PUT 



PYB 



Sow in drills six inches apart, very 

 thin, and not more thr.n a quarter of an 

 inch deep. Keep the seedlings clear of 

 weeds, and thin to six or eight inches 

 asunder. In dry weather water mode- 

 rately two or three times a week. 



In general, they are ready for gather- 

 ing from in six weeks after sowing, the 

 youBg shoots heing made use of from two 

 to five inches in length, and the plants 

 "branch out again. 



The hotbed crops require the air to be 

 admitted as freely as the weather per- 

 mits, the temperature ranging between 

 50 and 75. 



To obtain Seed. A few of the earliest 

 border-raised plants must be left unga- 

 thered from, the strongest and largest 

 leaved being selected. They must be cut 

 immediately the seed is ripe, laid on a 

 cloth, and when perfectly dry, thrashed, 

 and the refuse is best separated by 

 means of a very fine sieve.

 ivorts [Liliacese]. Linn., 6-Hexandria 1- 

 Monogynia. Allied to Hyacinth.) 



Half- hardy bulb. Offset-bulbs ; deep, sandy 

 loam ; requires a little protection, or to be taken 

 up in winter.

PUTTY is a compound of boiled linseed- 

 oil and whiting, but as it may be bought 

 in London at Italf-a-guinea per cwt., it is 

 scarcely worth while to make it. One 

 hundred weight is enough for puttying 

 about three hundred square feet of glass. 



Old putty may be softened by applying 

 to it rags dipped in a saturated solution 

 of caustic potash, leaving them on for 

 twelve hours ; cr by rubbing a hot iron 

 along the putty. 



If the gardener does make putty, the 

 whiting should be well dried, and then 

 pounded and sifted till it becomes a fine 

 powder, and is quite free from grit. The 

 whiting, a little warm, should be gradu- 

 ally added to the oil, and well-mixed by 

 means of a piece of stick, or a spatula. 

 'When it is sufficiently stiff, it should be 

 well worked with the hand on a table, 

 and afterwards beaten on a stone with a 

 wooden mallet till it becomes a soft, 

 smooth, tenacious mass. A ball of putty, 

 when left some days, becomes somewhat 

 hard, but may be easily softened by 

 beating^
