within one bud of their base ; from 

 the bud left a flowering shoot will 

 generally be developed next season, 

 or it may be another strong shoot, 

 which may be useful, though not 

 wanted the previous year ; in which 

 case keep it ; if not, either pinch it 

 back, and cause it to form a mass of 

 laterals, or leave it to grow its full 

 length, and then cut it back as before. 

 Two more remarks seem needful to 

 complete these directions. By train- 

 ing the leading shoots straight up the 

 pillars they will grow with more 

 vigour ; by training them regularly 

 round and round the pole, the growth 

 will be more moderate and regular, 

 and there will be an earlier disposi- 

 tion to form flowering wood. I pre- 

 fer in all cases to allow new shoots to 

 go straight up, and to twist them the 

 next season, after pruning. This 

 secures strong wood in the hrst year, 

 and plenty of laterals in the second. 

 The last remark is, that poles and 

 pillars should not exceed twelve feet ; 

 and when it is determined to have 

 them of that height, the most robust- 

 growing pillar roses should be se- 

 lected. The better kinds of hybrid 

 perpetuals and Bourbons do best on 

 pillars of six to eight feet ; if taken 

 higher, it is difficult to keep them 

 furnished at bottom. 



We may now offer a few remarks 

 as to the poles and pillars themselves. 

 It is best not to insert these till the 

 roses have grown two years, and 

 when inserted, it must be in a way to 

 stand iirm during a gale. Larch 

 poles, with short snags, and the 

 bulky portion of the roots attached, 

 make the best of pillars, as when 

 planted they have a firm hold of the 

 soil, and are not easily blown out of 

 the perpendicular. Old stems of yew 

 are very durable ; ash poles require 



frequent renewal, and being slight, it 

 is best to put two or three close 

 together, and brace them together 

 with copper or galvanized wire, so as 

 to form one stout pillar. In all cases, 

 it is best if the lower parts of the 

 posts can be charred, as this prevents 

 the growth of mycelium, by which so 

 many roses are destroyed, owing to 

 the proximity of decaying wood to 

 their roots. 



When climbing roses are used 

 conjointly with genuine pillar roses, 

 very beautiful effects may be pro- 

 duced. The climbers may be trained 

 as fast as they will grow, without any 

 pruning, to cover the roof of a temple, 

 and the pillar roses trained to the 

 trellis supports, which by a regular 

 course of pruning they may be made 

 to cover completely. To form a 

 simple rose temple is a matter of no 

 great difficulty, as suitable breadths of 

 stout galvanized wire trellis can be 

 obtained at a cheap rate, and the roof 

 might be either of zinc or copper, or 

 left open by continuing the breadth 

 of trellis in a graceful curve to the 

 apex. There can be nothing more 

 suitable for the centre of a rosarium; 

 and, besides its elegance as an archi- 

 tectural object, it serves the useful 

 purpose of displaying varieties that 

 are only seen to advantage when 

 allowed to grow to vast dimensions. 

 Other and more simple methods of 

 training will occur to the ingenious 

 rosarian, as, for instance, a tall pole 

 sustained by trellises, chains, or wire 

 ropes, in the fashion of a flagstaff. 

 The pole may be covered with a climb- 

 ing rose, or with ivy, the dark green 

 of which would show up the roses 

 trained to the chains very effectually. 

 An open tent, formed of roses trained 

 to trellises, forms an agreeable rendez- 

 vous in summer time. 



THE COMMON POLYPODY. 



Polypodium vulgare, Linnseus, 

 Babmgton, Leakins, Moore. Ctenop- 

 ieris vulgaris, Newman. Fronds 

 deeply pumatifid, linear oblong or 

 ovate oblong, acuminate; lobes linear 



oblong, obtuse or acute, obscurely 

 serrate, connivent. 



The common Polypody is the most 

 widely distributed and the best known 

 of all the British ferns, and when in
