TENANT'S FIXTURES. 41 
In large and lofty conservatories, or where a very 
ornamental appearance is desired, top ventilation is frequently 
provided for in the method shown in Fig. 25. In this, 
there is what is termed a super-roof, with ventilators 
that are opened and closed by means of pulleys and cords, or 
by means of lever gearing. 
In what are termed tenant’s fixture greenhouses, the 
sides must necessarily be constructed entirely of wood, or 
wood and glass, any brickwork or concrete constituting it a 
(landlord’s) fixture. ‘‘Tenant’s fixtures,” if simply resting 
on a row of loose bricks (to keep the timbers off the soil), and 
not fixed to the ground in any way, are the property of the 
tenant, and can be removed by him at pleasure.
