 and the less your silo 

 costs the more it 

 pays, this is why you

 saving features and 

 sound construction, to 

 last for centuries 

 together, with reduced

 your own Silo by direct 

 labour.

' Windolite" supersedes glass for farm buildings, 

 poultry and greenhouses, frames, huts and every 

 outdoor structure. It is a specially prepared 

 transparent composition, reinforced with rustless 

 wire. Very strong and flexible, light in weight 

 yet durable, it is unaffected by weather con- 

 ditions, heat or cold, and is eminently satisfactory 

 for admitting light to buildings of all kinds, 

 requiring only the lightest of framework. It can 

 easily be cut to size with scissors, and fitted with- 

 out putty or glazing. All plants thrive under 

 " Windolite," with the use of which any handy 

 man can make light structures for protecting 

 seedlings, fruit, etc. 



Wherever glass gets broken replace it with 

 " WINDOLITE." 



If your local dealer does not stock, we will send any quantity 

 from one yard upwards, carripge paid, on receipt of remittance
