is a mixture of Bandy peat, either alone or mixed with a email 

 portion of loam and lumps of sandstone, such as the soft red 

 granite of the Wicklow hills. Besides securing for them a 

 humid atmosphere, it is essential that it be still, and currents 

 of air carefully avoided. As to water, it should be quite pure, 

 and free from lime — rain water is, of course, the best. As to 

 the mode of watering, there must be no dashing or rough prac- 



tice. When grown in Wardian cases, the practice of sprinkling 

 overhead is very general ; but whether in the Fern case, or 

 the more extended field of the Filmy Fern house, the safer 

 practice is, we fancy, to eschew hand or heavy watering, and 

 let them draw their supply from the pure and compensating 

 agency of alternate evaporation and condensation. — [Irish

DRAWING PLANS. 



To transfer fig. 49 to the ground. Erect the rectangle A b c e, 

 the sides being 55 feet and 82 feet respectively. Insert stakes 

 at each point, and lay lines connecting them. Lay the diameter 

 lines E r and g h. . 

 On each side of ,, 



centre z (the point 

 where the diameter 

 lines cross each 

 other), on diameter 

 line E r, measure 

 18 feet 3 inches, and 

 insert pegs as at 

 centres a and b. 

 From the peg at 

 centre a, with a 

 string 33 feet long, 

 trace arc 1, as shown 

 by radius a 1, ter- 

 minating at points 

 g g. From the peg 

 at centre 6, with the 

 same radius, trace 

 arc 2, as shown by 

 radius 6 2, also ter- 

 minating at points 

 g g, as shown by the 

 dotted lines. From 

 the peg at point g, 

 with a string 11 feet 

 8 inches in length, 

 trace arcs as shown 

 at points e, h, f. 

 Where the arcs cut 

 arcs 1 and 2 insert 

 pegs, as at points 

 e, f. Prom the peg 

 at point g, with a 

 string 23 feet long, 

 trace arcs as in li, s ; 

 insert a peg at each 

 point. Prom the 

 peg at centre a, with 

 a string 29 feet long, 

 trace are 4, as shown 

 by radius a 4 ; re- 

 duce the string 4 feet 

 and trace arc 6 ; 

 again reduce the 

 string 4 feet and 

 trace arc 9. Prom 

 the peg at centre 

 6, with the same 

 lengths of string, 

 trace arcs 5, 7, 10, 

 corresponding with 

 arcs 4, 6, 9. On 



each side of centre z, on diameter line g h, measure 10 feet, and 

 insert a peg as at point c. From the peg at point c, with a 

 string 11 feet 6 inches long, trace arc 3, connecting arcs 4 and 

 5 ; reduce the string 4 feet and trace arc 8, connecting arcs 



Fig. 49. Scale 16 feet to the inch. 



6 and 7 ; again reduce the string 4 feet and trace arc x, con- 

 necting arcs 9 and 10. Trace the four small circles as shown ;, 

 and with a radius of 5 feet trace the arcs that cut the ends 



of the beds. Prom 

 the peg at centre a, 

 with a string 13 feet 

 4 inches long, trace 

 arc 11 ; reduce the 

 string 1 foot and 

 trace arc 12. From 

 the peg at centre d^ 

 with a string 12 feet- 

 4 inches long, trace 

 arc 23 ; reduce the 

 string 4 feet and 

 trace arc 24. From 

 the peg at centre/,, 

 with a string 12 feet 

 4 inches long, trace 

 arc 21 ; reduce the- 

 string 1 foot and 

 trace are 22. Prom 

 the peg at point g„ 

 with a string 11 feet 

 8 inches long, trace 

 arc 19 ; reduce the- 

 string 4 feet and 

 trace arc 20. Trace 

 the corresponding- 

 arcs in the same 

 manner. Find 

 centres 7i, i, J, and t ;, 

 insert a peg at each 

 centre, and from 

 their respective pegs- 

 trace arcs 25, 26, 27, 

 28 ; trace the other 

 corner beds in the 

 same manner. Di- 

 vide the distance- 

 between points i and 

 /u, as shown by the 

 dotted line, into two 

 equal parts, and from 

 the centre set ofi' 

 2 feet on each side, 

 lay lines from the 

 points thus found to- 

 the angle of the 

 figure, and lay out 

 angles e, o, b in the 

 same manner. Trace 

 circles u, v, and w„ 

 also circles t, r, and 

 X. Trace the corre- 

 sponding side in the 

 same manner. The width of the entrance walks, as shown in. 

 G H, is 4 feet. The lines and dotted parts represent Box ;■ 

 E, beds ; w, walks ; c, coloured material. — M. O'Donhell, Gar- 

 dener to E. Leeming, Esq., Spring Grove, Eiclmiond. 



THE AUSTRALIAN PEA, alias GROTTO'S MOSSY PEA. 



Some sixteen or seventeen years ago a gentleman brought 

 some Peas from Australia, which have since that time been 

 cultivated in a few private gardens under the designation of 

 the Australian Pea. Three or more years ago it got into the 

 hands of Messrs. Kennedy & Co., seedsmen, Dumfries, and 

 was last season distributed by them under the honest impres- 



sion that it was a Pea new to this country. It was, however, 

 confidently affirmed by the Messrs. Drummond, seedEmer,- 

 Stirling, to be none other than what they term Grotto's Mossy 

 Pea, which had been grown in this country fifty years ago, but 

 from some cause or another it had become scarce and little 

 known by either seedsmen or gardeners. ' We have these two
