fall like the pasnip and salsify bed. Lettuce comes soon after 

 from cold frame — then from outside planting. I expect head let- 

 tuce for June and July. There are always reserve plantings of 

 leaf lettuce and radishes into July, also curled cress, sorrel, chives 

 and horesradish. Cucumbers and sweet peppers are ready for 

 August. I plant lettuce for September the last of June and for 

 October early in July. I thin these plantings instead of trans- 

 planting, as the weather is usually very trying. The October 

 lettuce must be covered with a frame when frost comes — and 

 kept aired — perhaps frame removed for a few days when weather 

 becomes warmer. Endive for November needs a frame also. 

 This is taken up and placed — roots on root cellar floor — or on 

 flats with protection of earth or sand where needed. It should 

 blanch well here. 



For December there is Celery, and I plan to have Witloof 

 chicory in January, (taken from outside in October or early 

 November and trimmed and planted close in boxes,) or perhaps 

 celery cabbage would be better. 



For February, beets — probably best put up in sealed jars — 

 but good uncooked ones are all right. 



I plan to use tomatoes and onions each one day a week for 

 extra vegetable, pot herb once or twice and beans once in place 

 of meat. 



My vegetable garden is 100x65 feet, including walks. Sweet 

 herbs border one walk, and asparagus frames garden on three 

 sides. 



Poisoning of Trees By Illuminating Gas. — Illuminating gas is very 

 poisonous to plants of all kinds. Trees in lawn and on the street parking 

 are the principal sufferers. The gas from leaky pipes, in the ground, fre- 

 quently causes the death of shade trees. The ground becomes more or less 

 saturated with the gas. The symptoms of gas poisoning are not always 

 easily distinguished from those of other troubles. Usually the first symptom 

 of gas poisoning in the summer is that of the leaves turning yellow and 

 dropping, the upper part of the tree showing the effects first. Dead limbs 

 appear here and there and the roots and sapwood at the lower part of the 

 tree to assume a bluish color, a*nd have a peculiar, disagreeable odor. 



As a rule, the odor of gas from a leaky pipe can be detected by making 

 a hole several feet deep in the soil near the tree. If the leak is detected soon 

 enough, the tree possibly may be saved by immediate repair of the leak and 

 a thorough stirring up and airing of the soil. As a rule, however, poisoning 

 has proceeded too far before the effects are noticeable, and as the injury 

 occurs below the ground surface, no satisfactory remedies can be applied. —
