sown after the soil is dug for its recep- 

 tion, the earlier it germinates. In the 

 droughts of summer, water is often re- 

 quired to newly-sown beds. Such ap- 

 plication must not be very limited or 

 transitory ; for if the soil is only moist- 

 ened at the immediate time of sowing, 

 it induces the projection of the radicle, 

 which in very parching weather, and 

 in clayey, caking soil, I have known 

 wither away, and the crop be conse- 

 quently lost from the want of a con- 



brids, are the next in beauty to G. 

 psittacinvs, but they are not so hardy 

 nor so vigorous. They require taking 

 up every season ; for if left in the 

 ground, though protected with a cover- 

 ing, they always sufler from damp, and 

 never start early enough to flower well 

 the next season. 



" About the beginning of October, 

 to propagate them, take from well- 

 established plants a cluster of corms 

 about one and a half or two feet in cir- 



tinued supply of moisture. — Princ. of cumference, and plant them one foot 



apart, and two or three inches deep, in 

 beds two feet wide, with a little sand 

 at the bottom of the bulbs. When 

 forced, this plant forms a brilliant orna- 

 ment for the green-house in the begin- 

 ning of summer. 



" In the month of October take eight 

 or twelve-sized pots, and fill them with 

 as large a mass of the strongest corms 

 as the pots will admit, and protect them 

 till they are required for forcing." — 

 Gard. i'hron. 



" Gladiolus psittacinus or natalentis, 

 is one of the most ornamental of the 

 Cape gladioli, and, from its easy culti- 

 vation, deserves to have a place in all 

 flower-gardens where a brilliant dis- 

 play is required during the autumn. 

 Beds should be prepared some time 

 during the winter, or early in the 

 spring, by digging up the soil deep 

 and leaving it rough, adding, at the 

 same time, a good portion of well- 

 rotted dung and a little sand, if the soil 

 is of a stiff nature ; but if light, sand ia 

 not required. 



" About the middle of April mark 

 out the bed into rows, one foot apart 

 and four inches deep, putting a little 

 sand along the bottom of the rows ; 

 then place the bulbs in the rows, about 

 nine inches or one foot apart, taking 

 care to separate all the bulbs, and only 

 plant one in each place; then, having 

 a little sand (any refuse from cutting 

 pots, or bank-sand, will do), put a 

 small portion round each bulb, and fill 

 in the rows. After this the plants will 

 require no further trouble excp[)t keep- 

 ing clean and tying up, which latter is 

 easily done by driving a few sticks 

 round the outside of the bed, and run- 

 ning a couple of tiers of tar-twine round 

 it. With this treatment the gladioli 

 will begin flowering about the end ot 

 July, and will contmue blooming for 

 nearly two months, particularly if they

GIRDLING is a mode of killing 

 trees adopted in clearing the forests of 

 America, by cutting, early in the 

 spring, a girdle or ring round the stem 

 of each tree, taking away not only the 

 bark but the entire alburnum down to 

 the hard wood — the ascent of the sap 

 is thus prevented. See Ringing. 



GLADIOLUS. Forty species ; many 

 varieties. Chiefly green-house, and a
