OCTOBER: FIRST WEEK 257 



must have the factors for success, of which water is, of 

 course, a vitally important one, well under control. At the 

 same time, it is just as well for you to realize that the returns 

 from it on the basis of the amount of space allotted to it 

 will be much higher than from any other part of your gar- 

 den. For instance, outdoors you set your rows of lettuce 

 twelve to fifteen inches apart and set out the heads or thin 

 them to about twelve inches. In the cold-frames fifty heads 

 are set to a space three by six feet (eight inches each way) , 

 from which space outside you would get eighteen or twenty 

 heads. 



Three Kinds of Sash 



The equipment for intensive gardening of this sort is a 

 httle more diversified, but on the whole much less expensive 

 than ordinarily supposed. You are probably familiar with 

 the ordinary cold-frame — a box or frame with sides of wood 

 covered with a standard glass sash (size three by six feet), 

 and provided with a wooden shutter or a straw mat for 

 covering in extreme cold weather. The eqmpment which I 

 am going to recommend contains sash of three distinct 

 sorts, each of the three especially valuable for its special use. 

 In the first place, there are the double Hght sash; these cost 

 a little more than the others, for they are made with a 

 double layer of glass with an air space between them which, 

 being an efficient non-conductor, answers the purpose of the 

 mat or shutter in keeping out the cold, but with this great 

 advantage, that at the same time it will let all the sunshine 

 in. The double Hght sash is a distinct and valuable im- 

 provement in the way of garden equipment, and is proving 

 wonderfully valuable to thousands of places. But it is when 

 used to supplement sash of the ordinary kind rather than 

 to take the place of them, that one gets the greatest amount 

 of service from them. Because with the double light sash, 

 where one has no greenhouse, seeds may b6 sown and the 

 plants started and grown to a size large enough to transplant 

 to the frame under the regular sash at a season when, under 

 the old methods, you would just be starting them.
