II H A hundred limes n dsy on in average Hj the qucfitlon It asked by visitors t the ftQ building of the Untied States Fish BH OunimlMloa, How In the world I It BV possible to tell with any drgrco of H accuracy how many eggs aro placed In Hl any given shipment or are usually BBj kept? And the questioner la generally BBJ much surprised when he la Informed Bj that by means of a scale ilovlsod by BVJ one of the attachm of the commlmlon Hj It la possible to tell to a nicely Just Hj what la dealreil to be known on the- H subject, whether It bo concerning the M rggs of the Spanish mackerel, which H aro o amatl that a standard United BBJ Htalc quart measuro of 67.7G cubic BBJ Inches will contain 1.2G7.728, or of BBJ land-lorked salmon, 3,300 eggs of BBJ which will fill a similar measure. Tho BBJ measuring scale la a IlKht square made BBJ of wood, not so liable to break the Jar BBJ as metal The long leg of the square BBJ la fifteen Inches long, half an Inch BBJ wide and quarter of an Inch thick BBJ The abort leg la of the aatno breadth BBJ nnd thickness and half the length, Tho BBJ long leg la graduated to rend from BBJ the bottom upward, The (Inst grade Is BBJ at n height corresponding to the level BBJ attained In the Jir by a measured half BBJ pint of water, the surcecdlng gradea BBJ aro determined by the Introduction of BBJ additional half pints of water All BBJ rneaaurementa are mado with a feed BBJ lube In place, the water abut off nnd BBJ the egga allowed to thoroughly settle. BBJ The short leg of the square la placed BBJ over the top of the Jar, the long leg BBJ hanging down, and the scale read from lh point where the top layer of egr bows In the Jar. It Is possible to obtain ob-tain by measurement an almost correct rntlmatn of the number of fish produced pro-duced by a Jar of semi-buoyant eggs. Just before the time of hatching all dead eggs are carefully drawn off. It 1 an ascertained fact that scarcity any semi-buoyant egga die under proper conditions niter hatching out haa commenced com-menced In connection with the scale there Is used a Jar whl'h presents as easy, quick and safe means of ascertaining ascer-taining the knowledge sought. The measurements In all eases are mads while the eggs are In the Jar, and with the cap screwed down How to ascertain ascer-tain tho number of eggs lost or hatahsd or aro on hand Is n question constantly con-stantly arising It would be cumbersome cumber-some and tedious were It compulsory to open a Jar and measure the eggs In n graduato every time such Information Informa-tion was needed, The question of measuring tho eggs la a most Important Impor-tant one to the fish uilturlst, and yet. to Judge from tho various waya of measuring eggs. It la one that haa received re-ceived little attention. Kvcry branch of trade has a standard measure, but flah culture has remained without standard stan-dard or rational unit, each workman establishing for himself n ayatem of determination and varying that ayatem from year to year, as the eslgcncles of the aeaaon demanded There haa not only been a want of harmony In tho vnrlous so-called measures used, but the measures themselves have lacked tho elements of reliability, being be-ing In many cases tho most arbitrary nnd Irratlonnl, The records of results of work In tho earlier days of fish culture wcra but wild guessing, nnd, sad to say, many records are yet mad In tho same manner. The practice of arriving nt the number of any given lot of eggs by estimating each parent Ash to contain on unvarying quantity of eggs and multiplying this quantity by (lie number of females spawned has Justly gone out of existence.
