and the severity of the infestation, the spray being a little
quicker in its action, particularly in unfavorable weather, than
the dust.
 Of the compounds of sulphur, lime-sulphur is one of the
 best. Use about 1 gallon to 70 gallons of water. Use either
 the commercial product, or mix 8 pounds of lime and 8 pounds
 of sulphur. Cover the lime with about 6 quarts of water, and
 as the mixture becomes heated, add the sulphur slowly. When
 the slaking is over, quickly cool the mass by pouring cold water
 into it.
 A compound that will act quickly and can usually be bought
 at drug stores is potassium sulphide (liver of sulphur). One
 pound of this to 50 gal-
 B lons of water will prove
 Satisfactory, especially if
 from 2 to 5 pounds of
 Y fflour are added.

 beans. It is closely re-
 lated to that species and the treatment of infested seeds is the
 same. (See bean-weevil, page 132.)
 Other pests of peas are: Onion root-maggot (see under
 onions, page 173) ; and plant-bugs (see under potatoes, page 177,
 and pumpkin bug under cowpeas, page 161). The bugs attack
 chiefly the young pods.

 PEPPER
 The insect pests common to the pepper are: Garden aphid
 (see plant-lice, page 144) ; flea-beetles (see page 136) ; pumpkin-
 bug (see page 161); leaf-footed plant-bug (see page 178); flea-
 hopper (see page 162) ; and blister beetles (see page 134).

 POTATOES
 BIG-FOOTED PLANT-BUG (Acanthocephala femorata)
 This big brown bug (fig. 100) with club-shaped leg-joints is
quite common on early potatoes especially when planted near
hammocks, in which they hibernate. It is by far the -largest
