ment among them. Great care should also be taken to prevent worms 

 from finding their way into the pots, as these soon choke up the drain- 

 age. Should any find their way in, however, the best way to get rid 

 of them will be to fill up the hole in the bottom with clay, and then 

 fill the pot up with clear lime-water. This can be easily made by 

 putting a few hot shells in a tub of water, and letting it stand for 

 twenty-four hours or so before using. The clear water only should be 

 used, and this will soon cause the worms to come to the surface, when 

 they can be picked off. The pot may be allowed to stand for a 

 few hours, when the clay should be removed and the water allowed 

 to drain off. It will not harm the plant, but is certain death to the 

 worms. The Genetyllis is a native of the Swan River. The soil best 

 suited to its requirements consists of good peat and turfy loam, two- 

 thirds of the former to one-third of the latter, and sufficient sand to 

 keep all open. They are increased by cuttings of the half-ripened 

 shoots, put in silver sand in the ordinary way under a bell-glass. Pot 

 them off singly when rooted; pinch them when young to get them into 

 shape, and the after-treatment will consist of shifting them when they 

 require it, training them into the shape desired, and general w^atch- 

 fulness that they do not suffer for want of water, nor be afilicted by 

 getting too much of it. J. G., W.

Medium Trees on Medium Walls. — For walls which are only 8 or 10 

 feet high, we think what we have already called medium trees are 

 most suitable. Trees on free stocks, especially where the soil is good 

 and deep, are apt to produce too much wood to be fruitful when 

 unduly restricted in growth, unless this restriction is caused by sys- 

 tematic root -pruning and root -lifting. It is better to attain the 

 desired conditions of restricted growth by having the trees on Para- 

 dise stocks. The Paradise requires much less root-pruning to induce 

 the roots to become fibry and keep near the surface than the seedling 

 Apple or even the Crab, and hence its desirability for medium-sized 

 trees. 



Either fan or horizontal training may be followed, as in the case of 

 large trees — but we certainly prefer fan-training. In either case the 

 treatment required is just the same as with large trees. Pinching, 

 pruning, and root-pruning should also be done on the very same j^rin- 

 ciple and in the same way as we advised for trees in the open. If the 

 directions given for medium trees in the open quarters are studied, 

 along with the directions for training and otherwise treating large 

 trees on walls, no need will be required to particularise the details of 

 cultivating these smaller trees on walls.
