It is probable that the insect com monly known as the "13-year-lo- cust" will be a visitor in Pine Bluff and vicinity this year, and it is cer- tain, unless the customs of the in- sect have recently changed, that they will be found over large portion of Arkansas, and particu- karly in the northern part. Arkan- sas will not alone be visited by the insects. Parts of several other states will be troubled in the same way.
 Dr. c. F. Adams, professor of entomology, and state inspector of the University of Arkansas, was asked about the matter and gave out the following interview:
 ""This is to be locust year. The brood which will come out this year is one of the largest of the 13-year variety, and is probably the best known. Entomologists have been acquainted with it since 1903, and intimately so since 1868. lit is technically known as the tredecim race of Cicada septencedim, and fa- miliarly as the periodical cicada.' The term locust is misapplied here. The insect will appear over the larger part of the state, but it will honor more especially the northern half of Arkansas. The northern part of this state, most of Missouri and the southern half of Illinois together will be the stage whereon this interesting creature will act out the last year of it's pe- culiar life. The remainder of Ar kansas, parts of Louisiana, Ken lucky, Tennessee, Mississippi, Ala bama, Georgia, the Carolinas and Virginia will also come in for a share of this insects attention.
 The Life of the Pest.
 ''As is usually the case in popu- lar entomology, there are many and varied stories and opinions relative to this insect. As matter of fact. though, it's life, history is rather simple. differing from others prin- cipally in length of time. The adult. 1 insect lays it's eggs on the younger branches and twigs of trees. These in turn hateh and the young drop 1 to the groInd, where they take up I a subterranean life. Here they spend 1 the greater part of the 13 or r years, as the case might be. During l this time they mott, or shed their skin, four times, the last time en- tering the so-called pupal stage. Af- ter reaching the pupal condition the insects come to the surface of the ground, crawl up tree and trans l form to the adult stage. Not hav- I ing basked in the limelight before, and probably fearing they might lose this opportunity, they immedi- ately make a great noise
 Extinction of Pest at Hand.
 Probably the most interesting feat ure of this insect is the origin and number of the different broods. It is probable that in former times the pe- riodical cicada was represented by single brood, which appeared in diff ferent parts of the country at about the same time. In the course of ages, however, geographic and climatic changes caused the original brood to become broken up into smaller ones, with different dates of appearance, but with different lengths of life. So great is this difference that in two cases two distinct species are sup posed to exist. Be that as it may, this insect is listed for an early (com- paratively speaking,) extinction. And this might be another reason for its great noise, not as farewell song but an effort to secure dominance.
