Cobb Miniature Greenhouses 
“Traps to Catch the Sunbeams” 
These successors to the cold frame are made of glass. They are practically ever- 
lasting in use as they are strong, rigid and portable. Seeds may be sown up to five 
weeks earlier and crops are advanced accordingly—all-year-round gardening at last 
becomes possible. Pansies, strawberries and small spring flowering bulbs covered dur- 
ing the coldest days with these miniature greenhouses are completely protected from 
wind, rain and frost, giving proper ventilation without constant manipulation during the 
winter. Use them for growing cuttings and early lettuce and parsley. The risk of vege- 
table and flower seeds rotting in the ground or being eaten by pests is eliminated when 
protected with these sets. They come in two patterns—tent type, 10” by 14”, 65c unit; 
barn type, 12” by 18”, $2.00 unit. Write for circular giving further particulars and uses.

used to be necessary for each class. Now ‘’Green-Tox” kills both. It is a contact poison to 
sucking insects, and both contact and stomach poison to chewing insects; yet it is harmless 
to humans and domestic animals. ‘‘“Green-Tox" not only kills insects, but likewise repels them. 
Foliage sprayed with ‘’Green-Tox’’ remains toxic to insects for many days and prevents 
reinfestation. No need to worry about insect damage when plants are sprayed with ‘'Green- 
Tox.” It takes the ““guess’’ work out of spraying.
