CROPS UNDER GLASS 



63 



areas of glass. Suppose a man should start in with a house 

 forty feet wide and one hundred feet long, placing it in such 

 a way that he could add to it lengthwise, and build other 

 houses beside it. A man with that area would have a little 

 bit of difficulty in securing a perfectly continuous supply, and 

 yet I believe by careful management, he could accomplish it 

 and build up by an occasional trip a pretty fair trade. 



Mr. Wrigley : We ship about half what we raise to Waver- 

 ly, Corning and Williamsport. 



Mr. Work: This illustrates the case, for Mr. Wrigley has 

 not a very large plant, about three-quarters of an acre. That 

 means about thirty thousand square feet. Such a house as 

 I mentioned, forty by one hundred, would be four thousand 

 square feet. Do you make it a point to have your different 

 crops of lettuce in different houses? 



Mr. Wrigley : Our trade is so great that we pull a bed out 

 and reset at once — small lettuce and large in the same house. 



Mr. Work: You think it is better to have your different 

 strains in different houses, do you not, Mr. Zuck? 



Mr. Zuck : We begin in the fall and plant right over our 

 area, so that we have our houses full by the time the first 

 planting is ready to cut and keep going right around all the 

 time; but if we are cutting in a certain house and have too 

 much, we can cool that house off and hold it. There may be 

 some small lettuce in it just planted. 



Mr. Work: It does not ordinarily happen that you have 

 big lettuce and little lettuce in the same house. How about 

 your continuous supply, Mr. Hunter? 



Mr. Hunter: We do not pay any attentfon to that. If 

 we have a plot vacant, we set it. 



Mr. Work: How much glass have you? 



Mr. Hunter: About three thousand square feet. 



Mr. Work: And you say you are able to have it almost 

 continuously? 



Mr. Hunter: Yes.
