CHAPTER XVI 

 PLANS AND ESTIMATES 



The cost of any kind of a building must 

 necessarily vary with the cost of building 

 material and the price of labor. This is es- 

 pecially true with greenhouses, since the ma- 

 terials used (glass especially) are subject 

 to extreme fluctuations in price. In the pre- 

 ceding chapters it has been the aim to give 

 all the data necessary for estimating the 

 amount of material required for any given 

 house, but no attempt has been made to state 

 definite prices. 



Little can be added in this chapter to what 

 has already been given, and it would be use- 

 less repetition to collect the data into one 

 chapter, as it may be easily found by refer- 

 ring to the index. An effort has been made, 

 however, to make some suggestions as to the 

 probable cost of different types of houses un- 

 der varying conditions.
