 performed as above de- 

 scribed, the plants 

 should be placed in a 

 close shaded propagat- 

 ing-frame and kept there 

 until the union is 

 effected; this will take 

 place in a few weeks. The tem- 

 perature of the frame should 

 then be kept uniformly at 60 

 to 65 F. If a layer of moss 

 be put under the pots and the 

 contents of the frame syringed 

 occasionally a favorably 

 humid atmosphere will result.

for the propagating-frame a hotbed may be built out- 

 of-doors in a location where the sun will not have much 

 effect in raising the temperature. From 6 to 9 inches of 

 stable Utter and leaves will provide ample heat during 

 the spring. When it is found that the cions have made 

 connection with the stocks, air should gradually be

admitted to the frames. Shortly after this the tops of 

 the stocks may be cut off close to the cions. Planting 

 out may be deferred till the cions have made their 

 first growth." 



A form of veneer-graft is what is sometimes called 

 the side-graft. It is shown in Fig. 1699 (adapted from 

 Oliver). 



Cion-budding. 



When a woody cion is inserted underneath the bark 

 in the side of the stock, as a shield-bud is inserted, the 

 method is sometimes' known as cion-budding. In 

 describing a simple way of propagating the fig, Oliver 

 writes: "This method consists of preparing the stock 

 for the reception of the cion as in shield-budding. This 

 is done by making a transverse cut through the bark

% inch in length. From the middle of this incision 

 another cut is made toward the main stem or root for 

 fully an inch. The bark is then pried up as seen in 

 Fig. 1700. Instead of inserting a single shield-bud, a 

 small twig having one terminal and one or two lateral 

 buds is used. The cion is prepared as follows: A long 

 scarf is made at one side through the pith and a thin 

 piece of the bark on the reverse side is removed. With
