Sept.~] GREEN-HOUSE - OBSERVATIONS. 385

 cated li 



as large as a human head, pear-shaped, and tuni- 

 cated like the onion. From the centre of the root arise 

 several shining glaucous leaves a foot long, two inches 

 broad at base, and narrowing to a point. They are green 

 during winter, and decay in the spring ; then the flower- 

 stalk comes out, rising two feet, naked half-way, and ter- 

 minated by a pyramidal thyrse of white bowers. The bulb 

 ought to be kept dry from the end of June till now, or it 

 will not flower freely. 



GENERAL OBSERVATIONS. 



Watering, and other practical care of the plants, to be 

 done as heretofore described. Frequently the weather at 

 the end of this month becomes cool and heavy. Dew fall- 

 ing through the night, will, in part, supply the syringing 

 operation, but it must not be suspended altogether. Once 

 or twice a week will suffice. Any of the plants that are 

 plunged should be turned every week. In wet weather 

 observe that none are suffering from moisture. 



SEPTEMBER. 



DURING this month every part of the green-house should 

 have a thorough cleansing, which is too frequently neglected, 

 and many hundreds of insects left unmolested. To pre- 

 serve the wood-work in good order, give it one coat of paint 

 every year. Repair all broken glass, white-wash the whole 

 interior, giving the flues two or three coats, and cover the 

 stages with hot lime, white-wash, or oil-paint; examine 

 ropes, pulleys, and weights, finishing by washing the pave- 

 ment perfectly clean. If there have been any plants in the 

 house during summer, be sure after this cleansing that 

 they are clean also, before they are returned to their re- 

 spective situations.
