 sodium fiourid. a L s1i1. : Up to this time the demand 5 for the material has been very
 limited. Its former use has been
 against cockroaches, for which : 1t has been very effective. Ow- ing to this limited demand the material is not ordinarily to be found in local durg stores. | The Grand Canyon Drug store has ordered supply which will be on hand very soon.

 APPLICATION
 In treating poultry with SO dium f1ourid, if proper methods are followed, remarkable de- gree of control is obtained. One application will completely de stroy all lice present if all of the fowls on the premises are treated.
 Sodium fourid may be ap- piled in two forms as a dust and as dip. :,
 The action of sodium fourid when applied in dust form, IS lcomparatively slow; hence, ii fowls are examined even two or three days later, some lice may be found. The material per- sists, however, and after tour or five days all lice disappear.
 For complete -destruetion ofi lice it is essential tosplace small amounts of the materials on diff ferent parts of the birds. Con- trary to the usual belief, all spe- cies of lice do not migrate free l ly from one pare of the bird to another, hence the material must be we'll distributed.
 !, The pinch method is entirely effective. The fowl is placed on a table and is held by the legs or wings with one hand while with the other hand small pinch of the chemical is placed among the feathers next to the skin about as follows: : One pinch on the head, one on the neck, two on the back, one on the breast, one below the vent, one on the tail, one on either thigh, and one scattered on the underside of each wing when spread. Each pinch can be: distributed somewhat by pushing the thumb and fingers among the feathers as the ma terial is released. It is advis- able when dusting to hold the chicken over a large shallow pan, as in this way the small amount of material ordinarily lost is recovered.
 The material may be applied by means of a shaker, but this method has some disadvan- lltages as compared with the pinch method. When this method (shaker) is used the amount of sodium fuorid used may be reduced by adding four parts of road dust or flour to each part of chemi- cal. If the material is used al- one more of it is used than by the pinch method, and dust floats in the air, which causes | irritation of the throat and nose. This can be avoided if the operators wear dust guards or keep pieces of wet cloth over the nose and mouth.
 For lice on young chikens, in fact all newly matched fowls, the application of sodium four ir in dust form is recommended rather than by dipping. 5a 9s DIPPING I3'7 "iS'1 X
 There seems to be a general sentiment among poultry rais- CTS against dipping of fowls. This is probably partially on laccount of the factthat the dips tried have tended to soil the I feathers and in sonie cases in iure the skin of the fowl and give the feathers a thoro wet ting. This aversion is not justi- flied when dipping in sodium 1 fourid. The first requisite is a warm, sunny day. Windy I weather should be avoided. If the operation is finished anhour
