 SIDE HILL HOUSES. 



Some years ago it was the custom to build a greenhouse on a side hill, using the 

 side of the hill as one side and having the glass run on a gradual slope to the bottom 

 of the hill. These were thought to be excellent houses, this probably being that one 

 side of glass was saved and that the house was always free from heavy wind storms, 

 etc., owing to its peculiar location. Of recent years this idea has been entirely 

 changed, and the side Jiill houses are practically a thing of the past. Growers now 

 demand light on both sides of the roof and also demand good side ventilation. This 

 cannot be had with ordinary side hill houses. Another objectionable feature of 

 houses built on the hill side is that the beds or benches all must be on different 

 levels as one goes down the hill. This entails extra labor and prohibits the possib- 

 ility of horse cultivation. There are those who stick to the side hill house, but they 

 are a very small minority, and the general opinion of growers is that the upright 

 two sided greenhouse is what is required. Some men have ideal locations for 

 greenhouses of the hill slope style but refrain from building, because they realize 

 that they are money in pocket by paying for increased ventilation and the decrease 

 of labor cost. 



VENTILATION. 



Ventilation of the greenhouse is a necessity for the growing of any crop. Too 

 much attention cannot be given this part of construction, and the most approved

Side ventilation is necessary in large plants. Continuous runs of ventilator are usually 

 located at the eave or lower. Usually made to open out, but some have them open- 

 ing both in and out. 



arrangements and forms of ventilating apparatus should be carefully inspected 

 before the installation of any. Ventilators are now being used on both sides of the 

 house and in continuous runs, both sides of the ridge, and also in continuous runs, 

 or in broken or alternate runs. Gable end vents are also being advocated and used 

 by some progressive growers. These are not common as yet, but some men claim to 

 have had a marked degree of success with them. They are arranged in different 

 ways and as yet seem to be more the ideas of individual growers.
