As a result of experiments with various dipping fluids for San Jose 

 scale [Aspidiotus perniciosus], details of which are described, the 

 greatest success was obtained with miscible oil at the strength of 

 1 : 12 or 1 : IvS ; only the tops, however, should be dipped, so as to 

 minimise injury to the plants. Hydrocyanic acid gas is most effective 

 when used upon dry plants at the strength of 1:1:3. Lime-sulphur 

 used at 1 : 9 gave perfect results on pears and plums, but injured the 

 plants. It is advisable to treat all nursery stock that has been sub- 

 jected to attack, even though not actually infested, before placing 

 it on the market.

This is a popular account of the life-history and control of the ever- 

 green bagworm [Thyridopteryx ephemeraeformis, Haw.] [R.A.E., A, 

 iv, 239]. This moth was very abundant in Missouri in 1919.

The existence of Pyratisla nubilalis in Missouri has not yet been 

 proved, and to prevent its spread from the eastern areas of infestation, 

 a quarantine has been promulgated prohibiting the movement of any 

 material likely to harbour this moth. Special provision is made for 

 the shipment of shelled maize.

The present Federal quarantines and other regulations affecting 

 the importation of stock from abroad and the transportation of it 

 in the United States, as well as various State laws and regulations, 

 are briefly dealt with.
