By J. O. Snyder, Stanford University. Three marked king vsalmon were secured last summer iby W. L. Scofield, who was engaged in making obeservations for the Fish and Game Commission. Each of the three specimens had the adipose and left ventral fins excised. The mutilations were of such a nature that they could not be attributed to any other causes than the methods used in marking small fish. One was taken at Monterey, April 6. It measured 73 centimeters. Along with others it was evicerated before any- thing unusual was noticed regarding the fins. The sex, therefore, could not be determined with certainty. The second was caught at Shelter Cove vsas Z CAl.IKdKMA FISH AM) (JAMK. aii(l l)i*ijii;;lit to Fiii't Hrjiii^. Aiiiiust 17.

Thi.s frayed appearance of the scales was characteristic of all fish ol)served at the time, and it plainly indicates that the absorption of reserve tissues was already in progress, a condition just preceding the breeding period. The fish from which this scale was taken was very dark in culor, and the snout had become elongated and hooked. Via. 2.

Th(^ most valiialile information eomiiio: Id iis with the capture of these marked fish is that the sea ran^e of Saei'amento salmon not onl\" embraces ^Tonterey Bay to the sotitlnvai'd. l)ut that it extends far noi'thward as well. Now thei'e is uiyently desired at the present time some definite information regarding the source of supply of the marine salmon fisheries, and we have here a very plain suggestion as to the procedure necessary to gain at least some of tliat information. To be sure, it is perfectly well known that the.se salmon breed in certain large streams. l>ut it is not known whether California streams alone contribute to our ocean supply, or whether we are in a measure reaping a harvest from seed sown north of our Ixjundaries. The opinion has been freely expressed in some (juarters tiiat the salmon of ]Monterey Bay are from the Sacramento Ki^'er. that those from Fort Bragg and Shelter Cove are from streams entering the ocean north of these lo;'alities, and in sliort. that young salmon on migrat- ing into the ocean progress southward from their place of entry, where they live and grow until the approach of maturity. With a firm belief in the theory of southward migraticn, sonu^ fishermen and others of experience will even pr(4end to identify C()luml)ia River salmon among those caught near Fort Bragg. We have at present very little to show that their l)elief is not well founded. Init they have still less to denicustrate that it is. Tin- capfui'e of this marked Sacramento River fish at Shelter Cove, a long distance north of llie mouth of the river, is then easily seen to be a matter of considei-able importance. The evidence derived from a single example should not be overestimated, however, and if simmus evidnit that only investigation involving carefully planned ex])eiiments will he of definite aid lierr and elsewhere in a profitable study of the life history of the salmon. It is very probal)le that such investigation might be carried on to better advantage in a sticani much smallci- than the Sacramento, foi" wIkmi cue comes to consider the difihculties of obtaining results from a marking experinunit. f(U^ exam])le, in a very large river with the wide distribution and varied character of its fisheries, it is really remarkable that even three fish From a i'(insi(iei'al)l(' iiuur.M'r wci-e secured. .Moreover, the (piestion as to wh(>ther some of our smaller streams nuiy l)e uuule to confi'ibute with jti-ofit to sea fishing is \\(A\ worth cniisidering. for tlie j^rescnf rapid growth of irrigatiiui and power ])r()jects. which seriously interfere with tiie natui'al i)i ceding grounds of salmon in the Sacranu'uto and Klamath I'ixci--;. foreshadows the time when some attention will be dii'ectod cls(>wliere if we seriously care to maintain our sup])ly of these lish. Thei'e is one jioint of interest connected with these scales to which. however, one is not as yet wai-i-anted in attaeiiing any real significance, ft will be ol)sei'ved that in the Shelter Co\-e scale, aiul i)art icularly ill that fi'iim flic Sacramento I\iver. the annual checks are very marked, while in the ]\fonterey specimen they ai'e much less distinct. A com- parison of a large number of scales from the region of Fort Bragg and Shelter Co\-e. with many from ^lonterey Bay. seems to give the impression that the jireseiice of sharjily defined annual checks is not very characteristic of scales of ^lonterev salmon, but that, in contrast CALIFORNIA PISH AND GAME. 5 with those from the region of Foi't Bragg, they are much less pro- nounced and in many eases diffienlt to deteet. Although one is not prepared to even speculate as to the reason for this, especially since the cause of the growth check is not known, it is, at any raie, of passing interest to observe that in the character of the growth check both the Monterey and Shelter Cove scales conform to what appears to be the fashion in each locality. And if appearances are not mis- leading, one would l)e tempted to suspect that the Sacramento fisli Fig. 3. Photomicrograph of scale of sahnon marked at the Mount Shasta.

Furthermore, if we calculate the length attained by each fish at the end of the second and third years, which may be done with some degree of accuracy from measurements obtained from the scales, it will be seen that the Shelter Cove and Pittsburg specimens agree in being smaller than the one from Monterey.

Ilei'e tliei'e ai'(» two fairly distinct migi'alions of steelhcads, one occurring in the winter, the other in the suiiuiicr. Of the winter run we know very little; nothing, in fact, of what species it is composed. The sunnnei- run consists almost entirel\- of S. irideus, an example of *S'. chirlii occasionally appearing. The latter may be spoken of as one among thousands in the migration of the former. In the summer of 191!)* the first steelhcads were taken in salmon nets on July 11: the largest number were caught al)out August 27, and the run had about ceased October 22. The progi-ess of the steelhead migration coincitled in general with that of the king salmon, not only in its rise and decline, but in its periodical irregu- * Agents of the Fish and Game Commission have been making observations on the trout and salmon for two summers in the estuary of Klamath River.

As these steelheads appear fresh from the ocean, many still bearing living salt water Crustacea attached to their bodies, they are of a beautiful deep steel blue above, with highly burnished silvery sides. They have usually very definite black spots on the head and body, they are always present on the dorsal, adipose and caudal fins, while the remaining fins are immaculate. Sometimes the head is without spots and the body has very few. Counts on a number of examples resulted as follows : Head spots, 0 to 25 ; body, 8 to 271 ; dorsal fin, 47 to 98 ; adipose, 1 to 9 ; caudal, 14 to 220. The spots of the head are almost always round; those of the body elongate or linear. The ova found in these fishes are very small, their undeveloped condition giving rise to the suggestion that the steelheads have entered upon a very long migration or at least a considerable period in fresh water. Their stomachs are mostly empty, and they remain so at least while they are in the estuary for the very simple reason that there is not food enough in the river to supply such a horde, were its members inclined to eat. They occasionally strike a spinner, but they will not rise to fly, nor are they . often attracted to a baited hook. Later in the season and farther up stream their appetites are said to return, and their behavior is governed accordingly. About the middle of August, steelheads that have begun to assume their nuptial colors are occasionally seen in the estuary. The cheeks become tinted with pink, and a broad reddish blush appears along the sides. At the same time the dark dorsal area loses its marine hue and becomes light olive. No salt water Crustacea are found attached to these tinted individuals, and it ap- pears probable that they have been in fresh water for some time. The steelheads fresh from the sea are plump, fat and full of energy. At times they have been seen in numbers leaping high from the water and falling with a resounding splash, in strong contrast to the salmon which only cut the surface with their backs and tails. The largest steelhead caught in the Klamath is said to have weighed 32 i)ounds. Those which appear from day to day are much smaller. For example, on August 13 and 14 of this year, 248 specimens that were caught in gill nets measured 14^ to 32 inches and weighed l.^r to 14-;? pounds. The entire lot gave an average weight of 5.86 pounds; 10,862 examples showed an average weight of 4.3 pounds. Small fishes are not apt to become entangled in the coarse meshes of the drifting gill nets, and it is therefore of interest to find that a fine meshed seme will bring from the river not only large specimens but smaller ones as well, individuals 8 or 10 inches in length having been taken which exhibit every detail of color possessed by the larger steelhead fresh from the sea. Whether these small fishes have just come in from the ocean we are unable at present to say. The scales of these Klamath steelheads which are identified as Salmo irideus, rainbow trout, number 116 to 150 in the lateral series. The steelhead trout taken at sea near Fort Bragg are of the same species as those that enter the Klamath in the summer in such large numbers. They may even be Klamath trout for all that we know, but it seems more reasonable to assume that their parent stream is somewhere nearer their place of capture. 12 CALIFOirXlA IMS II A.M) OAMK. THE RELATIVE MATURITY OF THE CHINOOK SALMON TAKEN IN THE OCEAN ALONG THE PACIFIC COAST.- By Wilms H. IIk ii, l-'irlil Assistant riiilrd States Buir.ui nf Fisliorics. This paper is in the nature of a preliminary report di'.iliiig with the maturity of the chinook salmon taken by troll and purse-seine in the oeean along the Paeitic eoast, and is presented for the purpose of making inniiediately available some of the results of the investigation. It is also believed that the method used for determining the relative maturity is new and may be of value to others engaged in similar in- vestigations. A later report will give in detail the data ui»()n whieh the eonclusions presented in this pa])er are based, and will discuss several topics treated very briefly, oi- omitted entirely froni this paper. The amount of trolling and purse-seining for chinook salmon along the Pacific coast has increased enormously during the past few years, especially along the northern coast of California, the coast of Oregon. and off the mouth of the Columbia River. To anyone who has observed even casually the fish thus taken in the ocean it is perfectly .appai-ent that a great proportion are innn;i1ui-e and it is a point of consideral)le interest and })ractical importance to know just wiint pei-ceiitage are immature and the relative degree of immaturity. The determination of the age by means of scale studies will not, alone, give a sufficient index to the degree of immaturity since there is such a wide range in the age at which these fish reach the spawning stage — from two to six years. If the percentages of individuals of different ages among the mature fish were constant, it would be possible, from a determi- nation of the percentages of fish of different ages taken by troll nnd purse-seine in the ocean, to estinuite the percentage of fish of different degrees of maturity. This, however, is not the case. The percentages of fish of the various age-groups vary greatly ;i1 dift'ei-ent times among the mature fish and also among those tal\en in the oeean. Pre- sumably these variations are due quite largely to racial diffi-renees bnt our present knowledge of the various races of chinook salmon is ([uite too limited to aid in segregating the races from mixed lots. Even if our knowledge of the races were com]>lete it might well be that they could not be identified and segregated accurately and fully enough to serve the purpose. It is api)arent that some other means than the determination of the age is necessary in order to leani the percentages of mature and inunature fish taken in the ocean and tlieir relative maturity. The method which has been de\eloped for determining the relative maturity is based upon variations in the size of the eggs. Obviously this can be applied only to the females and no method has yet been devised for determining the relative maturity of the males. The percentages of males and females found among the mature fish of the various age groujjs will give some basis for estimating the percentages of mature and immature males fi'oni the detei-niination of the relative maturity of the females. l)nt a discussion of this toi)ie must be i-cserved * Piil)liplic(l with the permission of the United States Commissioner of Fi.sheries.

It is sufficient to state here that, while there is a tendency for tlie iiiales to mature somewhat younger than the females, the error which would result from assuming that the pro- portions of fish of similar degrees of maturity were equal in the males and feuiales would not be serious. Superficial examination of the eggs found in the females taken in the ocean shows that there is a wide diversity in the size and, further, that several more or less distinct size-groups are distinguishable even without careful meas- urement. It is a natural assumption that these vari- ous sizes of the eggs indi- cate different degrees of maturity. A careful study of several collections of fish taken within the Columl)ia River aiul ])y troll off the mouth of the Columbia, in Monterey Bay, California, and along the northern coast of California con- firms this assumption and shows that, by means of a study of the variation in the size of the eggs and a determination of the age by means of the scales it is possible to distinguish, with certainty, in many cases, and with reasonable probability in most, be- tween fish which would have spawned during the year in which they were taken and those which would not have spawned for at least one more year. The dis- tinction between fish which would not have spawned for two years is not fjuite as definite but in some collections the interpreta- tion is clear. In studying these collections the age has been determined by the usual method of scale study. The size of the eggs has been determined by measuring ten of each sample and taking the average. The larger eggs — those over 1 mm. in diameter — were measured in a simple device 5 5th qe a r ~ stream nude i r-^~~^ S _ 4t/i i/ear- s t re ant n uc/e i ^^ 5 5th ij ear - 1 ocean nuc/e/ 1 3 4 th (jea r — ocean nuclei n Entire S - collec U '-' ^ J u [ 1 1 ^^ 0.40 .50 Logarithm of L .60 dia meter A I of 2 5 m rn. 3.0 3.5 diameter 40 4.5 or tQQS _1_ .70 J i L_ 5.0 5.5 6.0 SO Fig. 9.

In pre])aring eggs for this measurement it is neeessai-y to free them very carefully from the ovarian membranes so as not to l)roak the delicate shell and yet to clear them of all shreds of tissue which might tend to affect the measurement. The smaller eggs — those less than 1 mm. in diameter — were measured by means of a microscope fitted with an eyepiece micrometer carefully standardized.

The tabulating and plotting of these egg measurements has been done on a logarithmic basis — that is, tln' logarithms of the actual measure- ments have been tabulated rather than the measurements themselves. The main advantage of this sort of tabulation lies in the fact that proportional variations in size are ecpially shown indejiendent of the actual size, and it is the relative size of the eggs, rather than the actual diameter, which is significant.^ In preparing the tables and charts the cla.sses have been arranged with intervals of .02 in the logarithm of the diameter of the eggs. This signifies that the mid-value of each class is 4.713 per cent greater than that of the class next preceding.

Full data including scales were taken with each of the above collections. In addition to these the following two collections consisting of eggs alone were studied : 9. Eggs from 144 females taken by troll in Monterey Bay, June 29, 191.'. M). Eggs from <14 females taken by troll near Drake's Bay, August 15 aud K'). 101S, and Fort Bragg, July 17, 1918, on the coast of northern California. Scales and data were also collected from the females at the same time the collections of egg samples were made, but the records were not kept so that the egg samples could be referred to the corresponding data and scales. It has b.een necessary, therefore, to treat egg samples and other data independently. It will be impossible, in this report, to give in detail the evidence necessary to prove the validity of this method for determining the relative maturity. The graphs will, however, give illustrations of typical results obtained from tlie measurement and tabulation of the eggs. An examination of the graphs shows that, in the collection of undoubtedly mature fish from Warrendale, the eggs were fairly uniform in size, ranging from about 2.5 to 6 mm. in diameter. The ()l)vious graduation in size of the q^^^ in the different age-groups is probal)ly significant of racial differences, but a discussion of this point cannot he given in this paper. In the case of the fisli taken by troll in the ocean the fre(piency-distribution based on egg sizes sliovvs a distinct grouping around several modes which are usually quite well separated. Three modes are especially distinct and, in the case of the collections for which age determinations were also made, and wliich have, therefore, been separated into the component age-groups (.Monterey, 1919, and Columl)ia River, May, 1919) it is apparent tliat the group characterized l).^■ the largest eggs (above 2 mm. in diameter) is composed chiefly of 18 CALIFORNIA FISH AND GAME. li.sh in tlu'ir tliird, i'ourth and fifth years, whose scales show the oeeau type of nucleus, and of fish in their fourth and fifth years whose scales show the stream type of nucleus. [The nuclear growth here referred to is that located close to the center of the scales and represents the portion of the scales formed during the first year. The "stream" type indicates that the fish remained in the stream during the entire first year of its life. The "ocean" type of nuclei indicate that the fish have migrated seaward sometime during the first year, usually early.] The group representing the next smaller size of eggs (1.25 to 1.5 mm.) in diameter is characterized especially by fish in their third year with either ocean or stream nuclei, while the group representing the smallest eggs (.6 to .8 mm.) is characterized chiefly by fish in their second 3'ear with ocean nuclei. The size of the eggs in the group having the largest eggs corresponds, in each instance, with the size of eggs in the AYarren- dale collection and are, therefore, without doubt fish which would have matured during the year in which they were taken. It is apparent, then, that in general the group characterized by tlie largest eggs is composed of fish one year older than those composing the group with eggs of the next smaller size, and that these in turn are one year older than those composing the group with the smallest eggs. These difPerenees in the size of the eggs are not dependent on cor- responding differences in the size of the fish. There is, indeed, a distinct correlation between the size of the fish and the size of the eggs, but, as will be shown in the more detailed report, this correlation is liy no means ample and is unquestionably modified b}" the approach of juaturity. Of particular interest and significance is the presence of two groups of individuals within the same age-group which may be definitely separated on the basis of egg sizes. This is shown with unusual clear- ness in the third j'ear fish with ocean nuclei taken at IMontorey in liHS. The group with eggs greater than 2 mm. would undoubtedly have spawned during the fall of the same year in which they were taken, while the fish composing the other group would not have spawned for at least one more year. These facts which have been so briefly and incom- pletely discussed seem to fully justify the conclusion that the size of the eggs is a fair-ly reliable index of the relative degree of maturity of Chinook salmon. AVithout attempting to discuss further the method used for deter- mining I'elative maturity, a tabular summary will be given of the results obtained by the study of the ten collections which have formed the basis for this report. It is hoped that further study will increase the accurac}^ of the results, and it seems probable that some of the percentages given in the table may be somewhat modified by additional investigations. It is believed, however, that the results as given here are fairly reliable. In preparing the table care has been taken to include doubtful cases always with the more mature of the two groups to which they might be assigned. This has been done in order not to exaggerate the degree of immaturitv exhibited by any of the various collections. CALIFORNIA FISH AND GAME. 19 TABLE I.

From the data contained in these tables the following generalizations may be made: 1. The fish taken in the ocean off the mouth of the Columbia River contain, in the spring and early summer, approximately 70 per cent of individuals which will not become sexually mature for one or two years. 2. By the middle of August this condition has changed so that nearly 90 per cent are fish which will soon enter the river for the purpose of spawning. The rate at which this change takes place and the time at which it occurs have not yet been determined, but will be taken up in the later report. 3. A comparatively small percentage of the fish found ju.st within the mouth of the Columbia River are immature. It should be mentioned in this connection that it is only occasionally when unusual tidal condi- tions obtain that any immature fish are taken inside the mouth of the stream. 4. The fish taken by troll in Monterey Bay in June contain a considerable proportion of immature individuals. The data obtained in 1918 are most reliable, and indicate that only about 40 per cent of the fish taken would have spawned during the same year. The data for 1915 indicates that 75 per cent were mature, but selection may well have taken place in making this collection which, as noted above, consists of egg samples only. 5. The fish taken near Drake's Bay and Fprt Bragg in July and August, 1918, contain approximately 30 per cent of immature fish. It is of interest to note that this is an approach to the conditions found off the mouth of the Columbia River in August and suggests that the composition of all the schools found near the coast changes materially during the summer season. GEAR USED FOR SALMON TROLLING IN CALIFORNIA IN 1920. I'.V W. I-. SCOFIELD. Object. Tliese notes, by no means complete, are intended to be a rough record of the type of gear used in open sea salmon trolling in California at present (1920) as a partial supplement to the system of triplicate receipts for statistics of catch recently installed by the Fish and Game Commission. The fact that gear and methods have changed decidedly in the past few years and no doubt wdll continue to change makes this summary necessary. The notes deal chiefly with gear used. Such subjects as history of trolling, points at which trolling is practiced and its extent, location for trolling in a given local area, prospecting for schools, and deep vs. shallow fishing, although most important, are omitted or merely touched upon here. Variation in Methods. There is considerable variation in methods and equipment, with great divergence of opinion on most of the subjects taken up in these notes. While the industry Avas new this was an advantage, as established custom did not limit experimenting, CALIFORNIA FISH AND GAME. 23 but tlie results of the experimenting were not kept in definite form to be used, each fisherman satisfying only his own opinion without giving others the benefit. As a result there has been much duplication and improvement has been slower than need be. As fishing practice is now more established future improvements will resnlt from more accurate experimenting with definitely recorded results. Location for Trolling. Most of the fishermen move from one region to another following the salmon runs. The Monterey season opens first (January or February) and the local Monterey fleet is doubled or trebled by boats that go do-\vn from northern points, chiefly from San Francisco. Toward the end of the Monterey season (June) these boats begin leaving for San Francisco. They either fish for a time out of San Francisco or Point Reyes or go on up the coast to Bodega Bay, Fort Bragg and Shelter Cove. About August they begin returning to San Francisco. This year several boats, after completing the season at Shelter Cove, went farther north, some bound for Astoria. In a given region the greatest and most difficult single factor in success is picking the good place to troll. Some 'days the big catches are made near shore in shallow water. At other times the trolling is best far out in deep water. In Monterey a quite generally believed theory is> that schools come up from the south, enter the bay to feed for a few days and then leave. Other fishermen cite cases where the schools come from the north. Some fishermen prospect far 'out in order to locate entering schools. Cases are known where such a school has been fished day after day on its way to Monterey and while in the bay. Other schools have been followed far up the coast. In the choice of location most fishermen merely follow some "hunch" and go it blind, keeping an eye on the other boats till they see someone landing fish and then go to that locality. When a large school is biting the whole fleet is often bunched in a small area. A plan often followed at Fort Bragg is to start trolling near shore with a shallow set and work farther out, gradually increasing the depth of line while prospecting for a school. Undoubtedly the successful fishermen have gathered a great amount of knowledge from experience but these "trade secrets" are not discussed freely. A knowledge of the habits of sardines, anchovies and squid is undoubtedly a help to some fisher- men. Little is known of the efl^ects of local currents carrying food and the conseciuent behavior of salmon. Deep vs. Shallow Fishing. The most successful fishermen experiment at different depths and prospect to locate schools. It is a common saying that small Chinooks are caught more often in shallow water near shore. Silver salmon are said to be caught near the surface. There are, however, many exceptions. Some days when the fish are feeding actively the large Chinooks are caught near the surface. A common method of prospecting is to set one line with two to five fathoms of main line out (above leads) and the other line set with 10 to 20 fathoms out. Good catches are made at a great variety of depths on different days and practically nothing is definitely known of the reasons. Whether or not different schools feed differently is not known. Whether or not the weather affects the depth is not known, but some fishermen work on the theory that deep fishing is best on a clear bright day and that the set should be shallow for 24 CALTFORNIA FISH AND GAME. cloudy dark days. Tliis suggests the possibility of plankton sinking to greater depths on clear days, small fish following the plankton and salmon following the small fish. Practically nothing is known of the eft'eet on salmon of different water temperatures. Color of the water is believed by fishermen to be important. Clear water is believed to be poor for salmon fishing and at such times deep fishing is said to be more successful than shallow. Dark, murky or even reddish water is thought to be best for salmon catches and can be fished nearer the surface. The "red water" of deep color sometimes seen along shore is not good for trolling. Boats. The type of boat most used is a clipper bow boat of wide fiare forward and a pointed compromise stern. Often there is a small cockpit near the tiller and a high narrow house open at the back that is little more than a wind and spray screen when standing at the wheel near the engine. As the change from sail to power fishing has been recent there are a number of converted sailboats in use, especially the small Mediterranean type of boat that formerly used a latine sail. ' There are also a number of converted pleasure boats of a great variety of types. The pointed stern is usually favored rather than a rounding fautail stern because with the narrow stern it is easier to haul a fish up alongside on either side while still operating the tiller. Tlie first troll boats were square sterns. Then tlie rounding or fantails were found to be better suited to landing the fish as there were no corners for the line to catch on and the stern is low in the water. The low stem was not so good when the boats began going out farther in rough water. Now that two-line fishing is almost universal the bluntl}^ pointed compromise stern is used most. As fish are becoming less plentiful the tendency has been to use increasingly larger boats capable of going farther out with comfort. The clipper bow type ranges in size from 20 to 40 feet over all with 30 feet as about the average size. The few 40 foot boats usually fish four poles. The older boats have only a small hatch forward to allow a man to crawl below deck. A recent tendency toward comfort has been to raise the forward deck to allow more room below and a number of boats now have a low house extending forward with portlioles to admit light and aii". This could be more general since the forward deck is not used except for stowing the anchor and chain. Nearly all boats carry but one fisherman. The larger boats fishing four lines sometimes carry two men, one handling the starboard lines and the other the port, but frequently one man operates the boat and handles four lines. The catch of a large boat is usually not equal to the catches of two smaller two-line boats, so experienced fishermen prefer to fish alone and not divide profits. INlany of the one-man boats are decked over the stern and this is much more dangerous for the fisherman than having a small cockpit. The gunwale is only three or four inches high, the deck is wet, the boat rolls in a rough sea and while landing a fish the fisherman often has to keep one leg on the tiller so that his chances of going overboard seem fairly good, and once overboard with the engine running and his rubber boots too heavy for swimming, his only chance is to be picked up by some other boat. CALIFORNIA FISH AND GAME. 25 Engines. Boat engines are of one and two cylinders, the majority being one-cylinder. The two-cylinder engines are nearly all 12 horse- power. The one-cylinder engines develop 6 or 8 horsepower capable of giving a boat speed of about seven miles per hour. The Hicks engine is the most popular engine for trolling boats, but there are many Standard engines in use. In all there are about 20 different makes used, including the Ford automobile engine. Eastern engines built for pleasure boats are also used, such as the Buffalo and Scrips. Most of the boats under 30 feet long have a one-cylinder and boats over 30 feet have a two-cylinder engine. Sjjeed of Boats. Wlien trolling the engine is choked down till the boat travels at from 2 to 4 miles per hour, 2^ to 3 miles is usually preferred. The speed is greater when fishing near the surface. The deeper the lines the slower the boat is run. This is partially based on the theory that the fish on the surface are more active in taking bait or spoon and that fish deeper are more easily tempted by an object moving more slowly. A greater influence in slowing down for deep fishing is the fact that the line may be given a deeper set with the addition of but few extra weights. The slower the speed the deeper the set for a given amount of leads and hauling in a deep set, heavily weighted line on a rapidly moving boat with the resulting water drag on the line is back breaking work, so that the theory of deep fish being more sluggish fits in nicely. The speed is greater when fishing spoons rather than bait is used. Most spoons do not have the proper motion (spinning or side to side weaving) when the boat is run as slowly as is customary in bait fishing. Poles. Poles are made from yoimg peeled saplings, seasoned and trimmed down, usually of pine, eucalyptus or Douglas fir. Many bamboo poles are used, a single large pole or three small diameter poles lashed together. Often a short section of bamboo is lashed to the pole near the tip as a reinforcement at the point where a break is most apt to occur. For small boats a general rule is to have the length of pole equal to the length of the boat as this is believed to give better balance. Boats using four poles have two short poles forward and two very long poles aft. Twenty-five feet is about the average length of pole. Placing of Poles. Since there are many different styles of boats used there is great variation in the arrangement and position of the poles on the boat, each fisherman following his own ideas to best fit the deck plan of his boat. In some cases the poles are far forward, in most cases amidships and in some cases far aft. When the boat is small and of narrow beam the poles are usually crossed so that the base of the starboard pole rests in the scuppers of the port gunwale. This arrangement does not require a mast. In large boats the poles are used with a short mast, the base of the pole fitting into a socket or bolted at the foot of the mast. Since the distance from the mast foot to the gunwale is short, the pole when under strain has a great leverage. The strain is relieved by guy lines run from the bows. When very long poles are used even on larger boats they are some- times crossed thus giving a longer pole base support within the boat. Pole Supports. In all cases the pole has a vertical support on the gunwale to give the tip the necessary elevation. These supports may be simply two boards nailed together like a letter X, or a single board 26 CALIFORNIA FISH AND GAME. with a U notch ent in tlie upper end to receive the pole. Some have a notcli cut to curve aft so that the pole jams in and is held down tight when the boat rolls violently. Other supports are made by bend- ing the end of an iron rod into a U-shaped receiver for the pole. Stoiring Poles. When not trolling the poles are seldom left spread because of the danger of being broken. In some cases they are laid on deck along tlie gunwales, sometimes lashed to the top of the house with their bases in the bows, often drawn up vertically beside the short mast, fitting in notches at the mast liead. Sometimes the pole base is hinged so that the poles may be lowered aft against the top of the house. In a few cases the mast is set on a hinged base so that mast and poles may be low^ered at night or to pass under a bridge. Pole Line. In trolling the main line is not attached to the pole directly. There is a short large-sized line or "pole line" with one end tied to the pole tip and the other end provided Avith a snap hook which is snapped into the main line at any desired point. The upper portion of the main line then hangs loose from the snap to the stern of the boat and provides a very convenient method of pulling in the line, since the pole line and snap are from 15 to 25 feet out from the stern while trolling. Fig. 13. Diagram showing gear arrangement on a salmon boat. The pole line is a few feet longer than the pole so that it may be unsnapped from the main line and snapped into a cord loop on the gunwale near the stern when the main line is being hauled or when the poles are stowed against the mast. This arrangement easily allows the main line to be fished at any desired depth. The snap may be used in the loop of any lead or in loops tied in the main line two and one- half or five fathoms apart. The main line loop is made by doubling back the line and tying a simple hard knot leaving two or three inches free to form the small loop, just enough to receive the snap conveniently. CALIFORNIA FISH AND GAME. 27 Plan of Rig. Although there is great variation in details of the arrangement of weights and line the "taper line" is almost univer- sally used. The taper line is heavy (large) at the top, tapering in size toward the bottom. The size of the leads also tapers off, with the lightest at tlie bottom. The object of the tapering size of line is largely to avoid loss of the whole line when the lower hooks catch on rocks. Arangemen^ of Taper Line^^ /Mainline M6econcll.ead "/Od Crhraada) 7/h. Lead ^Bef^eeZ"''<>r><./,.^^ - Fig. 16. Diagram showing metliod of attacl^ment of leader to line. The usual method of attaching the leader is to tie a "running knot" in the main line which leaves the line straight as if threaded through three or four wraps of itself. The name "running knot" refers to the fact that the line runs straight through but the knot itself is perfectly solid. The line is then threaded through one ring of a swivel and anotlier running knot tied at from two to four inches from the first. The leader is then tied into the other ring of the swivel with a bowline. The swivel protects the main line from being twisted by the leader and the distance between knots allows some play for the leader Avithout crawling up or slipping down. The Avire ring of the swivel is apt to wear on the lower knot and to avoid this a short wire section is some- times inserted in the main line. This wire is about two inches long, threads through a swivel ring and looped at each end with the ends wrappcul into a .shoulder to keep the swivel. The main line is tied with a bowline into each loop of this wire section. By this arrangement the swivel plays on wire but the strain of the whole line now falls on the loop of the bowline bearing on the wire loop and this is apt to cut under a heav.y strain. Bait vs. Spoons. There is the greatest divergence of opinion among iishermen on the relative merits of spoon and bait. One fisherman will remain in because no fresh bait is available, another will use nothing but spoons, another insists on having both, Avhile most fisher- men change from one to the othei' at different times in the season. At Fort Bragg, for instance, there is a general belief that the spoons are more successful during the early part of the season and that bait is better for the latter part of the season. The majority of fishermen CALIFORNIA FISH AND GAME. 33 prefer fresh bait, but when it is difficult to get or expensive, they use spoons. At Monterey most of the Japanese prefer spoons through- out the season and most of the white fishermen prefer bait at all times even when it has to be purchased at from 15 cents to $2 a bucketful. A few half-hearted experiments have been tried by using one line baited and the other rigged with spoons, but such trials have been brief and the findings merely personal opinion rather than actual figures of the catch. A fresh sardine about seven inches long is almost universally pre- ferred as bait. Squid tear off the hook. Anchovies are too small. Salted and formalin-preserved sardines are occasionally used but without much success, generally attributed to the loss of the bright shining appearance of the fresh fish. Spoons. A variety of spoons are used, no one being a universal favorite. A number of fishermen prefer the hook attached solidly to the spoon (as in the Dubrow) because they believe that the salmon is more apt to be hooked, claiming that the swinging hook is apt to be brushed aside. Some fishermen prefer the Wilson spoon with a free swinging hook that is attached about one-third of the way up the spoon, because thej^ believe this arrangement is more apt to hook the fish. However, most makes of spoons have the hook swinging from the lower end of the spoon, as in the McMahon, Diamond and Kewell- Stewart. 0 ^ rri^DC A^AKh K-. HONf MADE SPOON. A.L. InllLSON. No.eB. DIAMOND /Vo. e. Fig. 17. Various types of salmon spoons. 34 CALIFORNIA FISH AND GAME. Tlie chief consideration in any spoon is its shape to govern its motion in the water. Although the spoons are of polished silver plating or brass to attract salmon by their shining, it is their action in the water resembling a swimming sardine that is most important. Some spoons are designed to spin in the water with a wriggling motion. Most spoons zigzag Avhile constantly tipping from side to side so that the broad shining surface is displayed as often as possible. The Dubrow spoon for instance is curved to give a zigzag motion when trolled slowly and the tails are curved propeller fashion to spin the spoon when moving more rapidly. The McMahon spoon was the most popular at Fort Bragg during the 1920 season. This spoon tips rapidly from side to side when trolled and follows a fairly straight course. This tipping is continued even when the speed is greatly slowed down and the Mc^rahcn's popularity is largely due to the fact that it can be trolled slower than most other spoons. The Stewart and Wilson spoons tip less from side to side but follow a more zigzag course. Fishermen w-ho have used Dubrow, "Wilson, Stewart and McMahon spoons almost equally throughout a season claim to have had equal success with all four spoons but favor the Mc^Iahon because it is successful at a slower speed. There are quite a few home-made spoons in use, the spoon being cut from a sheet of plated brass. A successful home-made spoon is made on the Dubrow plan by riveting in a No. 11 or No. 12 long- shanked eye hook. Home-made spoons of the Kewell-Stewart type are most frequently used and are more easily made than the other types. The Wilson type is also seen frequently and is comparatively easy to make.

The size of the spoon does not vary greatly, No. 6 and No. 7 being the favorites. MeMahon No. 7 is used most although some No. 6 are used. The No. 6 Dubrow is used more than the No. 7. In Kewell- Stewart spoons No. 7 is used most. In Diamond spoons, No. 6 is preferred. Bait Hooks. When fresh bait is used (sardines almost universally) the hook is passed twice through the head (through the eyes) of the sardine so that a couple of firm hitches are made on the head by the line. The sardine is then bent to one side at about the same curve as that of the hook and the hook passed through the body longitudinally, in at the mouth and the curve of the hook out at the anal opening leaving the shank of the hook inside the body. Because of this pre- ferred method of attaching the bait a long shanked hook with a knob head is used. The knob, much like the head of a finishing nail, is the diameter of the shank and is formed by the shank diameter being reduced just below the knob. Many of the hooks are made in Norway, especially the Kirby hooks, which have a slant to one side in addition to the curve so that the point sets at an angle to the shank. Most fishermen prefer a straight hook without the side slant and the Kirby hooks are often straightened in a vise before using. In all hooks the point is considered to bend in too sharply toward the shank and most fishermen bend the points outward a little before using. When using a short- shanked hook the bait is more apt to be swallowed by the salmon and the hook is then difficult to extract and the leader is more apt to be cut on the teeth of the fish. A hook wnth a large diam- eter at the curve is pre- ferred because it is less apt to tear out of the salmon's mouth. The sizes used range from No. 9 (small) to No. 13 (large), sizes 11, 12, and 13 being used mo.st. There is a quite general belief among fishermen that the first of the season runs small fish and the end of the season large fish. Some fishermen therefore use No. 11 sized hooks at the first of the sea- son and No. 13 toward the end of the season. No. 12 is the most popular size for bait hooks. Hooh and Spoon Leaders. A No. 33 cotton leader attached to the hook knob would be too large for convenient threading through the bait. For this reason a short hook-leader is used, a line of Irish linen Fig. 19. Kirby hook No. 12. Natural size. 36 CALIFORNIA FISH AND GAME. being preferred as it is small, light, pliable, and strong. The most popular make is the Cuttyliimk, a three-strand linen bass line. The sizes used range from 24 to 60 but the sizes 27 and 42 are used most although all sizes between are occasionally used. For hook-leaders a No. 6 or No. 7 Irish flax salmon thread doul)led is sometimes used. Other fishermen use No. 7 airplane thread doubled and twisted. Such thread is attached to the hook by taking a piece four or five feet long, making a double half or clove hitch over the hook knob in the center of the thread and twisting the ends. The length of the hook leader varies from one and one-half to three feet, two or two and one-half being preferred by most fishermen. A swivel is used between the hook-leader and main cotton leader, using a bowline at each end of the swivel. Some fishermen think that the loop of the bowline over the Cuttyhunk leader cuts in and weakens the leader, so they double back the end and tie a plain hard knot in the doubled Cuttyhunk. This may be attached to the swivel end by inserting the loop through the swivel eye and threading the hook and leader through the free end of the loop, making a reef hitch. This hitch also has the advantage that the hook and its leader may be removed by unthreading without untying any knots. This same hitch is frequently used at the lower end of the main leader where it attaches to the swivel, especially when a wire spoon leader is used. The main leader is less apt to cut on the swdvel eye but the chief advantage is that the swivel, wire leader and spoon may be easily removed without untying any knots. When spoons are used a Cuttyhunk spoon leader is sometimes used but a short wire leader is usually preferred because the linen thread is apt to be cut on the fishes' teeth, and especially when a shark is hooked or is attacking the hooked salmon. For this purpose a two or three foot brass or plated brass wire is generally used, belt lacing wire being the favorite as it is pliable and very strong, but it can be broken if the fish in thrashing about gets a kinlc in the wire. To avoid this some fishermen use piano ware since it is exceedingly strong and so stiff that it is not kinked and broken, but its stiffness makes it much more inconvenient to handle, especially in removing spoons. In order to overcome this inconvenience some fishermen use some form of home- made stiff wire snap or fastener to free the spoon. This snap is sometimes inserted just below the swivel so that the wire leader is removed with the spoon, or just above the swivel of the spoon so that the wire leader remains attached to the main cotton leader. Some such scheme for easily removing the spoons is a great convenience because the wet spoons soon tarnish when left exposed to the air. To prevent tarnishing the spoons should be removed at the end of the day's fishing and placed in a bucket of salt w^ater or wet sand. The swivels used are of two types. INTost spoons sold in the stores have the closed or barrel type attached but the wire knobs inside the barrel may wear dowm and break. The open type of swivel is preferred because the Avire knobs can be seen through the openings and the sAnvel exchanged for a new one Avhen wearing occurs. Markers. In prospecting for a school a boat may be trolling for some time with no sign of fish and then suddenly have two or three strikes at once on each line. By the time the fisherman hauls in and resets each line considerable time has elapsed and the boat has covered CALIFORNIA FISH AND GAME. 37 quite a distance. It is then difficult to circle back and pick up the spot where the strikes occurred. Some fishermen carry a marker that may be heaved overboard at the point where the strikes occur so that the place can be picked up again without trouble. The marker is a small float that supports a light flagged pole 6 to 10 feet long. The lightest marker is a cork float about 18 inches square and 4 inches thick, supporting a bamboo pole. The float is often of wood. The flagpole is passed through the float and weighted on the bottom end to insure floating upright. Detecting a Strike. The drag of the line bends the pole tip back- ward. The rolling of the boat causes a motion of the pole tip due to lessening and increasing strain, but this slow movement with the boat roll is easily recognized and not confused with the more rapid jerking of the pole tip when a salmon is hooked. Stiff poles are more apt to break wath the sudden extra strain of a boat 'roll. In some cases this is obviated by using a coiled wire spring at the pole tip, but springs have not met with general favor. Landing Fish. Hauling in the line takes some time and the hooked salmon has time to wear himself out fighting against the drag of the leads so that pulling him alongside is usually a hard dead pull without excitement. In shallow short-line fishing the salmon is more quickly pulled in and often puts up a hard fight, charging back and forth, even jumping elear of the water, tangling the gear generally and sometimes wrecking it. Silver salmon are credited with fighting much harder than Chinooks. Small Chinooks are said to fight harder than large fish, but this is probably due to the fact that small fish are more frequently hooked near the surface and on the shorter lines. Some fishermen use a large landing net to bring the fish on deck, but a gaff hook is more commonly used. Sometimes the fish is so exhausted that he may be landed by a hand inserted in his gills. To prevent the fish flopping on deck he is killed by clubbing over the head with the gaff hook or a special club carried for the purpose. Hauling in Lines. Practically all hauling in is done by hand. A few fishermen have small drums operated by the engine with rod and gearing, but this power hauling saves only the first (and hardest) pull to the first leader as weights and leaders can not be wound on the drum. To prevent the line cutting the hands most men wear over the fingers a three or four inch section of automobile rubber inner tubing. The stores sell rubber "clinchers," which are a circular band of thick rubber with a sunken grove for the line and intended to be worn over the hand as is the auto tubing. The clinchers seem to serve better when cut in two and a cord used over the back of the hand instead of the complete rubber ring. The line is coiled on the deck or in a small cracker box with the hooks inserted in notches in their proper order. The leaders are coiled separately from the main line in a smaller coil near the hook so that the bait or spoon can be thrown far out and tangling avoided. Lost Fish. An attempt was made to learn the percentage of strikes that are lost but no records are kept and the opinions of fishermen are at such variance that nothing of value was learned. The percentage of lost fish evidently varies from time to time, possibly with the degree of hunger of the fish. Fishermen claim that on some days one-third of the strikes are lost, but on other days practically every fish is landed. 38 CALIFORNIA FISH AND GAME, Whether or not small Chinooks are lost more than the large was not determined. The majority of fishermen think that many more small fish are lost than large, but they cannot be sure but that the small fish were silver salmon in most eases. Opinion is agreed that silver salmon are lost more than Chinooks and two reasons are given. Silvers are said to fight harder and their mouths are more tender. It is noticeable in looking over a mixed catch of the two species that many of the silver salmon have the lower jaw torn apart. Salmon after being securely hooked are of ten ' attacked by enemies that are following the school. This is apparently more common in the northern waters, but is not uncommon at Monterey. Sea lions and seals are said to play a part, but sharks are the chief offenders. Sharks are often seen following a hooked salmon while the lines are being hauled in, even coming alongside, pursuing the salmon till he is hauled out on deck. It is no uncommon thing to see a 15-pound salmon delivered that has been bitten in two, leaving only the head and a little of the body on the hook. Spoons, leaders and leads are often lost from sharks biting off the lines and trolling is seriously interfered with, particularly along the northern coast and especially at Nogo and Shelter Cove. THE FUTURE OF THE SARDINE.* By Will F. Thompson. Our greatest fishery is that for the sardine ; indeed, it is overwhelming in importance, constituting during January, February and March of 1920 about 85 per cent of the total fish of all kinds taken. Will the sardine remain, or will it vanish at times as does its cousin the herring of the North Atlantic, and as the sardine itself probably does in British Columbia and Alaska? Upon the answer to that question depend millions of dollars and the welfare of a great industry. What are we doing to answer it? We have not known thus far whether or not our sardine fishery is subject to great fluctuations — its history is so brief, having begun in 1914. It is possible to surmise that it is, because in the North Pacific this same species of sardine was practically unknown until two years ago — indeed the occasional specimen that was taken with the herrings was hailed as a curious stranger. Then they came in a great flood, cluttering the traps and the nets, and a canning industry of importance sprang into being. And if they were lacking once they may well be lacking again, not only in British Columbia but in California. So the most ordinary business sense dictates an energetic inquiry into the probability that such great changes will occur in California, and into the chance of foreseeing them. This is, you will note, entirely aside from the chance of overfishing. And we do not know enough about our Pacific fisheries to know whether they can stand anything approaching the strain that the Atlantic herring and sardine have stood. Perhaps even in the Atlantic it is possible that the herring or sardine will one day suffer from man's * California State Fisheries Laboratory, Contribution No. 22. CALIFORNIA FISH AND GAME. 39 operations as have other species. Our experiences on this coast have not been reassuring — that is certain — as witness the disastrous story of the halibut and salmon, for which our only great fisheries existed before the sardine and albacore became of importance. But before we can discuss overfishing, before we can tell whether it is happening, we must know something about those great fluctuations mentioned above, which may be confused with it. Indeed, in the sardine fishery the great natural changes in abundance may be so overwhelming as to completely overshadow depletion. To the study of these changes in abundance we have therefore addressed ourselves earnestly, along lines suggested by a scrutiny of the phenomena in the herring and other fisheries. It has been shown that the relative success of the spawning seasons is of predominant import- ance in explaining these changes. It has been found in the herring fishery that in some given year the spawning was very successful, and that the result was a vast number of herrings of a single age, and as year after year this great age-group became older it made the fishery very successful for that particular size to which it had attained. To make this point clear a diagram is attached which, while it does not represent the actual condition in any particular fishery, may for our purposes be thought of as applying to that for the sardine. The successive years are shown at the various levels, and the ages are shown in succession from left to right. With each passing year the groups fall each into the next higher age class, and thus the predomi- nating group passes successively through the ages from the third to the eighth. The oblique line traces its eourse. The height of the blocks represents the relative importance of the particular age considered in the catch. It will be noticed that each age-group becomes smaller as the years go on, because of the annual natural death of a certain proportion, in this case assumed to be a fourth. In the case of the herring a successful period of fishing was ushered in by the incoming of just such a highly successful age group as is first shown in the third year old class on the diagram, and a poor period was characterized by its lack. Such a phenomenon may be happening in our sardine fishery; and we are analyzing the catch to see whether it is or not. For instance, during last season, the first we investigated, the group we may regard as being in their fourth year predominated and made, at Monterey, a good pack for "half-pound oval" cans, much as the dominating class in our diagram was in 1904. Will this year's catch be of fish one year older, hence less choice, and will the next be of fish two years older? Or will the catch continue to be of the same size and equally good for packing such cans 1 In other words, do the age- groups of fish vary widely in their abundance, as we have represented in the diagram, and will the fishery vary between success or failure with their growth in size, and with the presence or absence of a success- ful year? The packer, wondering whether the fishery is to remain good, and whether he will be able to pack "quarter oil" sizes, or obtain good "half-pound oval" sizes, naturally wishes to know the answer. We already have the catch of last year analyzed. What will our analysis this year show ? It should, if we obtain our material and know from it 40 CALIFORNIA FISH AND GAME. ..... 1 _pg ■ 1 ^1^^ \ i \ M 1 \ b \ 1 ^ H «E Fig. 20.

Per- haps, when we know the exact rate of growth, we may be able to prophesy very exactly the character of the catch. Who knows, indeed ? But note the proviso, if tve knoiv the rate of groivth. That indicates the importance of the fact upon which it is necessary to lavish much care and thought. It is a cornerstone for our edifice. So we are concentrating upon age and rate of growth. Yet this knowledge of age is not sufficient unto itself. We must know whether our analysis of the catch really shows which age predomi- nates. And there is only one way to do that, namely to take extensive series of samples for observation and comparison throughout the year. So there are two men stationed, one at JMonterey and one at San Pedro, who are doing nothing else. Last year we obtained a great series of samples and are subjecting it to the closest analysis to see whether the age that predominates does so because of its actual abundance or because of some influencing factor. And so, also, the same is being done this year for comparison, to see whether the dominating class does become a year older. So far as we know, no fisheries investigation has been based as thoroughly and as carefully as will be that of the sardine. And so we are confident that we will be able to answer the queries of the packer and the fishermen. We will be able to determine whether or not the fishery is to be one that varies gi'eatly from success to failure through periods of years. We will be able to prophesy, if it is possible, as to the character of the coming catch. But our objects are also to meet many other queries of the dealer, the packer, the fisherman, the legislator and the public, and what we have said in this article covers but one phase of our investigations ; there are others as important. And we hope ultimately to be able to meet competently and scientifically that grave question which always awaits us in all discussions of the fisheries, that of the presence, the absence or the probability of overfishing, and its remedies. 42 CALIFORNIA FISH AND GAME, CALIFORNIA FISH AND GAME A publication devoted to the conserva- tion of wild life and published quarterly by the California State Fish and Game Commission.

Certain details of the life history of the Chinook salmon, one of California's finest food fishes, have long been a mystery. Does a salmon always return to the stream where it was born? Why do salmon refuse food when in fresh water? Where do the two- and three-year-old salmon feed when in the ocean? Answers to these questions are being sought by scientists to complete our knowledge of the life and habits of this notable fish. In this January issue of California Fish and Game we present a "Salmon number" containing sieveral contributions bearing on the above points which merit thorough perusal by all our readers. Not only are these papers of more than ordi- nary interest so far as subject matter is concerned, but those by Dr. J. O. Snyder and W. L. Scofield are published results of the marking experiments and other investigations on salmon undertaken by the California Fish and Game Com- mission. KLAMATH RIVER SALMON THREAT- ENED WITH EXTERMINATION. The Electro-Metals Company of San Francisco and Mr. A. P. Seybold ot San Francisco, have each applied to the Federal Power Commission for prelimi- nary permits to build dams on the Klamath River to divert water for power projects. One of these projects is located above the town of Orleans and the other a few miles below this place. Nothing in recent years has so threat- ened the salmon fishery as these pro- posals. The Klamath River still has a good run of salmon. A large cannery is located at the mouth of the river and large numbers of fish are used for food by people living along the stream. A large take of salmon eggs for the use of the hatchery is also secured on the Klamath River near Hornbrook. If the Federal Power Commission permits the building of these dams, 90 per cent of the spawning ground of the salmon in this river will be destroyed and ultimately the whole salmon run. The power companies will argue that fish ladders can be built over the dams. Ladders, of course, could be built, but there is little chance that they would be successful on dams 100 feet high, or over. Furthermore, such fishways would be an impediment to the young salmon attempting to reach the ocean from the spawning grounds. Nor could a success- ful hatchery be maintained below these dams, for the salmon reaching such a station would not be mature and it would be impossible to hold them until ready for spawning. The catch in the Sacramento River and other rivers in Alaska has fallen off during the past few years, and unless some of the better streams are protected as spawning grounds for these fish, the salmon will soon be a thing of the past. There is no opposition to power projects in general, but there is opposition to pro- jects which destroy spawning grounds of salmon and other food fishes. Other streams where there is a poor salmon run, as' for instance the Trinity River, should be utilized rather than the best of our salmon streams. It is to be hoped that the above appli- cants will be denied permits and that the Klamath River and its tributaries will be permanently maintained as spawning grounds for salmon and steelhead, and thus continue to be a source of supply for the fishing industry and a resort for the angler. CALIFORNIA FISH AND GAME. 43 IN MEMORIAM. RALPH W. REQUA. Ralph W, Requa, a former trusted employee of the Fish and Game Commis- sion, departed this life July 7, 1920. Ht was born at Xenia, Kansas, November 26, 1874, being the son of George W. Requa, one of the pioneers of Kansas and a prominent citizen and politician. Ralph Requa graduated from the schools of his native state and at the age of eighteen entered the United States Postal Service as a delivery mail clerk, 1'his work was not to his liking, as he was interested in the conservation of fishes, so he soon entered the employ of the United States Bureau of Fisheries. For several years he was employed as a messenger in the distribution of fish by the Federal Bureau of Fish- eries, and the knowledge he obtained iu traveling over the different sec- tions of the United States in this work, was of great value to him later. Mr. Requa resigned from the Bu- reau of Fisheries iu June, ISDj, to accept a position with the California Fish and Game Commission. He was placed in charge of the distri- bution work at Sisson Hatchery and subsequently became foreman and assistant superintendent, greatly as- sisting in the building up of this hatchery, as his practical knowledge was of great value in all lines of fish- cultural work. Considerable of his energies were devoted to the improve- ment of automatic screens for the saving of fish from destruction in ditches and canals, and he patented several de- vices for this purpose. Many of the best screens in the state have been installed under his direction. His arduous duties as superintendent of one of the first distribution cars under- mined his health and for the last six years he was employed only periodically by the Commission on screens and aquarium exhibitions, although in charge of the salmon experimental work at the experimental station in Bidwell Park near Chico. An expert on the arranging and placing of fish in acquariums, his work at the different county and state fairs attracted wide attention. He was married to Florence Getchell in 1001. Her death in November, 1918, hastened his end. He left two children, Francis and George Requa. Untiring in his efforts in all lines of fishculture, there was no day too long or task too hard for him if he thought the work depended on his services. He was one of the faithful employees who have made the work of the California Fish and Game Commission one of the most successful of any in this or any other state. Ralph Reqira was a man of the highest integrity, and his associates will ever remejnber him as a kind friend and a loyal champion of those whom he trusted as his friends. No nobler tribute can be paid him than the following extract from Ralph W. Requa. a letter written by a friend and colaborer of his in the work of the Fish and Game Commission : "He went with me into the high mountains and started me right In the fish planting business. I learned him then, the heart of him, as men will do when all alone in the high country. I formed a strong attachment for him and have always held it. He was another example of a faithful employee, martyr to a cause." In the passing of Ralph Requa, the state has lost a good citizen, his children, a kind and loving father, and the Com- mission a dependable and faithful em- ployee.—W. H.

Out- standing features of the past biennium are: Th? successful rc-aring and plant- ing of over 30,01)0,000 trout and over 2lJ,5CO,000 salmon ; the splendid adminis- tration of commercial fisheries and val- uable scientific researcli connected there- with: the establishment of a great chain of game refuges; and a worth wliile edu- cational and ])ubli(it.\' campaign. SPORTSMEN'S AND ANGLERS' ORGANIZATIONS. The sportsmen's and anglers' organiza- tions of California or any state may be considered as wild life ecfucational assets. Through them a greater number of people are made familiar with the fish and game laws ; right sportsmanship is stimulated and the importance of conservation It better appreciated. The Fish and Game Commission stands ready to encourage these clubs in any way possible, for it feels that by cooperating with them both the sportsmen and the Commission will be benefited ; the sportsmen will be more alert to the work of the Commission in its effort to insure the ever increasing numbers of fishermen and hunters with an adequate supply of fish and game, and the Commission by being more in touch with the people, will be better prepared to meet their demands and any lurking spirit of diss'sitisfaction. The Commission feels that it can be of service to these organizations by loaning its splendid wild life films (or stereopti- con slides) and providing a lecturer to explain the pictures, when desired, and acting as a clearing house for dependable information on game resources, fis'h and game conditions and fish and game laws. PROPOSED FEDERAL HUNTING LICENSE.

The congressional ai)i/ro- priation of .i?142.;'in ana i>e number of salmon taken in the ocean must surely lessen the number that enter the river to breed.

SOME CONSIDERATIONS CONCERNING THE SALTING OF FISH. Mr. Donald K. Tressler of the Division of Fishery' Industries, U. S. Bureau of Fisheries, has recently carried on some very interesting experiments on the salt- ing of fisii.* Mr. Tressler's work has to do ehiefiy with the fishes of New England and the Eastern coast, but a study of his work niiglit be of benefit to the packers of the Pacific coast. I*revious to this time very little work had been done on this phase of the fishing industry. It required the stimulus of the enormous demand for food caused by the war to arouse an interest in fish salting and a demand for better methods, 'i'he iHU'iiose of tlifsc ex])eriments was to w(irk out, if iiiissihlr. a method of salting lish applir-aliif in naniiiT cliuiatcs, ?•• degrees Fahrenhrit and abu\e. Tiie standards of quality differ from place to place, some localities demanding a hard, dry, salted fish, while others want a white, colorless fish with a softer meat. Two methods of salting are now in com- mon use on the Eastern coast, the dry or "tight packed" method and the brine or l)ickle method. The former method is almost universally used in the south and the other method in the north. From a study of the procedure followed at the various places on the Atlantic Coast where fish are salted it would seem that there are perhaps three general methods of applying salt to the fish : (1) the fish are immersed in a solution of salt which is kept saturated, or nearly so, by the addition of sail from day to day; (2) the fish are imckcd in wati-r- liglit coiilaiuers with dry s:ilt iiiid are allowed to develop their own pickle; *Sonie considerations concfiiiing the salting of lisli.

This last way is only used in cold weather in an emergency when no containers are at hand. In storing of salt fish, these general methods are in use: (1) brine; (2) dry, with salt; (3) dry, with boraoic acid. In case the first one is used, if the pickle becomes dirty, fresh pickle (salt solution) is added. New brine is always added if the fish are to be stored where it is not cool. If the fish are packed dry they are either sprinkled with dry salt or salt containing four-tenths per cent boracic acid. In all cases the fish must be kept at low temperature if stored for any length of time or they are very likely to "rust." "Ivusting" is due to oxidation of the fish oil. giving the fish a dark-brown color. Packing in brine prevents this to a large extent. Mr. Tressler has fouiid llial llic iiMpiiri- tics in salt exert a great infiuenco on may be kept at a higher temperature than fish salted in brine ; the removal of all blood and viscera, including milt and roe, is absolutely essential for the salting of fish at high temperatures ; and that during warm weather freshness of fish is essen- tial to successful salting. From the results obtain(>d by Mr. Tressler, it seems very probable that fresh fish may be salted in any climate of the United States if the following precautions are taken : 1. All viscera and blood must be removed in cleaning. 2. Large fish must be split. 3. Fish must be salted in reasonably fresh condition. 4. No brine should be added in salting. 5. Salts low in calcium must be used. —A. W. Wki.I„S, Hitrctni of /■'islnri'-'i I'rcscrratioii Lfihuratoru. Fig. 25. Seining- for salincin on the Sacramento Ri\-er near William's I>ar. n-aph by R. B.

The commercial method of catching salmon, by trolling is described in an article by W. L. Scofield in this issue. The catching of salmon by this method has now become an industry of great importance to this state, Oregon, Wa.sh- ington and Alaska. The principal trolling districts in this state are in Monterey 5() CAT.IFORXIA FISH AND CAME. r.ay. n(T 8aii ]''raiuisoo ii(l(ieiiio County. At each of those iilaoos about five huiulrod boats were cniplo.xcil this year. Before sea trolling became iiuiiortaiit in California salmon were nearly all causht by means of nets in tlie rivers which they enter at maturity for tlie purpose of spawning. To show the catch by these two methods we give the following from an article on "Ocean and Stream Salmon Catches," in tVe Octolier issue of this magazine : Total Ycurlii Salmon Catch of the /S7afc in Round Nvmbets. River cauffht 1919 5,987,000 1918 7,173,000 1917 5.493,000 1916 5,342,000 Ocean caught 7,158,000 5,920,000 5,563,000 5,501,000 Season total 13,145,000 13,093,000 11,056,000 10,843,000 The salmon caught in ^lonterey Bay, off San Francisco and in the Sacramento River are generally classed together as a unit under the assumption that they are the product of the Sacramento River. The following table shows the catch by tiolling in those two outside regions con- trasted with the catch by nets in the river : Monterey Bay «"'«;■'« S-J" Francisco Bay 1919 2,816,000 1,443,000 1918 2,893,000 1,929,000 1917 3,880,000 1,280,000 1916 5,231,000 263,000 Troll flsh Sacramento Kiver 1919 4,259,000 4,529,000 1918 4,822,000 5,938,000 1917 5,160,000 3.971,000 1916 5,494,000 3,451,000 It will be S'oen that the Monterey Bay catch has been falling off. Contrasted with this is the catch in the Fort Bragg region which has stoadilv increased due ""♦wywaa- »^ MM r CALIFORNIA FISH AND GAME. 57 to the receut development of the industry at that point. The catch near Fort Bragg was less than half a million pounds in 1917, in 1918 it exceeded' one million pounds, in 1919 it was a little less than three million pounds, and this year the catch exceeded three million pounds. This catching of the salmon in the open sea has added greatly to the diffi- culties of conserving these valuable fish. Our state laws provide for closed seasons on all of our salmon streams during which time salmon may not be caught. These closed seasons were mostly estab- lished before the development of sea trolling and were designed to allow at least one-third of the fish to pass up the rivers to the spawning beds unhindered by nets, under the belief that if this portion of the run, together with the number which escape the nets during the open season, could reach the spawning beds the run would be maintained. If these closed seasons let just enough salmon reach the spawning beds for the perpetuation of the species, then tht additional catching of the fish by trolling in the sea before they enter the rivers will be subjecting them to just that much overfishing, for if one-half of the run, we will say, is caught in the sea before it enters the river, the river closed season, instead of protecting one-third of the run as intended, protects only one-sixth of it. It is our belief that the closed seasons on the Sacramento River were not suffi- cient for the purposes of propagation even before sea trolling came into general practice. The fall season, instead of closing before the latter third of the run has entered the upper bays, does not close until after the last salmon are well up the river and no portion of the run escapes running the gauntlet of nets. This insufficient closed season, coupled with the increase of trolling at Monterey and ofl: San Francisco, has resulted in a decrease in abundance of the Sacramento salmon. This decrease in abundance is shown in the fact that the number of salmon which reach the egg-collecting stations) of the United States Bureau of Fisheries on the upper Sacramento Kiver averages less than one-half that of a few years ago. At the same time, in spite of more energetic fishing, the commercial catch has not increased, even if we con- sider all the salmon caught in Monterey Bay and off San Francisco as Sacramento fish. There is no question but that the Sacramento salmon need decidedly more protection if we are to save these fish from destruction. This need of added l^rotection has been increased by a deci- sion of the Sujierior Court of Contra Costa County which permits fishermen to net salmon on Suisun Bay and the lower Sacramento River during the sum- mer closed season of June and July; and also by irrigation and power dams under consiruction and to be built which Avill shut off important salmon-spawning grounds lying above them. Fishermen who fish with nets on the bays and rivers think that the sea trolling should be stopped or radically restricted, contending that the trollers are destroying the salmon by catching large numbers of immature fish. Salmon trollers, on the other hand, contend that the sea is the proper place to catch them and that after they have entered the river for the pur- pose of spawning they should not be ranght. There is considerable merit to the arguments on both sides of this question. We are convinced that both methods of fishing need to be radically restricted, and that the time is now here when the laws should be made so as to best conserve the salmon and should not be compromised to suit different factions of fishermen on the plea that the state owes them a living. Salmon on the Sac- ramento need far more protection than they are getting under the present law, even if sea trolling is greatly restricted. Netting of salmon should not be per- mitted above the city of Sacramento, the summer closed season of June and July should be restored, and the fall closed season should close two weeks earlier. It is true that a great many of the salmon caught by trolling are immature as is well shown in the paper on the "R-dative Maturity of Salmon Caught by Trolling," in this issue, by Willis Rich. From investigations which have been made" it is not clear that trolling is a more destructive method of fishing than is netting in the river. There are evi- dences which indicate that a salmon fishery may produce more pounds wuthout depleting the supply if the fishing is car- ried on only in the sea. It is our belief. 58 CALIFORNIA FISH AND GAME. however, that until our investigations throw more lijrht on this suhject, closed soason.s sliould he osliihlisliod in tho trdll- inj? districts during those times of tho yoar when the majority of the immature fish are caught. These restrictions should not be so severe as to discourage the develop-- ment of our sea fisheries, for the future expansion of our fisheries must be through sea fishing as our inland fisheries are now being taxed to their utmost capacity. Sea trolling for salmon, we believe, should be encouraged, for it is the most promising avenue through which sea fishing for other varieties of fish may ho developed in the northern half of the state. T'he inauguration of salmon trolling a few years ago near Fort Bragg has resulted in fishing for other varieties of fish and it can bo confidently predicted that within a few years we will have other fisheries there of more importance than the salmon. EEL RIVER PROBLEMS Just as the catching of salmon of the sea has been an added drain on the Sac- ramento salmon, so is the recent rapid growth of salmon trolling near Fort Bragg an added drain on the Eel River salmon, and fish of that river are in need of additional pa'otection. This ocean catch is apparently having little effect on the run in tho Klamath River, which is more than one hundred miles to the north. It seems impossible to devise an open season for nets on Eel River Avhich will satisfy the needs of the sportsmen, the commercial fishermen and the salmon culturist, and at the same time properly conserve the two species of salmon and the steelheads which spawn in the river. The Quinnat salmon begin entering the river early in September, and as there is rarely sufficient water before November to permit them to get above the pools near the mouth, thes'e fish remain there ill tile frosji water i\nd aftm- a time become of little value for food, although they ai*e still of value for propagation purposes. If the netting season is opened early and closed early so as to let the latter part of the run asciuid the ri\or unhindered to the spawning beds, and so as to take these early salmon while they are still fit for food, it meets with the violent opposition of the sportsmen, who contend that it would ruin tlieii- steelliead lisliing which is carried on in the lower river before the winter rains. If the open season for nets is moved to a time sufficiently late to permit these salmon lying in the pools to ascend the river beyond the reach of the nets, too many spawning steelheads and silver salmon, which begin entering the river about the first of November, would be taken. The present netting season of October 8 to December 7, inclu- sive, was a compromise season designed to meet the conservation requirements of tho two species of salmon and the steel- head, and to partially satisfy the sports- men and commercial fishermen. This open season has not satisfied the sportsmen or tho comniercial fisherman, and it has not met the needs of the salmon culturists ; and, on account of the development of outside trolling, it does not meet the conservation needs of the Quinnat salmon. The season is not sufficiently early to take the first jmrt of llio run iiefore the tish become inferior for food purposes and it closes too late to let a sufficient number of fish reach the spawning beds up the river. On account of the deple- tion of the Sacramento run, salmon eggs can no longer be taken from that river to be used in stocking Eel River. If salmon culture is to be carried on in Eel River, the river must furnish its own eggs. Salmon racks can not be maintained in those parts of the river which are suitable for taking salmon for propagation pur- poses after the river is in flood, and it appears that the only feasible way in which eggs can be taken for this purpose is to permit the first of the run to ascend to tho salmon racks after tho first rise in the river, which is usually not suffi- cient to wash out the racks. If the net- ting season is placed sufficiently late to come after the first rise in the river and closes sufficiently early to avoid taking too many of the late running silver salmon — which date should not be later than De- cember 1 — tho season would hardly be long enough to iiiiiko netting ])rolit;ible. We see no good way of harmonizing these varied interests. Whatever is done it should be seen to that the conservation needs of the three species of fish involved get first consideration. CALIFORNIA FISH AND GAME. 59 NOTES FROM THE STATE FISHERIES LABORATORY.* Will F. Thompson, Editor. CHANGES IN THE PERSONNEL. Since the appearance of the last number of this magazine there have been several c-hangp.s in the staff engaged in fisheries research. Mr. John W. Rich, who has acted as field assistant in the albacore work at San Diego and San Pedro during the summer of 1920, has returned to Pomona College to resume his studies. Mr. O. E. Sette, who has been with the Commission for more than a year, has also returned to his college woric, having left for Stanford on Sep'tember 1. He was stationed at Monterey observing the sardine fishery during the fall and winter fishing seasons, leaving there to act as field assistant at San Pedro in the work on the albacore during the summer months. At Stanford he will take up the study of subjects bearing on fisheries research and will at the same time pre- pare for publication the sardine data which he has collected. The Commission is fortunate in being able to retain the interest and services of Mr. Sette, whose work has been of high order. To take the places of Mr. Sette and Mr. Rich, Mr. W. L. Scofield and Mr. Harlan B. Holmes have been added to the personnel of the laboratory, Mr. Scofield had been previously employed in research on the salmon and has been transferred to that on tbe sardine. He will be stationed at the Hopkins Marine Station in Monterey during the coming season, to carry forward the work already done by Mr. Sette. He is known to the readers of California Fish and Game for several contributions made in past issues. Mr. Holmes has been a student at the University of Oregon, at Eugene ; comes highly recommended, and with good training in biological work. He will be stationed at San Pedro, and will be engaged in the sardine work in company with Mr. Higgins. Mr. Thompson will remain in general charge of the work, with temporary head- quarters at Monterey. Mr. Higgins will remain at San Pedro. Professor Weymouth, who has been engaged for several months in research on the Pismo clam, leaves on Decem- ber 15 for Stanford University, where he will resume his teaching in physiology. He has one paper now in the hands ol the printer and another in the process of writing. His- work on the Pismo clam will prove of considerable value because of the great interest taken by the public in the preservation of that species, and because his work will prove of funda- mental importance in the study of other mollusks. THE SARDINE SEASON. The sardine season opens iuauspiciously this year, and it seems to be a serious question whether enough material will be obtained to complete our program of in- vestigation for this year. No sardines were being taken at San Pedro at the time this note was written — December 8 — and there was little hope held out by the cannerymeu that very extensive packing would be resumed at any near date. At Monterey a number of the canneries have ceased operations, but up to the present at least no difficulty has been experienced in obtaining sufficient fish for our pur- poses. What will happen in the future is not at present clear. There is no lack of fish at Monterey, and there is no reason t6 believe that they would be lacking at San Pedro if sought for. The reasons for the failure of the canneries to operate are given as a lack of orders, due very largely to the slump in export trade, and to the expectation of a falling market for sardines. The sardine investigation, however, will not suffer vitally, even though the program for this year be disrupted, as there are enough data on hand to take considerable time in handling and inter- preting. This program has been dealt with in the last issue of California Fish and Game (Volume 6, No. 4, page 180). ♦California State Fislieries Laboratory, Contribution No. 23. a) CALIFORNIA FISrr AND GAME. CONFERENCES ON THE SARDINE WORK. In order that the various assistants engaged iu Avork on the sardine may thoroughly understand the program, we have instituted a system of conferences, in which the men engaged at Monterey and San Pedro meet as often as necessary, or more often if possible. The last con- ference was on the tweuty-sixtli and twenty-seventh of November, when ^Ir. Thomp.son, Mr. Weymouth. .Mr. Sette. Mr. W. L. Scofield and Mr. Holmes were pres- ent. The purpose in this as on preceding occasions was to correlate the programs and to give everyone a Ihorough knowledge of them. These conferences are inevitable because of the necessity we are under of educat- ing the new assistants as they come, and of giving I hem an understanding of the fundamental reasons for the program we have adopted, if for no other cause. It is our hope that these assistants will be able — after the lapse of several years— to each take over entirely certain phases of the sardine or other problems, and to do this a thorough schooling is necessary. It has become obvious that a merely mechanical execution of duties by a more or less disinterested subordinate will not solve any of our fishery problems, and therefore we hope to give each woi'ker a show in the rewards and penalties which come to the research man. The inevitable period of training must include work under the senior assistants, but as fast as it is possible to place every investigator on a separate problem to make his own report tliis will be done, for it is recognized that no man works as well for another as for himself, and that there is no incentive comparable to that of professional success for which full credit is received. But until a thorough knowledge of the fundamentals is obtained such a course would be dis- astrous to any assistant, and hence the necessity of education. The more immediate aim is, however, to have a discussion of all that bears on our problems and to make sure that the investigations at Monterey and San Pedro supplement and parallel each other where necessary. These conferences already ' held have proved of the utmost value in formulating the programs of work, avoiding mistakes, and bringing to every- one's atteniiiiii tlie obsvi-NMl iiiMs made. — W. F. T. THE PROGRESS OF THE NEW LABORATORY. The building of the new laboratory at San Pedro has been definitely decided upon by the Commissioners, and the State Architect, Mr. McDougall, has the matter in hand. It is sincerely to be hoped that the building will be rushed, as we will face an embari'assing situation in the near future when the sardines begin to be taken at San Pedro, in that we will have to ask quarters from some cannery for our operations, the temi>erary labora- tory being too far removed. To those interested in the purjwses of the new laboratory the statement concern- ing them in tlie last issue of Cai.ii'(U{.m.\ Fish and (iJame, Volume G, No. 4, page 177, will be of value. THE HABITS OF SEA GULLS. It is not an uncommon thing to have the presence of small fish iu quantity regarded as the reason for the presence of great numbers of sea birds, especially sea gulls, at certain localities. Observa- tion at Monterey has shown, however, that the great flocks of sea gulls fre- quently seen there during the winter occasionally appear on the days following a severe blow or other weather disturb- ance. This has not been investigated enough, however, to justify a positive statement, yet is highly suggestive in throwing light uiion the belief mentioned as to their connection with the presence of young fish. The visits of the great flocks would seem to be due to the roiigh surf or wind on the outer coasts, when they are not present in both places in numbers during their migration. That sea gulls are very sensitive to the condition of the water is strongly implied by an observation we have made uix>n them at Monterey. This observation has been i'ei>eated so often by laboratory members working there as to be beyond doubt. The water off such a lee shore as at Monterey is frequently streaked with light and dark areas, the light areas CALIFORNIA Fli^II AND GAME. 61 being smoother and reflecting the sky more perfectly. These smooth light areas are always strictly avoided by the sea gulls (chiefly herring, western and glau- cous-winged) for some reason, the flocks of gulls at rest on the water being in- variably and sharply limited by the roughened dark water. This distribution of the flocks upon the water is for the purpose of resting, not feeding, and is invariable and exact. It is a most re- markable and strange fact. Whether the rough areas are caused by winds running counter to the currents or otherwise, the choice of such surfaces as resting places indicates unmistakably the sensitiveness of the gulls to the condition of the water, and thus throws some doubt upon the presence of food as the factor determining their presence. — W. F. T. A FURTHER NOTE ON THE MONTEREY GULLS. In the April, 1920, number (page 85) of California Fish and Game, in an article on the "Gulls in Monterey Bay," it is pointed out that these birds, although diurnal in habit, were on one occasion observed to be feeding at uight on sar- dines lost overboard while the lighters were being unloaded at the canneries. Such cases of night feeding are evidently not rare, for gulls in great numbers have been noticed recently on two occasions flying about the lighters in search of chance sardines dropped overboard. On one occasion the gulls were flying half an hour before daylight. The usual habit of the gulls is to spend the night on their roosting grounds, supposedly along the coast, and to appear suddenly at the can- neries in large numbers with a regularity as to time that suggests an alarm clock, the time being just before daylight and considerably before sunrise. On tht mornings when this sudden appearance was timed it was found to vary but a few minutes from the scheduled breakfasting hour for Monterey gulls. On one other occasion gulls were noticed in large num- bers at 10.30 i).m. (November 28) in bright moonlight flying about the sardine lighters. Fishermen and cannerymen say that the gulls have learned that the chances for a square meal are good when- ever the sardines are being delivered to the cannery, and that it is no uncommon sight on moonlight nights to see hundreds of gulls flying about on the outlook for stray sardines. Just what amount of fish a gull considers to be a square meal is a question. One gull has been observed to swallow four large sardines in rapid suc- cession and then fly off with ease. If the supply of sardines holds out more are swallowed until the bird is so weighted down that he is unable to fly, and must perforce walk or swim away to some quiet spot where the meal may be digested undisturbed. If confronted with the necessity of flying out of danger, the gull must lighten ship by disgorging his meal before taking to the air. Occasionally the sardine fisheiinen leave a lighter fuii ot fish uncovered and unguarded, in which ease gulls gather in the boat and eat until they are helpless. On the return of the fishermen the overloaded gulls allow themselves to be picked up and thrown overboard rather than disgorge away part of the feast. On one such occasion 05 gulls filled to capacity were counted as they were thrown into the air from a lighter and came down with a splasli into the water. After a few feeble attempts to rise from the water these contented gulls swam off sedately, all headed for a sheltered stretch of sunny beach. — AV. L. S. 62 CxM;Il''ORNIA FISII AND GAME. LIFE HISTORY NOTES. OPOSSUM KILLED ON MOUNT HAMILTON. Last night I killed a porch climber, in the shape of an opossum {Didelphis virginiana) , here on Mount Hamilton. A few years ago a number of these ani- mals were turned loose, or escaped, near San Jose, and they have since become established in the Santa Clara Valley. I was somewhat surprised, however, to find one at this distance from the original l)oint of importiition. Mount Hamilton is at the summit ol the range bounding the Santa Clara A'allcy on the east, and lies about thir- teen miles, in an air line, from San Jose. It is separated from the Santa Clara \'alloy by two deeply cut watersheds : Halls A'alley and Smith Creek. If the species keeps up its present rate of (ravel, it will be in the San Joaquin V'alley within a few years, and from there will doubtless spread rapidly over the state. From the havoc this one created in the grapevine that marked the end of his particular trail, his relatives will not be very welcome guests to the vineyardists and other fruit men of the state. — W. H. Wright, Mount Hamilton, California. THREE MOUNTAIN LION KITTENS CAPTURED. About September 1, 1920, reports came to the Fish and Game Commission that there were mountain lions in the vicinity of Cathcy Ranch, near Jerseydale, Mari- posa County. I was sent to hunt the lions. I arrived at Jerseydale on Sep- tember 10, and learned then that the lions had been heard screaming near the Cathey Ranch. Never having heard the so-called scream of the mountain lion, and, in fact, having found them to be an invariably silent animal, I was much disappointed with this report. However, I spent two days hunting in the vicinity of Jerseydale without finding any sign of lions. In the meantime, I telephoned to Ranger Malcolm McLeod and learned that cattle men had reported that they had seen some lion tracks several times on Owl Creek, near Devil's Gulch, eight miles northeast of Jersej^dale. On the evening of September 12, I moved my outfit to the Mariposa Ranger's Station and the next day, while Ranger McLeod packed my equipment to camp on Owl Creek, I hunted on the way over to the Fig. 2 7.

CALIFORNIA FISH AND GAME. 63 camp, then down the ridge on the east side of Owl Creek, and then to the east up Devil's Gulch and back to camp, I found old tracks of a female lion near the mouth of Owl Creek and in Devil's Gulch, but the indications were that the lioness had not been working these for several days. The next day, September 14, I started to hunt in the country west of Owl's Creek, and about 7 a.m. my dogs picked up the fresh trail of the lioness going east toward Owl Creek. After trailing about half a mile my silent trailer, Ely, who was about two hundred yards in the lead of Ranger, the hound, jumped the lioness, which was indicated by Ely's barking. The lioness ran down Owl Creek, going north for about a quarter of a mile, then treed in a live oak. I noticed that when Ranger arrived at the place where Ely found the lioness, he became confused foi a few moments before straightening out the trail, but I was taking a short cut to where Ely was barking "treed" so that at the time I did not learu the cause of Ranger's confusion. After shooting the lioness, the first thing that I noticed was that she had just been nursing kittens, as her breasts were still wet. I skinned the lioness and afterwards back-trailed her tracks over the course that the dogs had chased her. When 1 reached the place where Ely had found the lioness, I noticed her fresh tracks going on toward Owl Creek and returning again over the same course; this explained why the hound had gotten confused. The next thing was to find the kittens. After searching the brush and rocks for several minutes without success, and having in mind the track I had noticed going east from here and returning the same way, I decided that the kittens were somewhere farther east. Evidently, while the mother lion was nursing the kittens she heard the hound baying on her trail, about a quarter of a mile away, and left the kittens and back-trailed herself to meet the dog, but she was surprised by the silent dog, who was in the lead of the hound. Then she turned at right angles and led the dogs down the creek and away from the kittens. I now fol- lowed her tracks for about five hundred feet east and across Owl Creek to a bluff of rocks, where the dogs scented the kit- tens, which were hiding in the small holes among the rocks. Two of the kittens were in one place and the other was about twenty-flve feet from them in another hole. After considerable trouble I captured the kittens alive, and after taking off my shirt I carried them in it for about a mile to camp. From the camp I carried them in a barley sack for five miles to the Ranger's Station ixnO then from there by auto to the office of the Fish and Game Commission in San Francisco. The kittens were about six weeks old and were the size of an adult house cat. They weighed about eight pounds each and were twenty-six inches in length from tip to tip. The home of the lions was on a ledge about seventy-five feet from the water of Owl Creek and near the top of a bluff of rock. This ledge, which was about sixty feet above the base of the bluff, was about five feet wide and extended about thirty feet along the north side and the same approximate distance along the west side of the bluff. Although there was no cave or den large enough to shelter the mother lion, this was apparently the place where the kittens were born and where they had lived until they were captured; as there were numerous beds, l)otli on the north and west sides of the bluff, where the lioness had been lying on the ledge. The di-y grass and moss all along the ledge was well worn and trampled, probably by the kittens while playing. The small holes among the loose rocks behind and above the ledge had evidently provided hiding places for the kittens when dis- turbed.—Jay O. Bruce, Oalland, Cali- fornia. HOW MANY EGGS DOES A SALMON LAY? In the course of a study of King Sal- mon in Klamath River, it became desir- able to learn how many eggs the female produces. Thinking that it may be ol general interest, a table including the results of an examination of 30 indi- viduals is given, the specimens being selected from a larger number as fairly representing the average. Klamath salmon are somewhat smaller than those of the Sacramento, and it is (A CALIFORNIA FISH AND GAMI*:. possible tliat the foinalos prodnce fewor eggs. In a series of 3350 Klamath salmon the smallest female measured 20 inches and the largest 42. One cither smaller or larger is rarely found. The number of eggs here given were obtained not by actual count, but by weighing the ovaries, counting a small number of eggs, weighing the latter, and then calculating the entire number. Tests demonstrated that the method gave results accurate to 1 to 3 eggs in a 101). Ovaries from the same fish are not usually alike in size, the left being often somewhat larger than the right and containing as many as 200 or 300 more eggs. No very definite! relation is spon between size, weight, or age and the number of eggs, although it will be noted that fish in the fifth year are found amongst those having most eggs.

CALIFORNIA FISH AND GAME. 65 CONSERVATION IN OTHER STATES. SANCTUARY FOR WILD LIFE DEEDED TO LOUISIANA. A tract of land embracing 224,000 acres in Louisiana lias been set aside as a perpetual bird sanctuary, and second- arily as a refuge for game, thus bringing to fruition the project of Edward Avery .Mcllhcnny. On November 8, 1920, deeds were signed in the office of the State Conservation Commissioner which gave to the state in fee simple Marsh Island, 79,300 acres in extent, which was purchased and pre- sented by Mrs. Russell Sage; the Grand Chenier tract, 85,000 acres, purchased and presented by the Rockefeller Foundation, and the AVard-McIlhenny tract, 00,000 acres. Years ago the plan for this reservation was thought out by Mr. Mcllhenny, who first discussed the pi'oposition with a friend, Charles Willis Ward. Mr. Ward supported the idea and as a result the Ward-Mcllhenny tract was set aside as a wild life refuge. Mr. Mcllhenny, en- couraged in his plan to secure an adequate sanctuary for native and migratory birds, found a willing helper in Mrs. Sage. Soon afterwards he secured the appropria- tion from the Rockefeller Foundation and now the reservation is definitely assured to the state. The Marsh Island tract lies in the Gulf of Mexico, off the coast of Iberia, St. Mary and Vermillion parishes ; its eastern shores are famous a-s migratory bird haunts. The Grand Chenier tract is on the mainland and adjoins the Ward- Mcllhenny tract and is close to Marsh Island. The Marsh Island and Grand Chenier tracts have been under the care of Commissioner Alexander of the State of Louisiana for the past six years, and this supervision has been so successful that it was finally decided to trrn them over in fee simple to the state, along with the Ward-Mcllhenny tract. In the event of the discovery of any valuable ore or mineral, it is to be removed with the least possible disturb- ance to the wild life and the profits accrued must be used to further the pro- tection of it, and if more money is made from this source than is needed for its original purpose, it is to be devoted to education or public health in the state. VERMONT ESTABLISHES SANCTUARY FOR WATERFOWL. The \'ermout Fish and Game Commis- sion has secured an option upon a tract of 900 acres of marsh land at the mouth of the Lamoille River, on Lake Cham- plain, as a sanctuai-y for waterfowl in their trips north and south through this much traveled migration route. The area has been investigated as to its properties for feeding the birds by the U. S. Bureau of Biological Survey and is considered ideal. It is expected that enough revenue can be derived from the trapping privi- leges to pay the salary of a caretaker; for the region abounds in muskrats, skunks, and other fur-bearing animals. This step is the first of its kind taken in any of the northeastern states.— The Conservationist, June, 1920. VALUE OF PENNSYLVANIA'S ANNUAL KILL OF GAME. The State Game Commissioner of Penn- sylvania. .John M. Phillips, through the statistics of the State Commission, esti- mated that there were 6,'000,000 pounds of meat bagged as game last year which, at 20 cents a pound, would have a value of $1,200,000. Three thousand buck deer were killed and 472 black bear. Mr. Phillips estimates that next year there will be 4000 deer killed and that the total weight of the game killed, including all smaller game, will be at least 8,000,000 pounds, which, at 20 cents, would be ^l,000,Oi)0.— Field and Stream, Septem- l)er, 1920. QUEBEC LICENSES FUR DEALERS. Canada is following the United States in the effort to conserve fur-bearing mam- mals. Recently, the province of Quebec took over entire control of its fur trade. Fur traders must take out licenses and report monthly all furs bought. The government imposes a small royalty on all skins before they can be stamped, and no unstamped skin may be sold or shipped out of the province on penalty of confisca- tion and fine. Trapping out of season is to be controlled, for obviously no insi)ec- tor will stamp a skin which shows evi- dence of having been taken out of season. All shipments of skins not plainly marked on the outside will be confiscated and the sender fined. Thus, the poacher vpill be unable to market his illegally taken fur. GG CALIFORNIA FISH AND GAME. AUTOMOBILES CONFISCATED IN WISCONSIN. The state of Wisconsin lias a law which imposes on hnuting violators not only a $50 fine, but deprives these men of their guns, hunting licenses and automobiles. The confiscation of the automobile is a drastic and effective step, for it affords a stronger protection to the partridges and prairie chickens, which must be pro- tected against the onslaughts of those wlio previously have l)eeii willing to "take a chance." They are more apt to think now what it will mean if I hey are caught. THE SYSTEM OF CONSERVATION IN PENNSYLVANIA. In an article published' in the Bulletin of the American Game Protective As- sociation, Mr. Holland states that the basis of the game protective system adopted by I'enusylvauia is a combination of public slioofing grounds and game refuges. The first game preserve was established in Pennsylvania in 1905, and — quoting from Mr. llolhuurs report — "at the pres- ent time the state has twenty-four state game preserves, eighteen being on state owned forest lands and six on leased land that will eventually be owned by the state. These preserves are approximately nine miles in circumference and individu- ally contain from 1700 to 3200 acres. Around each preserve are from 3000 to 7000 acres of land that is public shooting ground, on which any man may go and shoot, provided he complies with the laws of state and nation." According to the state laws, one-half of the total acreage of the state can be utilized in this way. The game refuges have been placed as near as possible to the centers of popu- lation and in the center of state-owned forest lands, which during the open season constitute the public shooting ground. By this method the game is more readily pro- tected when out of season. The preserves can not be mistaken, for a wire stretched waist high surrounds it, and often as many as six refuge posters can be seen from one point along the reserve. Too, fire protection clearings surround each area. The average cost of establishing a refuge is $2,175, and the yearly cost i of maintiiiuing the preserves total about $1,174. Aside from the larger preserves, tliere are tlie auxiliary state game preserves, which "are tracts of land, generally of 250 acres or more. They are cared for by the state, but are owned by some individual or a group of several indiviiluals who are willing to donate or lease the land to tiie state as a game preserve for a period of ten or more years. A ])art of each tract is posted and cared fur by the state and the balance is used for public shooting. These I'eservations may consist of farm lands. The i)!aii ha.s been found very benelicial when' small game such as quail and rabbit are concerned." The system of protection practiced in Pennsylvania to assure to the sportsmen an abundant supply of game seems to be eminently successful, and by 1921 Penn- sylvania plans to have increased the number of her game preserves to forty.

The annual meeting of the Illinois Sportsmen's League was held at Belle- ville, III., on May 14, 1920, and quoting from the Illinois Sportsman, the official organ of the League, the program which they are to supiwrt follows. It will be noted that the organization still maintains that the Federal Migratory Bird Treaty Act does not give the middle West a fair deal so far us dui'k hunting is concerned: First — We are for the enactment of .iust and ecpiitable game and fish laws and the vigorous and imi)artial enforce- ment of the same. Second — We favor a program which will result in a better understanding between the farmer and sportsman. I'hird — We feel that the number of game and fish wardens is inadequate and stand for an increase, also insist that efficient service be given at all times. Fourth — Since the revenue from the sale of hunting and fishing licenses re- ceipts for fines, etc., more than pays the opei'ating exi)enses of the Illinois Divi- sion of (iame and Fish, we ask that this surplus be kei)t intact in a special fund to In used for the conservation of our wild life. Fifth — We stand for such an increase in game and fish as will furnish legiti- mate sport for every citizen. Sixth — We favor the establishment by the state of recreation grounds which will be open to the public at all times CALIFORNIA FISH AND GAME. 67 for either huntiug, lisliins, camping or other outdoor life sports. Sevoutli — We will give our support to the Illinois Natural History Survey and State Forester in the preliminary work now being done for the conservation of what is left of our natural forests. Eighth — We stand for a system of game refuges, and resting places for waterfowl; that is, in case public shoot- ing grounds are obtained by the state, certain portions thereof shall be set apart where! game can breed and raise its young without being molested by hunters, fol- lowing the Pennsylvania plan. Ninth — We stand for an extension of Ihe fish rescue work now being done by the state, and feel that this could bo made much more effective by the purchase or lease of certain lakes to be used for plac- ing the smaller fish taken from the shal- low bodies of water. When larger these fish could then be taken out and dis- tributed for stocking purposes. Tenth — We stand for a reduction in the bag and possession limits on all of our game birds and animals, this to be determined after a free discussion of the subject through the medium of this or- ganization. Eleventh — We stand for a change in the open season for the taking of our fur- bearing animals, preferably from No- vember 15 to February 15. Twelfth — We stand for a change in the open season on rabbits, preferably from November 10 to January 31 ; and in addition thereto believe a possession limit should be fixed. By delaying the opening of the rabbit season and mak- ing it the first day of the open season for quail, there is a general feeling among the true sportsmen that many quail will be saved. Thirteenth — Millions of dollars are being appropriated by the General As- sembly at each session for the good of the people, therefore we are of the opinion that the question of establishing state parks should be given some consideration along this line. Next year we propose asking for a liberal appropriation, and request the cooperation of the people in general in oI)tainiug the same. Fourteenth — We consider roving dogs and cats one of the greatest existing menaces to our wild game animals and birds during the breeding season, there- fore we favor the enactment of a law regulating the same. Fifteenth — Wie stand for an amendment to the existing laws whicli will give the state additional powers in dealing with the pollution of the rivers and other streams of our state causing the destruc- tion of our fish. Sixteenth— The Migratory Bird Treaty Act has been upheld by the United States Supreme Court, therefore, it is the su- preme law of the land, so the safe plan is to obey the same ; however, we still maintain that the Middle West states are entitled to a late winter season dur- ing February and March for the shooting of waterfowl and hope to convince the United States Bureau of Biological Sur- vey that this concession is due the sports- men of this section of our country. 68 CALIFOKNIA KlSll A N I ) (i \ M !•:.

Tlio California Fish and Game Commission liaving completed fifty years of service to the state in the administration and conservation of wild life resources, it seems fitting that a review of the problems of the past and their solution, together with an outline of the distinctive accom- plishments of one of the oldest state commissions, be published, to the end that the work of this Commission may be better understood and OOSG 74 CALIFORNIA FISH AND GAME. appreciated and that future activities may be governed by the successes ■ or failun^s of tlie past. Under the administration of Governor IF. TT. Ilaight, the legislature of 1870 established a Board of Fish Commissioners under "An act to provide for the restoration and preservation of fish in tlie waters of this state." The ])ill was approved on April 2, 1870, and Messrs. B. B. Redding, S. R. Throckmorton and J. D. Farwell were appointed as com- missioners. The former commissioner served the state for more than ten years. The United States Commission of Fish and Fisheries was not estab- lished until a year later. California tlius liad an organized tish com- mission nearly a year before the federal government took up similar Avork. The appropriation of $5,000 was largely used in importing new varieties of fish and in preserving those native fish which were recog- nized as valuable food fish. It was not until 1878 that the Commission was granted jurisdiction over game as well as fish. "The fii'st hatchery owned and operated by the state was situated on the grounds of the State University, in Berkeley. The Califoriua Acclimatization Society under the supervision of j\Ir. J. G. AVoodbury had been experimenting, and had made several successful hatches of eggs introduced from the eastern states. JNlr. Woodbury afterward became an assistant to Dr. Livingston Stone, at the Baird Hatchery, on the McCloud River, in 1872. when the first attempt was made to propa- gate the quinnat salmon in California. INTRODUCTION OF FOOD AND GAME FISHES. "The California Fisli Commission during the first decade of its existence introduced into the M^aters of this state a number of varieties of food and game fishes and the attending results are regarded as being among the greatest achievements in fishculture and acclimatization."* In the year 1872, an attempt was made to import from eastern states on a special arpiarium car the following: black bass, glass-eyed perch, yellow perch, catfish, tautogs, brook trout, salt water eels, lobsters and oysters. Unfortunately, this large shipment never reached California owing to a train wreck which was described in the official report as follows : "After leaving Omaha we stowed away as Avell as we could the immense amount of ice wo had on tlie car, and having regulated the temperature of all the tanlcs, and aerated the water all round, we made our tea and were sitting down to dinner, when suddenly there came a terrible crash, and tanks, ice, and everything in the car seemed to strike us in every direction. We were, every one of us, at once wedged in by the heavy weights upon us, so that we could not move or stir. A moment after, the car began to fill rapidly with water, the heavy weights upon us began to loosen, and, in some unaccountable way, we Avere washed out into the river. Swimming around our ear, we climbed up on one end of it, which wa.s still out of water, and looked around to see where we were. We found our car detached from the train, both couplings having parted. The tender was out of sight, and the upper end of our car resting on it. The engine Avas three-fourths under water, and one man in the engine ♦Sheblcv. W. H. : History of tlie Introduction of Food and Game Fishes into tlie VVaters of California. California Blue Book, 1911, pages 513-527. CALIFORNIA FISH AND GAME. 75 cab enifslic'd to death. Two men were float iiij;' down the swift eiirreiit in a drowning condition, and the balance of the train still stood on the track, with the forward car within a very few inches of the water's edge. The Westin,u'lious(> air-brako Iiad saved the train. If we had l)een with- out it, the destruction would have been fearful. ' ' One look was sufficient to show that the contents of the aquarium car were a total loss. No care or labor had been spared in bringing the fish to this point, and now. almost on the verge of success, everything was lost." (Bienn. Kept. Fish Comm., 1872-1873.) Undiscouraged by this loss the Commission asked Mr. Stone, who was in charge of the atiuarium car, to return East and obtain anew shipment. With the helji of the Ignited States Bureau of Fisheries, 40,000 shad were secured in the Hudson River. These fish arrived safely and w^ere planted in the Sacramento River at Tehama. m Fig. 28. Fisherman unloading catch of shad. Over a million and a half pounds of shad are taken annually in California. Tliey were first introduc:-d into the waters of the state by the State Fish Commission in 1871 and a second iilant was made in 1873. In the fall of 1872, a shipment of white fish eggs was secured in the East. These were hatched with success and 25,000 young white fish were planted in Clear Lake. During this period. Tahoe trout were introduced into several coastal lakes and streams. This constituted the first transplantation experiments. On June 12, 1874, another importation which included black bass, glass-eyed pereli, Scliuylkill catfish, horn-pouts, silver eels, eastern salmon, rock bass, tautogs, lobsters and salt water eels, were distributed to different lakes and streams of the state. The tautogs were placed in San Francisco Bay and the white fish in Tulare Lake. During the years LS7G-1877 an attempt was made to acclimatize the awa, a fish from Hawaii. Apparently, there were no results from the 2— «KSO 76 CALtroRNlA 1<'1SH AND GAME. plant made near Bridgeport, Solano County. Efforts to l)etter establish the white fish, shad, and other fishes were continued and additional importations Avere made. The striped bass was introduced in 1879 and the carp in 1880. The first published report on the edible fishes of the Pacific Coast appeared in 1881. In 1898, six fish hatcheries were in operation, as well as several egg- collecting' stations, and the 8issnn llatclifrv liad been enlarged to handle 1G,()()0,()(H) eggs at one time. In 1903-1904 additional attempts were made to introduce the greyling and the land-loeked salmon. Although fish were planted, no results' were obtained. At the same time four do/cn elegant quail imported from ^lexico were liberated, but soon disa])j)e'art'd. Chinese (piail were the subject of still another acclimatization failure.

A second plant was made in June, 1882, when about .300 were planted in Suisun Uay. The increase has been remarkable. Continued interest in the introduction of new food fishes led to the importation and planting in 1908 of crappie, blue-gilled sunfish, yellow perch and ring perch, making aiiout thirty different exotic species given a trial in the waters of the state. The above species have increased and are well established in the Sacramento and San Joaquin rivers. Attempted introduction of the ayu from Japan in 1920 met with failure. Enthusiasm over tlie golden trout of the southern lligli Sierra led to numy transplantations of this fish begiiniing in 1909 and 1910. As a result this species is now found 150 miles to the north of its original home in the head waters of the Kern River. Transplantations of striped bass were also attempted in more recent years. OUTSTANDING PROBLEMS AND ACHIEVEMENTS. The first outstanding problem confronting the Commission was that of the pollution of coastal streams by sawdust from the mills. It was found that the fish life in those streams into which the refuse from mills was poured soon became barren and demand was made for legislation to prevent further pollution. CALIFORNIA FISH AND GAME. 77 The need for fishways was apparent to tlie first board appointed and within a few years the building of them was made compulsory. The following quotation from the 1870-71 Biennial Report is of interest: "At one dam oji a tributary of the Truckee a mill owner consented to put in a fisliway, at the earnest solicitation of one of the commis- sioners, and to prevent the expenses of a suit. He said the law was an infringement of his rights, and when the legislature passed an act to compel him to spend money in such foolish l)usiness they should have appointed a schoolmaster to teach the trout how to use the contrivance ; he did not believe a tish could be coaxed to go near it. The next evening after the fisliway was placed in position the fish were passing it every few minutes; the mill owner became a convert to the practical use of fishways. He soon tore away the cheap and temporary affair built to comply with the law under compulsion, and has erected in its place a substantial ladder that will last for years." ^^h- .

The danger to young fish as a result of the shrimp fislieries early became an important problem of the Fish and Game Commission. Photographs by N. B. Scofield. The most important problem confronting the Commission in the years 1876 and 1877 was the decreasing run of salmon in the Sacramento and San Joaquin rivers. A demand for a closed season to limit the catch was made as a result of investigation. Interest in the salmon situation con- tinued for several years and statistics on canning operations and output were secured. Decimation of immature fish as a result of the practices of the Chinese shrimp fishermen, and the destruction of the sturgeon by the use of Chinese set lines next attracted the attention of the Commission and in 1885 a strengthening of the patrol service Avas ordered as was also the building of a patrol launch. By this time shad had become so numerous that a repeal of the closed season was recommended. Interest in salmon centered around the complaint that sea lions destroyed large numbers as they entered the Bay, and the building of the first large state salmon hatchery which was located on Hat Creek. An interesting political situation hindered the work of the Board during the years 1886 and 1888: "The work of the Commission was progressing very satisfactorily, until disturbed by the attempt on your part (the report was m^de to Hon. R. W. Waterman, then Governor of 78 CALIFORNIA FISH AND GAME. the State of California) to reorganize the Commission by placing thereon persons of your own selection. This attempted removal of the members of the Commission (Roiiticr and Harvey) discredited tlie acts of the Commission, destroyed public confidence in the legality of their official acts, and defeated all eit'(u-ts to an efficient discharge of their duties. That the legal status of the Board might be determined, Mr. J. D. Redding, who had been api)ointed l)y you to succeed Commissioner Routier, obtained the ])ermission of the Attorney General to bring an action in the name of the people to oust Mv. Routier, ])ut after suffering the action to remain in the courts for several months, lie caused it to be dismissed. Subsequently, flie State Board of Examiners, moved by the clamor of claimants who had furnislied sup])lies, or rendered services to the state, agreed that the (piestion as to who were entitled to act as the Fig. 31. A view of the Mount Shasta Hatchery taken about tlic year 1905. There are now six large hatchery buildings on the grounds. State Board of Fisli Commissioners should l)e submitted to the Attorney (Jeneral, and that the opinion of that officer should l)e biiuling upon the Board of Examiners until overruled by the courts."* The licensing of market fishermen as a means of controlling the salmon situation was begun on ^March 21, 1887. Although ai)puinted sohdy in the interest of preserving and increasing a fisli sui)ply, the Fish Commission early recognized the need for con- serving game, notably deer, as is evidenced by the following excerpt : "We recommend that the killing of deer be prohil)ited absolutely for the next two yeai-s, and also the having in possession of the skin of any deer for the same time. This is rendered necessary because of the great ♦Biennial Report of the State Board of Fish Cornmlssioners of the State of California, for tlio years 1886-1888. CALIFORNIA FISH AND GAME. 79 loss of these animals during the extremely severe weather of the last two winters, as well as their indiscriminate slaughter in some localities by hunters who defy the law with impunity. With these men, nothing save the heavy hand of the law can be made effective." (Biennial Report 1888-1890.) An appropriation of $2,000 first gave the impetus to the introduction of foreign game birds. In 1889 attempts were made to secure Oregon pheasants but actual stocking of the state did not begin until several years later. The screening of irrigation ditches now attracted attention for the first time and steps were taken to improve the existing situation. It was at this time also that various conflicting county laws relative to the mesh of salmon nets made the enforcement of the salmon laws very difficult. The sale of fish and game in San Francisco during the closed season became an important problem in the years 1891 and 1892. Under a system of cold storage it was possible for markets to hold fish and game, taken at a time when it was lawful, and to sell it during the closed season. It became apparent that unless some limitations were imposed j the closed seasons for fish and game would cease to accomplish any pur- ; pose, and recommendations were made accordingly. Demand was also made for an investigation of the marine fishes and the spawning and hatching of the same. By 1893, with an appropriation of about $20,000 and an income from fishermen 's licenses of about $4,000, the Commission was able to employ an attorney, and twenty-seven deputies who served without pay. Furthermore, the first compilation of the game laws of the state was made and printed. Sportsmen's clubs which had by this time begun to appear were encouraged. Of particular interest were the game statistics secured and published in the 1895-1896 Biennial Report. A table shows the receipts of game birds in the San Francisco and Los Angeles markets. The totals show 332,630 pounds of ducks, 175,444 pounds of geese and 37,880 pounds of California doves, pigeons and other game birds. The total valuation of the birds in the San Francisco and Los Angeles markets was $62,362.01. In 1897, attention was again directed toward the introduction of ring- necked pheasants and 323 were purchased in Oregon and liberated in five-pair lots. Satisfactory increase was reported. A year or two later about 250 more pheasants were purchased in Hongkong for seventy-five cents each and liberated in several different places in the state. Interest in commercial fisheries now developed to such a point that there was urgent demand for the al)atement of the destruction to young fish by Chinese shrimp fishermen on which agitation had begun as early as 1885. This came as a result of investigations made by an expert which consumed several months' time. Statistics showing the amounts of the different varieties of fish sold in the San Francisco markets were prepared in order to show the need for protective legislation. The sturgeon, once of no market value, was found to be the highest priced fish on the market and with the supply insufficient to meet the demands, in spite of protective laws. "As the hunting license law produced ample funds, and believing that the establishment of a State Game Farm where game birds could 3—9086 80 CALIFOKNIA FISH AND GAME. be raised in captivity and operated along the same lines as fish hatch- eries, would be in entire accord with the spirit of the law, which authorizes expenditures for the propagation and restoration of game, and being encouraged by the example of other 'states, it was decided to undertake the establishment of one in California. Negotiations for services Avere entered into with several men who had had experience on game farms in eastern states, also with ]\Ir. J. R. Argabrite, a resident of California, who was a successful raiser of pheasants in Ventura County. This resulted in engaging the services of Mr. Argabrite in September, 1908. He was immediately detailed to examine and report on a number of different locations that had been offered for the estab- FiG. 32.

Kpt. 1!)U).) A location was finally selected one mile south of Hayward, Alameda County, and a lease executed in November, 1908. A stock of pheasants was immediately secured together with four dozen Hungarian partridges. During the ten years of its existence the game farm reared and distributed several thousand pheasants, many quail and some wild turkeys. The expense of the farm seemed to be so out of proportion to the results obtained and the location so unfavorable for game propagation that the farm was finally abandoned in the fall of 1918. In the last years of its existence it was used more largely as an experiment station to determine the possi- bility of breeding different species of game birds and mammals. CALIFORNIA FISH AND GAME. 81 When the game farm was first established there were a number of experiments made in the transplanting of native species. In 1908 and 1909, about three thousand quail were trapped and distributed in various sections of the state. About one thousand five hundred of this number were quail trapped in Lower California and liberated near Los Angeles. The incentive for these plants had its source in the mistaken idea that quail were decreasing because of inbreeding. During the period 1910-1912, due to the concerted effort of Commis- sioner Newbert, public interest in fish and game conservation was aroused by directing and otherwise aiding in the formation of a repre- sentative protective organization, with a membership of over 16,000 sportsmen scattered through every county in the state. Each county sent representatives to Sacramento in order to aid in the formulation of the game laws so that the laws would be as fair to the people of the state as it was possible to make them. The organization, however, was short lived. In 1912, Charles L. Gilmore was appointed by the Commission to make a stream surve.y, all of the available data to be recorded on maps together with fish distribution in proper position with reference to the locality of the actual plant. The best available s'ources of information and of sta- tistical data were consulted and an intensive study made. Beginning in 1913, the Fish and Game Commission started emphasiz- ing scientific investigation of the many problems relating to fish and game. For these investigations experts from the State University and from Stanford University were secured. Professor Charles II. Gilbert undertook an inquiry into the life history of salmon and trout. Study of the life, abundance and conditions most favorable to the maintenance of our edible crabs was undertaken by Professor Frank W. Weymouth. A study of the clams of California was made by Harold Heath and one on abalones by Chas. L. Edwards. Complaint of the devastation caused by meadowlaiks and other nongame birds led to the study of the rela- tion of birds to agriculture by H. C. Bryant. At this time also. Miss Gretchen Libby was secured to conduct an educational campaign regard- ing wild Fife andwild life conservation in the schcols of the state. Prank C. Clarke undertook an investigation of the deer problem and published a report. ■ On August 10, 1913, the employees of the Commission were included in the classified list of state employees under civil service. In this year also administrative divisions were established under the charge of branch offices at Sacramento, Los Angeles and Fresno. Beginning in 1914, emphasis was placed on education and publicity, a separate department being inaugurated. Conservation work in the schools and in the summer resorts was undertaken, as well as the publi- cation of a quarterly, California Fish and Game, with the motto, "Conservation Through Education." In 1017, in anticipation of an income from a newly established fisheries tax, scientific investigation of problems connected with the rapidly growing fisheries of the state were begun with the ultimate establishment of a State Fisheries Laboratory at San Pedro under the direction of Mr. W. F. Thompson. A patrol boat suitable for use in scientific work was built in 1918. A system of recording the catch of fish in order to furnish statistics of fluctuation and overfishing was also begun. 82 CALIFORNIA FISH AND GAME. The ofanie refuge as a means of game conservation came to the fore about 1909 hut it was 1915 before extensive areas were set aside. In 1917. sixteen large areas were added making a total when the national paries and monuments are added of ai)out 3,000.000 acres. Fig. 33. The old Talioe llatchciy as it appeared in 1906.

CALIFORNIA FISH AND GAME. 83 In 1920, the Commission was operating sixteen fish hatcheries and six egg-coHeetino' stations. The output in tront for the two-year period ending June 30, 11)20, amounted to 31,000,000. In addition 29,000,000 Chinook sahnon were hatched and distributed. Thus we find at the end of the fifty-year period that continued emphasis is being placed on fish propagation with attendant spectacular results. PERSONNEL. A succession of interested and discerning commissioners backed by a long list of faithful employees have combined to make a splendid working organization. The policy pursued by each newly appointed Commis- sion of retaining employees instead of using political power to oust them has allowed certain policies to be continued through a term of years, without change and with correspondingly favorable results. The present liead of the Fishculture Department, W. H. Shebley, and his assistant, E. W. Hunt, have served the Commisison continuously for thirty-five and thirty-two years respectively. The list of chief deputies and executive officers is very short considering the political changes during fifty years. The list on page 84 will furnish some idea of the men appointed by various Governors, as Fish and Game Commissioners. ChJef Deputies and Executive Officers. John P. Batacock December, lS92-Oclober 15, 1901 Clias. A. Vogelsang- — October 15, 1901-August 15, 1910 John P. Babcock August 15, 1910-November 29, 1911 Ernest Schaeffle November 29, 1911-September, 1916 Carl Westerfeld — December 8, 1916-April 28, 1920 Chas. A. Vogelsang April 28, 1920 — CONSTRUCTIVE LEGISLATION AND COURT DECISIONS. A number of court decisions have formed the ground work for the successful administration of fish and game laws, not only in California but in otlier states. The more outstanding cases have had to do with pollution, transportation and sale of fish and game. Brief statements regarding the more important ones follow: It was in 1893 that the Supreme Court handed down a very important decision relative to the sale of venison. In the case of Simon Maier, the law making the possession of venison illegal during the closed season was upheld even though the deer might have been killed without the state. Hide hunters were most active about 1880 when thousands of deer hides were shipped annually from Sacramento Valley towns, but a final cleanup of offenders did not come until 1893, when arrests were made in San Francisco and an important case won. Thereafter, violations of the deer law were less flagrant. Several important game cases helped put a stop to illegal sale of game in the markets. A test case of the law fixing a limit on the number of quail, ducks, doves and other game liirds that one person may possess during one calendar day was decided in favor of the people, and market men of San Francisco were forced to limit their supply to a single bag limit. Similar cases carried to the Supreme Court were decided favor- ably. Also the law prohibiting the sale of quail was upheld in the Supreme Court. Inspection of express shipments was begun in an effort to stop illicit shipping of game. 84 CALIFORNIA FISH AND GAME. , n o o o> 03 ci r^ 00 « ^ u> cc hi z o cfl -• "5 •a bn II 3 ,u! a ■n o o I -s n M > § to S3 i o o .a 03 a> o O 3 a o O •q . « .2 a S3 ^ 4^ 3 o a o a •a a a 03 03 ^ t-i tD tD be V 03 03 03 g a P.

For the two years end- ing September 1, 1898, nineteen cases where explosives had been used were prosecuted. Owing to the efforts of the Commission a hunting license law was enacted in 1907, but the angler's license law" was not enacted until 1913. The hunting license law met the approval of all those interested in the preservation of game and provided funds for a $20 bounty on mountain lions, after November, 1907. In 1897, a case of importance which was brought before the courts was that against the Truekee Lumber Company for dumping sawdust in the Truekee River. The company maintained that the state had a right to protect fish only in navigable waters and that in all other waters the right is exclusively in the riparian proprietor. The Supreme Court ruled that the right to take fish extends to all waters and that therefore the title remains in the government. Also that the waters of the state furnish passageway for the fish and that they can not be subjected to private ownership. Further that the owner does not control all of the fish in the stream except as he reduces them to actual possession and that he can not kill or obstruct the free passage of those not taken. Proper control of the transportation of game was attained by winning two important cases, one of which put the game transfer companies out of business and the other sustained the law prohibiting the use of parcel post in the shipment of game. "For a number of years prior to 1913, there was an organized effort on the part of certain connnission merchants in San Francisco to evade the limit law on ducks and to that end transfer companies were formed, which, while endeavoring to act as such, were, in fact, subterfuges of the several commission houses ; for the reason that a transfer company is allowed to have in its possession more than the limit of ducks in one day, for the purpose of transportation only. When the Commission dis- covered this fact, all the ducks in the possession of the so-called transfer companies were seized. Thereafter, an action was brought in the Superior Court to restrain the Commission from seizing the ducks, so shipped, and for $5,000 damages. Judgment was rendered in favor of the Commission and against the plaintiff, for costs. Since the rendering of this decree, these so-called transfer companies have entirely gone out of business and it has reduced the unlawful distribution of ducks to less than one-half." (Bienn. Kept. 1914.) The first legislation regarding the nonsale of game was brought before the people of California in 1893, when the market sale of deer was pro- hibited. In 1901, quail were taken from the market. But a crisis was reached when, in 1913, along with many other bills relating to fish and game, there was introduced into the legislature what has since been known as the "Flint-Cary bill," prohibiting the sale of wild ducks and wild pigeons, in addition to the wild game the sale of which had been previously forbidden. 86 CALIFORNIA FISII AND GAME. This bill was passed by both houses and signed by the Governor, but those who had failed to pr(n'eiit its passage, namely, the Northern (Cali- fornia Hotel Men's Association and others, got np a referendnin peti- tion, which led to the setting aside of the l)ill until the general election, November 3, 1914. Tiie \:\\y failed of j)assage in the November election, but a few years afterwai'ds the federal law was passed which ])]-ohil)its the market sale of any migratory game which accomplished the desired result. In July 1914, on account of the decision that the Districting Act of 1913 was faulty, it became necessary to revise the act and to change many of the laws on the statutes. This was done at the 1915 session of the legislature. On September 11, 1917, Frank Phoedovius was arrested in San Mateo County for shipping deer meat by parcel post. Tie was tried and con- victed and sentenced to pay a fine of $25 or be imprisoned in the county jail until said sentence was satisfied, in proportion to one day's imprison- ment for every dollar of said fine. The fact that the postal laws pre- vented inspection of any packages shipped by parcel post had been taken advantage of by the market hunters and fishermen. The decision in this case took from them the last avenue through which the game and fish of the state could be unlawfully exploited. CONCLUSION. These features of the work of the Commission have been selected more or less at random and doubtless there are many other accomplishments Avhich deserve recognition. Such have been left out for the sake of brevity. The above achievements have of course been accompanied with many discouragements and some failures, but the latter are overshadowed by these notable successes. With such achievements as a backgi'onnd the future should yield a rich harvest of new attainments. CALIFORNIA FISH AND GAME. 87 PUBLICATIONS OF THE CALIFORNIA FISH AND GAME COMMISSION, 1870-1920. Compiled by Harold C. Bryant. INTRODUCTION. A test of the efficiency of any organization whose function it is to administer natural resources is to be found in the actual publislied results of scientific research. Certainly, a Fish and Game Commission is not functioning correctly if legislation and current activities are not based on the carefully ascertained facts secured as a result of scientific inquiry. That the California Fish and Game Commission has not been remiss in this regard is evidenced by the following list of publications. Although compiled largely as an aid to those making use of published articles on the fish and game of this state, the list should bring force- fully to the minds of all readers the outstanding features in the work and accomplishments of the Commission during the fifty years of its existence. The list is as near complete as it was possible to make it. As the files of the Commission were destroyed in the San Francisco fire of 1906, reference has been made to the files of the State Library and the University of California Library, as well as to files of the Fishcul-. tural Department. All of the publications listed with but one or two exceptions have been published by the State Department of Printing at Sacramento. In some instances new series of bulletins have been started under different administrations without due regard to previous series. These have accordingly been designated as new series, to avoid duplication of bulletin numbers, although this designation does not appear on the bulletins themselves. The serial publications of the Commission have been: (1) biennial reports (a report to the Governor required by law) ; (2) California fish and game laws (a compilation of the laws relating to fish and game for the use of deputies) ; (3) abstracts of California fish and game laws (cards giving a summary of the open seasons, bag limits and other regulations) ; (4) fish bulletins (publications giving the results of scien- tific investigations) ; (5) game bulletins (publications giving the results of scientific investigations) ; (6) teachers' bulletins (a series designed for the use of teachers in the public schools) ; (7) miscellaneous bulle- tins (miscellaneous reports on the work and accomplishments of the Commission and publications appearing irregularly) ; (8) California Fish and Game (a quarterly magazine with the motto "Conservation Through Education") ; (9) reprints and separates. 4— yoSG 88 CALIFOHXIA FISH .VXD GAME.

By J. S. Hunter. The one predatory animal for which practically no good can be said is the mountain lion. This animal without dou])t kills more deer in California than are killed by all of the hunters. They also destroy a great many domestic animals. The actual meat value of the game and domestic animals destroyed by lions is impossible to estimate but it is safe to say that it runs into thousands of dollars. During the many years that the Fish and Game Commission has been paying a bounty for every lion killed, hundreds have been taken, and up to January 1, 1920, $65,550 had been paid out in bounties. In August, 1917. the amount paid for the killing of a female lion was increased from $20 to $30. Between that date and January, 1920, females to the number of 218 were sent in. Many requests have been made to the Commission that the bounty be still further increased. It is doul)tful whether there would be any increase in the number killed even though the bounty were doubled. Most lions are killed either for the sport or on account of their destroying stock. The bounty is not the chief factor, but only an incident. In general as soon as a lion is reported there is a small army of hunters scouring the country, all anxious to boast of having killed a lion. Contrar}^ to the general opinion lions are not abundant in any part of the state. From the accompanying table it will be noted that Hum- boldt County leads with a total of 564 killed during twelve years time. The animal has been so reduced in that county that the kill has dropped from 113 in 1908 to 8 in 1919. In Shasta County, the next on the list, the kill has been less than oneJialf, 261 killed during the same period. Here, however, the animals have apparently not been reduced to the same extent as the kill in 1919 was approximately the same as in 1908. In Trinity County 260 have been killed ; last year only 14 as against 18 in 1908. In Siskiyou County none were killed last year; but in 1908 the number totaled 31 and in the twelve-year period 241. From this it would seem that lions in Siskiyou County are greatly reduced if not practically exterminated. Only one other county, Mendocino, reports more than 200 the first twelve years. In that county 219 have been killed; the number (22) taken in 1919 is just one-half those killed in 1908. Tehama County killed three during 1919, as against 31 in 1908, making a total of 159 in twelve years. It is evident from the above figures that California lions are being slowly reduced in number and that the animals killed approximately if not entirely exceed the natural increase. If this is true we can form a very good idea as to the number of lions in the state. Forty-two per cent of the lions sent in for bounty are females. The female lion does not bring forth a litter every year but only every other year. Sometimes three kittens are bom but the usual number is two. This would make the kill of 243 in 1919 the offspring of 243 females or 42 per cent of the total number of lions in the state. This calculation would give a lion population in California of al)out 575, which we believe is somewhere near the actual number. 100 CALIFORNLV FISH AND GAME. This niim])or of lions can do an enormous amount of damage to the d6er. The minimum estimate of the number of deer killed by a sin<:le lion eaeli year lias been placed at fifty-two. Five hundred seventy-five lions will kill at least .'50,000 deer during the year if deer are availal)le and deer are common in every part of the state where li<»iis are found. The California Fish and (lame Coiinnissioii has determined to make every effort to still further reduce the number of lions. Knowing the increase of hunters and the ease with which hunters can reach what were formerly the most inaccessible places.it will be necessary to stop Fic. 35. Jay I'.ruce, state lii)n limitor, and his clogs. The Fish and Game Commission hires Mr. Bruce to cut down the rlumber of mountain lions in the state game refuges. the heavy natural drain on tlie d(>er supply caused by this animal. On this account an expert lion hunter has been employed. This man, Jay C Bruce, is one of the best lion hunters in the country. In fact, the atten- tion of the Commission was called to Mr. Bruce because of the many lions which he sent in for bounty from Mariposa County. ^Ir. Bruce was born in IMariposa County and spent a great deal of his time in the mountains becoming thoroughlj^ familiar with the habits of the animals of the forest. On account of an injury to his left hand CALIFORNIA FISH AND GAME. 101 while working in a lumber mill he was forced to secure other employment and turned to that line of work for which his life long training had fitted him. On account of the bounty paid for the killing of lions he devoted considerable time to trailing them with dogs and was very successful. His success as a lion hunter is due to the fact that he has made a study of the habits of the California lion and knows their habits thoroughly ; also to the fact that he is an expert dog trainer and has his dogs trained so that they will follow only the tracks of either a bobcat or a lion and of no other animal. On account of this he can work without difficulty where deer are abundant. These dogs will never take the trail of a deer. Since Mr. Bruce has been employed by the Commission he has worked chiefly in the game refuges and has made an excellent record. His greatest kill during any one month has been eight lions. Because of the success of the attempt to control the mountain lion it is the intention of the Commission to keep Mr. Bruce employed and later, perhaps, to employ other lion hunters.

We were at tlie dinner ta])le Avlien a Frenchman rushed in wavinp^ liis arras and talkin<,' at the top of his voice a stream like a liigh pressure fire hose. Lunch was tinislied in an uproar. Finally I found there had been no murdei- I)ut that a wild hoar had been seen at the edge of town. Flaml)o. the reliable old huntinu; hound, was out callinor on his friends so the gray haired patrone of the hotel stepped to the door and wound several blasts on a cow-horn. Flambo arrived on the lope and I sup- posed we were ready to start, but not so. We talked about it for another hour and had other glasses of wine all round. By this time other cow- horns were tooting and other mighty hunters arrived at the hotel with shotguns and game bags large enough to carrv the tail of a good sized ])oar. Finally eight of us were ready to start witli seven shotguns, four game bags, one hound and five cow-horns. So we had another glass of wine, talked some more and started for the communal forest about a mile from town. We followed a trail through thick growth along a stream where l)oars might besport themselves on sunny afternoons, the dog on a string that choked him till his tongue hung out, high tension jabber from all the men and every few minutes some imbecile would let out a blast on his horn for the purpose of adding to the general hilarity and scaring all the game for miles around. Wooden shoes clattered and animated conversation continued till the dog took the trail and then the racket increased instead of subsiding. We trailed the boar to a thicket and separated to surround him. Guns were unlimbered, conversation increased if possible, the dog wa.s loosed so he could breathe again and chase the boar out of the thicket but we found the boar was not in the thicket. Instead of sitting down and waiting to be surrounded when he heard the uproar the fool boar had wandei-ed off somewhere else so after a half hour's conversation about it we trailed him to the next thicket and repeated the same ])erfoi-mance. This continued all aftci'iioon and furnished ainimniitiou foi- the most exciting conversation but no boar. I came to realize that conversation was the chief object of the occasion. If we cpiietly sui"rounded the l)oar someone might kill him and then there would l)e no l)oar to hunt and talk about another day. My trouble was that I had gone out on a talking expedition without sufficient knowledge of the language so I took a walk alone to look over the country. Toward evening I had no difficulty in finding the hunters for I could hear the din for a couple of miles. We returned to the hotel having been wdthout wine for more than three hours. Half the village gathered in the hotel kitchen to talk about the hunt. At odd times we had some supper and I retired at eleven o'clock with the talk still running at fever heat. CALIFORNIA FISH AND GAME. 103 THE ABUNDANCE OF YOUNG PISMO CLAMS.* By Frank W. Weymouth, Stanford University. While collecting data for the study of the life history of the Pismo clam some interesting facts regarding the abundance and fluctuations in number of the young have come to light. During the spring and summer of 1919 the young of the preceding summer (1918) were difficult to obtain. In the fall of 1919 the young of that summer were first observed and have been noted in almost incredible numbers up to the present time. During the present fall (1920) a special search for the young of the current year has been made but only a few specimens have been obtained, indicating an even poorer spawning year than that of 1918. Before comparing in more detail the relative success of the three spawning seasons it may be well to give some idea of the habits of the young and the methods used in estimating their numbers. The young of the Pismo clam is found for the first three years chiefly between tides where it is easly studied. At low tide on the long Pismo-Oceano beach the firm wet sand which proves so good a road for automobiles is the zone of their greatest abundance and many can be turned up by digging down an inch or so with the fingers. A more striking idea of their numbers may sometime? be gained after an unusually low tide when this area has been left dry for some time. A tiny hole then often appears above the siphon or "neck" of each clam and at times due, apparently, to their movements a little mound is raised above . each animal. A vieM' of the beach at such a time is shown in Figure 36 and gives a vivid idea of the abundance of the young clams. An actual count of the numbers of young clams has been made at intervals in the following way : A shallow trench the width of a clam fork (9| inches) was dug across the entire wet beach and into the water at low tide (see Fig 37). All the clams found were sorted into age groups, as is easily done by differences of size in the young, and the number of each age' counted. They were found chiefly in a narrow zone some 20 to 30 yards wide corresponding to the roughened areas shown in the photograph ; above and below this scattering clams were found, but more than nine-tenths of the young were concentrated here. The actual counts made over a period of about a year and a half range from 1294 to 774. The young spawned in 1919 are, in all collections since their appear- ance, the most numerous, forming never less than 98 per cent of the total. Those of the previous year (1918) form from 0.88 per cent to .1.32 per cent, while in the two last counts in which the young of the current year (1920) are represented they form only one-fourth of one per cent. Other years, when the young were as abundant as in 1919, are reported by the diggers but seem to come several seasons apart. The total numbers of young occurring in the entire beach as the result of a successful season such as 1919 is amazing. The productive area of the Pismo-Oceano beach is some eight miles in length; of this the northern third is by far the most thickly populated. The count was not made at the northern end, but near the middle of the beach *California State Fisheries Laboratory, contribution No. 23. 104 CALIFORNIA FISH AND GAME. where the conditions more nearly represent a fair average. A conser- vative f'stiiiiatc of tlio total number mi^-Iit l)e gained by considei'iim' six miles of beach with the numbers found in the region examined. Taking an average of the more recent counts when 800 young of 1919 were present in a cross section of the beach 9^ inches Avide, a mile would contain 5,150.000 and six miles 30,900,000 clams. Other earlier counts would bring the total to 45,000,000. To this must be added the beach at Morro which, though not examined for this purpose, probably would double the present estimate. Fig. 36. View taken on Pismo beacli at low tide. Note pits and raised areas mentioned in the text; every pit or mound indi- c.-ites a clam and there are other clams that show neither. Photograph by F. W. Weymouth. Several important lessons should be drawn from this. When condi- tions are favorable the young of the Pismo clam are produced and given a foothold in such enormous numbers that the supply of adults should be secure if the young have a fair show. But the "if" should not be forgotten. Large numbers die from natural causes over which we have no control. But there are losses which could be prevented. In order to protect the Pismo clam, laws setting a size limit of 4f inches and a bag limit of 36 have been enacted. Many tourists and summer visitors, however, thoughtlessly dig these young that are so easily found CALIFORNIA FISH AND GAME. 105 between tides and because they are so small take hundreds to furnish a single meal. The digging of an equal number of those of legal size would violate the bag limit but in realty would do less harm, as most of those which have reached a length of 4f inches have spawned, thus leaving behind them clams to fill their places. It is unfortunately true that other people including residents with undoubted knowledge of the law also take these young in large numbers. Unless these violations of a wise and necessary law are stopped by the cooperation of all interested people, their disastrous effects must soon be felt. All local residents that value the Pismo clam as a peculiar and distinctive local product should take every means possible to protect the young and to inform tourists and visitors of the need for its protection. With proper pro- tection there is no reason why the Pismo clam should not remain a local Fig. -37. Portion of treiicli made in countina; young I'isnin clams.

Weymouth. asset— with continued destruction of young before they have spawned as well as the taking of the adults of legal size, it will only be a question of time when this fine clam will be practically exterminated. Another phase of the scientific work of the Fish and Game Commis- sion is apparent here. The effect of an unusually good spawning year upon a fishery such as the sardine was discussed in the January issue.* Because of the ease with wliich the young of this clam may be studied we have here an even more striking example of such a successful spawn- ing year in the season of 1919 which exceeds that of 1918 by seventy- five to one hundred times and that of 1920 by about four hundred times. According to reports the last season producing comparable numbers was four or five years ago. Evidently, for a number of years the clams *See "The Future of the Sai-dine," by Will P. Thompson, California Fish and Game, Vol. 7, pages 38-41. 106 CALIFORNIA FISH AND GAME. spawned in 1919 will form the dominant class and when they reach legal size thoi'e will he an iinnsnally fjood yield of eliiins. With a ('oini)lete knowiedtre of the a^-e reaclu'd and the rate of <;ro\vth of tlie I'ismo clam it wonld be possible to predict the future yield quite accurately from a yearly examination of the younfj such as here described.

QUARTER-OILS OR HALF-POUND OVALS.- Hy WiiL F. 'I'lio.Mi'soN. (California State Fisheries Laboratory, oontriliution No. 24.) One of the great problems which presents itself to the student of fisheries, that of the effect of occasional i-uccessful si)avvning years, was considered in relation to the sardine, in the last issue of Cali- fornia Fish and Game. It was shown that the presence or absence of such great changes can be ascertained, and that such knowledge is most necessary to the proper understanding and prosperity of our greatest fishery. ^Moreover, the fascinating possibility that such a great change might be prophesied was held forth. In this article another prolilem, equally great and ecpially intei'esting is dealt with, and its close relationship to the great problems of biology is remarked upon. Our sardine fishery, important as it is, has for the most part arisen within the last few years. At first an adjunct to that very recent one for the albacore, it ha,s noAV reversed this relationship, and whereas once in Southern California' the sardine was canned between albacore seasons, now the albacore and tuna are 'canned between sardine seasons. Such a limited experience has not until the present brought into question some of the fundamental facts u])on which canning opera- tions must rest. One of these is the subject of this paper ; namely, the size of sardine which a cannerv at Monterey, or a cannery at San Diego may expect to |)aek in the future. AVill it can "(luarter-oils," or "half-pound ovals" — the small fish or the large? Experience thus far seems to indicate that the small fish will pre- dominate to the south, the la''ge fish to the north, that San Diego will be best for "quarter-oils" and Monterey for the larger sizes. This is an important fact — if fact it is— and if brief experience indicates the truth. Such a condition is liighly i)robable, as any fisheries expert should know, for there are several fisheri(^s in which such a distribution of sizes holds permanently. The cousin of tlie sardine— the Atlantic herring — has just such a distribution in the North Sea and along the Norwegian coast, and the Pacific herring may have the same along our own shores. The albacore of California has a similar difference in size between its southern and northern representatives. Yet we have had such a brief experience with the sardine of our waters that the seem- ing difference may be due merely to the passing at different times of dominating age classes such as we dealt with in the last article. Not until we know the real cause, or positive facts which will limit our * "Quarter-oils" are the sardines packed in small square cans in oil.

So little attention has been given to the basic laws of fishery science that what we have to say about the (|uestion is necessarily speculative — but will, we hope, demonstrate the possibilities and the fascination of its solution. Inevitably the theory most popular and most readily advanced to explain the differences in sizes is that of inigrafion. According to this the sardines move towards the north as they grow older, and then the eggs are carried to the south by currents, so that there is a manner of eddy in existence. Perhaps some people would unhesitatingly assert that sardines hatch from the egg near San Diego and reach the State of Washington before they die. The more moderate minded would pos- sibly confine themselves to a migration of the distance between San Diego and San Pedro. But it is worthy of note that either is a pure assumption, which must bear critical examination no matter what the degree of limitation imposed upon the theory. It presupposes, indeed, that the sardine population is a homogeneous one, necessarily of the same race or breed from north to south. The proof of the existence of peculiarities in the fish from San Diego which are not present in the fish from San Pedro or Monterey, even though these peculiarities are not racial nor inheritable, would decidedly limit the theory of migration, if it did not eliminate it. The existence of such local "races" of herrings has been conclusively shown, to the great damage of the theory in the case, but it persists in modified form — that the herring of each local race migrate in the same way as all were sup- posed to do. And so it will doubtless be in the case of the sardine, the proof of the existence of local races will simply confine within smaller limits the ever-present theory. Nevertheless, it is of the greatest impor- tance to distinguish local races of the sardine if possible. But aside from this attempt to confine within logical bounds a theory tending to be adopted in a most unscientific way, there should also be examined certain fundamental facts which may bear on the question. Thus he supposed migration must vary enormously from year to year to account for the great schools which appear off Alaska, if indeed it could be shown that such schools could be drawn from the south with- out producing there a great temporary lack easily noticeable. And, again, it is an open question whether there is anything approaching the requisite permanent lack of adults in the south or the lack of young in the north. It may be totally unnecessary to postulate a migration, as a matter of fact, for sufficient adults or young may be present every- where throughout the range of the species. Moreover, when one con- siders the vast numbers of eggs laid by fishes, like to the seeds of trees, and the few which must come to maturity from all that horde, it would seem perfectly obvious that even a slight difference in the surrounding conditions would cause great changas in the numbers which reach the various sizes, or stages of growth. And in this last possibility, we come to the second — perhaps more logical theory — that differences in pro- portion of adults and 3'oung may be due to the differences in living conditions. For living conditions must play among fish much the same part that they do among the human kind. Scientists have shown that in barbaric races of man the prevalence of disease, hunger, and war tend to reduce 108 CALIFORNIA FISH AND GAMfe. the chances of survival and render the older inhabitants relatively fewer than in quieter eomniuijities. So Ave might expect among fishes, tliat if other animals prej'ed on the earlier ages, the proportion of adults would bn much reduced. And it is perhaps a significant fact that the sardines farthest south live in w^aters which are populated with many- active and predacious enemies, particularly of the mackerel type, such as the tuna and the albacore. The contrast between north and south is, indeed, obvious to anyone who has fished in both waters. What more natural, then, than the failure of the young fish in southern waters to survive in numbers to adulthood, despite those favorable conditions for liatching the eggs which these waters may afford? And it is equally logical that in the far north the chances of survival after once hatching are much better. A great percentage may grow to maturity and increase very greatly the numbers of adult fish, and with them tlie average of the size. Naturalists have often commented on the fact that the species in colder waters although fewer in number each consist of vastly more individuals, than in warmer waters. Perhaps the difference in rate of mortality explains this — certainly it appears to harmonize with conditions in the sardine. But if the colder northern waters witli fewer enemies allow fish to survive after hatching, are the natural conditions as friendly to the floating egg? One might venture to surmise not, judging from what facts are known. For it has been in northern waters that the vast variation in the success of spawning seasons has been noticed. A favor- able year may allow myriads of eggs to hatch, while five, ten or more years may elapse without a recurrence of such favorable conditions. So the phenomenon of a dominating year class arises, concerning which we wrote in the last article in California Fish and Game cited above. This phenomenon has been noticed only in northern waters in such species as the herring and the cod. It seems to occur in our northern sardine, as witness the appearance of the great schools in British Columbia during the last few years. So perhaps we may find that the abundance of large sardines in our northern waters depends, first on the only occasional success of a spaAvning season, and then on the growth of a large part of the resulting young to maturity. Such an hypothesis seems to fit the facts, and explain the sudden great extension to the north of a commercial abundance of sardines. If, however, we go far enough to the south, say to Monterey, we niay find a region where there is both a reasonable chance of spawning successfully, and a comparatively low rate of mortality still. Then — like nations under similar conditions — the average age of the population would be high, and the young somcAvhat scarce among the many adults. But even there Ave might find in a modified degree the phenomenon of dominating age classes, making the sardine appear to be smaller or larger in average size at times. So some such conditions may yet be found at Monterey. Thus this second tlieoi-y must bo l)orne in mind, tliat conditions of existence may lead to varying kinds of populations. To the south, as at San Diego, the numerous young fish may find it hard to survive to maturity, to the extreme north the eggs may not develop save under favorable conditions recurring but seldom, and midAvay the adults may he more abundant because the young are able to survive the less numer- CALIFORNLV FISH AND GAME. 109 ous enemies. The hypothesis certainly harmonizes with the facts as we imperfectly know them. Yet other theories may fit these facts nearly as well. . For if surrounding conditions can modify the actual numbers of fish of various sizes, it is equally probable that they can modify their appearance in the commercial catch. There is no greater fallacy extant, it seems to us, than the assumption that the fishermen catch a fair, or even a passably fair, representation of what actually exists in the ocean. It remains to be proved in every case that a fisherman with his gear, or — what is far more dubious — a scientist with his apparatus, can take ^ a fair sample of any species or of any group of species. So for the third theory we may have one that is perhaps somewhat comforting to the commercially interested man: namely, that the difference in sizes is really an illusion. It is common knowledge that in the method of fishing many things vary from day to day. To some fisheries more or less smooth water is necessary for successful operations. Or market conditions may change and shift the demand from one class of fish to another. Or on one part of the coast fish are taken by one method and on another a different one is used, perhaps merely because of the nationality of the fishermen. So, great caution is necessary that careful investigation of the fisherman and his methods is made at the same time that the fish is studied. These things are comparatively easily discounted, but there is another category of circumstances not as readily investigated, namely, the effect of physical conditions, such as temperature or currents, upon the accessibility of the fish. There may be, for instance, many adult sar- dines at San Diego, but oceanic conditions may be svich that they are simply never seen, never appear to the fishermen. And the great run of large fish in the far north may not be due to the unusual abundance of some year's spawning, but simply to the prevalence of unusual con- ditions which may serve to bring the fish in. Or an adult fish may react dift'erently to temperature conditions, as is true of the albacore in a certain degree, and the change in temperature, however slight, may have a decisive effect in preventing the appearance of the large fish or of any particular class, save under the most favorable conditions. Or perhaps the varying salinity of the superficial layers of water may have a decisive influence, as is supposed to be the case in some parts of the North Sea. So there are many things which might be surmised to have an effect on the abundance of fish, so many and in truth so obvious, that fishermen are very prone to adopt this theory. Yet it is very easy to underestimate the ability of the fisherman to take the fish, and very easy to overestimate the sensitiveness of the fish to such changes as occur. Careful observation should be able to decide as to the probability of such occurrences as are mentioned in this para- graph, and to test the real presence or absence of the fish. To the average casual reader these theories must be confusing, and decision between them very difficult. But there is, indeed, every logical reason to believe that the phenomena which must result from any of these possibilities would vary in a manner clearly distinguish- ing them according to their origin. Thus the appearance of the large fish far to the north may be due to the dominance of one year class 110 CALIFORNIA FISH AND GAME. resulting from one spawning, or it may be due to favorable conditions bringing in tlio scliools toward sliore. But notliing slioidd be easier to the scientist with a knowK'dge of metliods of i-eadiug age from the scales than to decide whether the fish that come in are really made up. of one great year class.

It has recently been the writer's fate to meet several times the argu- ment advanced in all seriousness- that the killing off of the whales and the albacore leave a surplus of sardines which might as well be used as fertilizer. This argunu'ut for tlie presence of a surplus is untenable, as is well known by fisheries scientists. ■Many arguments more valid may be cited leading to an o])|)osite conclusion. In the first j)lace such animals as the whale, the albacore or tuna perhaps consume more enemies of the sardine than they do of the sardine itself. These fish, such as the anchovies, the mackerels, red cod, etc., probably feed on the young, as well as on the adult sardine. The anchovy, for instance, has a beautiful straining apparatus in its gills with which it might remove the eggs and larva^ from the water to swallow them. And the sardine eggs Mid young float freel.y in the open sea for such fish to take. These small things are so delicate that they must be destroyed immediately and no method of ascertaining the amount consumed is at hand. It is, on the other hand, easy to satisfy one's self about the sardines such (ish as mackerel consume. So the existence of the wliale and albacore mav be actually a benefit to the sardine fishery, and their destruction a disaster to the industry. A classic case could be found in Alaska, where the numbers of her- ring should supposedly be increased by the practical extinction of the halilnit, which consumes the hei-ring in (juantities. P>ut careful inves- tigation of the lialibut food showed conclusively that it ate more enemies of the herring than it did of the herring. It ate gray cod, CALIFORNIA FISH AND GAME. Ill long-jaw flounders, dog-fish, rat fish, red cod and black cod, each as often as it did herring — and every one of those species is a bitter enemy of the herring. Similar cases of mistaken conclusions as to the harmfulness of birds may be found. For many birds eat injurious insects to an extent that far overbalances any harm the birds themselves do to crops. The same is perhaps true of the whale and the albacore. In so far as the albacore is concerned, an endeavor on the part of the writer to investigate its food met with disaster. Por it was soon found that the fishermen were using sardines, anchovies and other fish for bait, or to chum the fish, and that the albacore which were caught had naturally a great many sueh bait fish in their stomachs. The same applies to the salmon. But, indeed, even ignoring this fact, it was found that such things as squids, small Crustacea, and fish of other species formed a large part, at times all of the food of the alba- core, tunas and salmons. Another argument just as valid as that in support of the theory of the surplus of sardines is available. For it is common knowledge that the whale eats even more anchovies than it does sardines, and the anchovies may make serious inroads on the food supply of the sardine, being nearly the same type of feeder. Therefore the destruc- tion of the anchovies must be advantageous, and the whale a benefactor, indeed. The point to what has been said, we would emphasize, is the positive fact that nature is exceedingly complex, and that those who come to ready and easy conclusions are inevitably wrong. We do not wish to assert in an unqualified way that we are correct in saying that the destruction of any such animals as the whale, the albacore, the tuna and such animals is a disaster to the sardine, but we do wish to assert that the balance is just as likely to go that way as the other, and prob- ably does. And that would be the case were all the suppositions advanced above untrue. And as a matter of fact, if such great numbers of albacore, of of tuna and of whales have been taken, it may be high time to propose some protection for them. The argument that there is now a surplus of sardines is a strange one to meet at this time. If we had three vessels at sea in a storm and two of them were sunk, would we talk confidently about the safety of the other? Yet that is just what is happening. The great salmon fisheries of the Alaskan and British Columbian coasts are on the verge of extinction, as everyone now knows, despite the fact that years ago statements that the supply was inexhaustible were quoted just as freely as they are now about the sardine. And the same is true of the halibut fisheries to a still greater extent. As in those two fisheries, once the two greatest on our coast, disaster has come, so may we well watch vigilantly lest disaster come' to another great fishery, that for the sardine. Abstract speculation on intricate things such as the effect of killing off the enemies of the sardine is worse than useless in the face of real experience. 112 CALIFORNIA FISH AND GAME.

CALIFORNIA FISH AND GAME. 113 FISHCULTURAL METHODS UPHELD. A recent newspaper attack on the methods and accomplishments of the fish- cultural department has brought forth many protests. Resolutions and letters in large quantity have been received from si>ortsmen's clubs, chambers of com- merce, forest supervisors, boards of super- visors, and private individuals pointing- out the successes attained in planting- trout. Among the sportsmen's clubs defending the present methods are the Sierra Rod and Gun Club, the Grass Valley Sportsmen's Club, Lindsay Fish and Game Protective Association, El Dorado County Rod and Gun Club, Caspar Rod and Gun Club, Fresno Sportsmen's Club, Yuba County Fish and Game Asso- ciation, and the Alturas Sportsmen's Club. All unite in pointing out that in order to keep up the supply of trout where there is heavy fishing, it is essential to stock the streams annually. Many point out that had not annual plants been made the streams would now be barren of fish life. Fortunately, the opposite condition exists, owing to fishcultural operations. Mr. C. J. Walters, of Independence, states that streams that are extensively fished have increased wonderfully since the planting of fry began. According to Robert E. Eddy, Secretary of the Lindsay Fish and Game Protective Association, it is the unanimous testimony of our mem- bers who know the streams and of ranchers in the mountains, "that fish are now being taken from places formerly bai'reu, since planting be^n regularly in this section." George A. Green, President of the El Dorado Rod and Gun Club, writes : "Prior to 1910 no eastern brook trout had ever been taken from the American River, the fish life being entirely limited to the rainbow trout. In 1910, our club received from the Fish and Game Commission some eastern brook trout fry. These were planted in the American River near Kyburz. We have received and planted some eastern brook fry every season since. Today fifty per cent of the trout taken from the American River between Riverton and Phillips Station are eastern brook trout. The same holds good in regard to all other streams in our counti-j'." All of the communications report satis- factory results and state that the fry are received in uniformly good condition. The one complaint evidenced is that individuals and organizations are unable to secure as many fish as they desire for planting puri loses. IN MEMORIAM — FRANK SHOOK. It is to be regretted that deputy Frank Shook, one of the oldest and most loyal deputies in the employ of the Commission, died on January IG, 1921, at his home in Salinas. From the time of his api>ointment as deputy, on November 15, 1907, Frank Shook was one of the most sincere workers of this Commission. He was always on duty and always gave the best service possible. He not only knew the violator and his ways, but he knew thoroughly Monterey County, the country which lie patrolled, and it is because of the fact that he possessed all of the many qualities that are so necessary in one entrusted with the enforcement of the law that he was so valued and trusted as an employee of the Commission. That his loyal service was appreciated by the Fish and Game Com- mission goes without saying. — J. S. H. THE NATIONAL GAME CONFERENCE. The annual National Game Conference under the auspices of the American Game Protective Association was held in New- York City on January 24 and 25. For the first time, the California Fish and Game Commission was represented at this conference. Dr. H. C. Bryant was able to attend, owing to a lectui'e program regarding nature guide work which was made possible by Mr. Stephen T. Mather, Director of the National Parks. Dr. Bryant gave an illustrated lecture on the subject, "Education as part of the con- servation program," in which the work of the California Fish and Game Commission was outlined ; emphasis being placed on the work in the schools and in the summer resorts. At the banquet, the last night of the conference, motion pictures showing wildfowl on Lake Merritt, California's first game refuge, were shown and received very favorable comment. Outstanding features of the program were the discussions on a federal license, 114 CALIFORNIA FISH AND GAME. to take the form of a stamp which can be ])asted on the state license, and on tlie need for a treaty with ncl^hlioring: coun- tries rehitive to inii;ral()i\v fisli<'s to siiiiple- nient the one rehitive to liirds, which is already in existence. Consideral)le interest was also displayed in the reiMjrt of the \'irj;inia Fish and Game C'ommissioner regarding a law to control the vagrant dog. The law which is administered hy the Fish and (Jame Commission has been effective in the destruction of oD/MX) vagrant dogs since its enactment. That any state should have a dog problem, as well as a cat problem, was a suiiirise to those attending the conference. •A large number of resolutions relative to the conservation of game were passed. THE STEELHEAD, A DISTINCT SPECIES. The exact status of the steelhead trout has long been a mooted question. Although for many years considered specifically distinct, it has in more i-ecent years been considered a sea run form of the rainbow. The United States Bureau of Fisheries now announces (Bureau of Fisheries Document No. SW>, pp. 0-7) that Dr. W. C. Kendall, scientific assistant and ichthyologist, is bringing to completion a report which it is believed will settle the much discussed question of the specific identity or distinctness of the rninl)ow and steelhead fronts. "After a careful study (>f the fish from laxonomical, anatomical, and distribu- tional evidence the conclusion is reached that there are at least two wild fonns which have been confused under the names of rainbow and steelhead fronts. One is predominantly migratory (ascending fresh waters from the sea), the other pre- dominantly a permanent fresh water in- habitant. The name Salnio iridciis was originally bestowed upon a small steelhead form, as was also Sahno riviilaris. There is ab.solutely no doubt concerning the proper application of Sal mo gairdncrii to the steelhead, as Uicbardsdn's description is that of a large ar the name, not Sdhiio ir'ulciis. but Sahno shdsta. The fishcultural rainbow stock has been more or less affected by admix- ture of another form princiiially frt)ni Klamath River, which may be another form or species of rainlK)w or perhaps a steelhead. This admixture is clearly per- ceived in tiie appearance and structure of many specimens of the rainbow stock of some of the hatcheries. The steelhead stock has always, so far as known, been unadullei'ated Sohno fininbicrii, although in the distribution from hatcheries it is known that in some instances the two forms have been regarded as identical and distributed as rainbow trout. Pure Salino shasta is distinguished from pure Salmo f/airdnerii by the smaller scales of the former." SALMON DESTROYED ON SPAWNING BEDS. Because of the law which allows of the taking of three salmon by means of a spear, in districts one and two, between September 2."» and November l.">, many salmon are being destroyed on the siiawn- iug beds in Shasta and Siskiyou counties. Aliens, as in other cases, are the greatest violators. They often build a sort of traj) across a stream and working at night .spear the fish as they move through a narrow entrance to the trap. As many of the fish are unfit for food, because on the spawning grounds, these violators sometimes kill as many as from fifteen to twenty Hsh and save but the three that they are allowed by law. The deputies of the Commission have didiculty in apprehending these vio- lators because they work at night and because they are not to 1k> found with mon^ than the legal limit in their possession. Fortunately, sentiment in tlu'se counties is changing and many now see the danger in allowing salmon to be taken by means of a siM>ar during the spawning season. It is to l)e hoiied that there will Ix; sufficient s(»ntiment to make possible a change in the law during the present session of the legislature. CALIFORNIA FISH AND GAME. 115 BLUE JAY HUNT IN SAN BENITO COUNTY. Several years ago blue jay hunts were in vogue, but more recently little attention has been paid to the bird accused by the sportsmen of destroying quail's eggs. Of late, however, a well organized blue jay hunt was held at Hollister, California. Sixty sportsmen were divided into two rival teams and a week chosen for the hunt. When the final count of birds was made at the end of the week the total showed 1531 blue jays. One team out- distanced the other by 210 birds and this winning team were the guests at a big barbecvie held by the other team. One hunter bagged 233, and the second best was 1.30. energy in trying to determine the food of the blue jay as they do in making a largo kill of birds a solution of the problem will be forthcoming.

Kelly, a former assistant of the Bureau of Fisheries and now the executive officer of the Fish and Game Commission of the Territory of Hawaii, gives an interesting report on the rainbow trout resulting from eggs supplied by the Bureau of Fisheries in 1019. Before making an application for another shipment of eggs to be hatched and planted on government reserves, Mr. Kelly went to Kauai to determine how the trout planted in the streams of the island were thriving. He found the |)eople enthusiastic over the species and in the streams which had been stocked manj- trout were seen. Some of the fish were caught. The largest measured 7§ inches and others 5| inches. These were taken exactly six months after planting. Requests were made for plantings in the movintain streams of the islands of Molokai and Maui. Their beautiful coloration and rapid rate of growth are prime factors in the success of the importation experiment to the sportsman and tlic fishculturist alike of Hawaii. A DECLINE IN THE CONSUMPTION OF FISH. "How arc we to meet the decline in the consumi)tion of fish and the resultant hardship on the fishing industry of the United States?" — is the question of the United States Bureau of Fislieries. Dur- ing the period of the war the consumption of fishery products grew to considerable extent, which resulted in an expansion of facilities for the eai)turo. lu-eservatiou and marketing of these products. Des])ite the more adequate facilities for supply aiul the general advancing costs of materials and laboi*, there was a decline in the fishing industry. Not only on the eastern coast is this the case but it would appear to be true to a certain extent in the west as well, as is demonstrated by a graph published in the 1920 Biennial Report of the California Fish and Game Commission giving a com- parison of fish of all kinds packed in northern and southern California. A slight decline in the total number of cases of fish packed is shown by the following figures : 191S Southorn 1,38^,202 Northern 729,100 1019 l.UMnllJ.". 905,200 Total 2,114,302 21,071,641 1918 2,1 14.302 1919 2,071,f>41 42,001 However, in California, the salmon, and particularly the sardine catch, has steadily increased, as stated for the period 1917- 1019, yet the estimated 1920 pack of canned salmon in the United States, CALIFORNIA FISH AND GAME. 117 including Alaska, is about 3^ million cases less than iu 1917 and includes about 2i million cases of the cheaper grades (pink and chum), which it is reported are being offered for sale for less than the cost of production and can be sold with profit by the retailer at a low price. The canners of sardines and the cheaper grades of tuna are confronted with similar difficulties. Tiie problem is indeed one of import- ance, for aside from the fact that fish is our cheapest and best source of natural food supply the fishermen are, most of them, small, individual producers with little or no training for a change of liveli- hood and these men will suffer, if the industry is allowed thus to decline. accidents during the open season, as well as being a conservation measure. In 1917, twenty-eight fatal hunting acci- dents occurred in Michigan and Wiscon- sin. Out of this total, twenty-two oc- curred in Michigan as against only six in Wisconsin. The reason for the disparity was again laid to the fact that bucks only were allowed to be killed by deer hunt- ers iu Wisconsin, while in Michigan the big game hunters were allowed to kill witlujut waiting to see the horns. And so it continues to be demonstrated that the but k law in California and other states is largely responsible for the reduc- tion in the number of hunting accidents. Fig. 39.

Quoting from the Conservationist for December, 1920 : "The deer hunting sea- son of 1920 closed with only one fatality due to a man being shot in mistake for a deer. Last year there were nine deaths from this cause, during a sea.son when both bucks and does could be legally shot. Restoration of the buck law, and the requirement that a hunter look for horns before he shoots, is unquestionably to be thanked for the low mortality this year." The buck law is one of the prime fac- tors in reducing the number of hunting A CONSERVATION READER FOR CALIFORNIA PUBLIC SCHOOLS. "The wave of enthusiasm for the con- servation of our natural resources must reach the children or it will expend much of its force uselessly." With this end in view, H. W. Fair-banks of Berkeley, California, who is the author of many text books on geography, has written a Conservation Reader.* The book brings out in a simple and interesting manner the principles of conservation.

The book is illustrated with two colored plates fur- nished by the National Association of Audubon Societies and with various re- productions of photographs. "The movement for the preservation of natural resourc<>s can succeed only with the establishment of an enlightened pub- lic sentiment on the subject. To create and maintain such a sentiment is the proper work of the schools." The use of this conservation r.-ader in the schools should help greatly in developing the right attitude toward natural resources and the consequent attainment of proper conservation of them. PRESIDENT HARDING IN SYMPATHY WITH WILD LIFE CONSERVATION. Mr. T. (J. Pearson. I'r.'sjdcnt of tht National As.sociation of A u d u It o n Societies, in answer to a telegram, re- ceived the following telegram from Presi- dent Harding, who was at the time President-elect. "I am fully in favor of a policy which will guard the integrity of our national parks and our bird reservations. I favor the enforcement of our treaty with Can- ada for the protection of valuable migra- tory birds. Please accept my greetings to your Assoc-iation." (Signed) Warren G. Harding. Those who are interested in our na- tional parks and in the conservation of our wild life take great satisfaction in the expresseil altitiidc of President Harding. FUR-BEARERS PROTECTED IN TRINITY REFUGE. Game Refuge No. l-D has hem closed to trapping excejjt for coyotes, mountain lions and bobcats. This restriction will bring about the same object with refer- ence to fur-bearers as that attained for deer. The refuge is an ideal one for this purix)se and if the law can be enforced and the predatory animals exterminated, it is absolutely certain that these species will be preserved forever, and that to a large degree the overflow can be legiti- mately trapped. Similar provisions for preserving fur-bearers should be applied to other refuges. — E. V. Jotter, Weaver- ville, California. THE FUR SUPPLY AND ITS MAINTENANCE. Mi: Xed Dearborn. Assistant Biologist, P>ureau of Jiiological Survey, has re- cently written a pamjihlet entitled 'Maintenance of the Fur Supjily."* In ; introducing the subject of his paper he !sa.\s, "to direct attention to the great I comm'rc ial importance of fur; to emjjha- size the need of iniintaining the siijiidy. which lately has been declining at an alarming rate; and to jioint out ways by which this suii;ily may not only be main- tained as to ([uantity but imjiroved as to luality, is the i)urpr,se of this circular. "'IMie subject is discu.ssed from the \i('\\ point of the farmer, to whom fur- liearing animals, if rightly managed, will ■ e a source of interest and profit." "The commei'cial history of America begins with fui'. and from the early days down to the in'es(Mit this has been an im- nortant artic'le in our domestic and for- eign trade." Till' World War lias changed the cen- ter of tli(> world fur trade from Europe to the I'uited States, and the center of aianufacture in the United States is New York City or the near vicinity. The United States has learned the art of dressing and dyeing the skins, as is dem- onstrated by the drop of forty per cent in the ratio of dressed and raw skins im- ported into the country. In 11)14. dressed skins imported were worth $3,50(MXM», while raw skins imjiorted were worth i);7.r.(M;.(K»l». In l!)l!t, .$4.(WO,000 worth !)f dressed skins were imported, as against .i;(>0.(X):).(HlO worth of raw skins. "A conci'ete examjtle of the rise in fur I)rices is alVordcd by the actu.-il record of one man's fur-lined o\ercoat. This coat, limnl with mink, in l!)i;{ cost .$.100. .\flcT wearing the coat two years the owner sold the mink lining for .$1,000 and I'cplaced it with nutria at a cost of .$1."10. Two years lali r. in IIMT. he had the nutria lining remo\ed and sold it for $2.1(1. A niuskrat lining was then ))ut in the coat at a cost of .$.11. whicli, in 1910, was in turn removed and sold for $.3(¥). The original purchaser still has the shell." Although the price of furs is bound to drop to a certain extent, the fur dealers are not uneasy. The use of fur is being *U. S. Dept. Agric. Dept. Giro. 135, Nov., 1920. CALIFORNIA FISH AND GAME. 119 widely exploited — is being advertised for summer use as well as for winter — yet, there are two important factors to be reckoned with: (1) About one-half of the skins disposed of at American auction sales are of foreign origin. (2) The sup- ply of furs is waning to the extent that if the present condition sliould continue for a few years the .supply in settled dis- tricts would come to an end. The following remedies for the situa- tion are pointed out by Mr. Dearborn : (1) All trappers should be licensed at a nominal fee and at the end of the trap- ping season should turn in a complete re- port of the skins taken. This report to be published for the benefit of the public. (2) Farmers should be made to appre- ciate th? possibilities of this source of income. They should know that although most of the important small fur-bearers are carniverous, few of them are destroy- ers of poulti-y. "Among fur animals, as among men, the proportion of criminals is small." Skunk-proof poultry yards shotild be Installed, and the subsequent value of enticing the skunk to the fai'm- er's land to destroy the rodents advo- cated. Further emphasis should be placed on this natural source of income to the farmer, from animals which he neither has to feed nor shelter, so long as he rec- ognizes the value of preserving their dens and killing them with discretion. (3) The wisdom of killing fur-bearers only when the peltries are prime is force- fully brought out to the farmer by the associative argument, namely, that it is just as short-sighted for the farmer or trapper to kill fur-bearers before the peltries are prime as it is to harvest crops before they are ripe or when they are overripe. Hence, the value of limit- ing the trapping to a two months open season which is believed to be the most effective and efficient means of obtaining results. (4) The importance of having fur animal preserves and of domesticating the animals is of moment. Now that the characters of North American animals and their geographical distribution are well known, the production of superior fur should be much more possible. (T)) Animal dens should be protected, and the knowledge of the local attach- ment of animals used to good advantage. The use of poison, smoke, gas, or fumes in taking fur-l)earing animals should be prohibited. Mr. Dearborn's paper is of importance to Californians for he points out that in this state the as.set value of wild fur- bearers to the people of the state has been estimated at .$7,125,000. The an- nual catch of fur in the state brings about four per cent of this huge sum. "By proper conservation it might readily be doubled." Therefore, the value of en- couraging and promoting the fur indus- try along the right channels at this em- bryonic period in its development would seem most advantageous. CAMP SANITATION, Are you going camping this summer? The mountains of California constitute one of the most delightful of recreation areas, and an outing there may be most healthful and enjoyable if proper use is made of the opportunities offered. Proper use means, in a very important degree, good sanitation. If you take an outing you w'ill find that your pleasure is marred when you discover evidences of careless habits of other campers. Remember that you are one of many thousands of camp- ers that go to the mountains during a season, and that all have a right to expect you to avoid defiling the pleasure ground that is theirs as well as yours. Remem- ber ,too, that these mountains are tlie catchment areas for drinking water sup- plies of many thousands of people and that the purity of these supplies depends very largely upon the efforts of youreelf and other campers to practice intelligent sanitation. The principles of good mountain sani- tation are simple and their practice is not more burdensome than maintaining cus- tomary cleanliness around home. At home the person of common decency does not tolerate an accumulation in his yard of cans, bottles, papers, garbage and fecal matter, yet why is it that one may fre- quently see an otherwise attractive spot in the mountains littered with these things? Is it because the camp ground 120 CALIFORNIA FISH AND GAME. is only a temporarj' stopping place and campers lack the neighborliness to clean lip tiieir own refuse out of kindness for those who follow? Is it that same re- turn-to-nature, otherwise carelessness, that on a camping expedition contents a man to go a week or two without a shave? It is thoughtlessness, and care- lessness, perhaps laziness, but no part of nature. The principles of good mountain sani- tation are siuii)lc'. IJurn or bury all ref- use and use care not to contaminate streauLs. There you have a complete pro- gram for keeping our recreation areas clean. Take a small shovel and some matches with you on your camping trip and use them with iinulcnce. They will l;e useful for otlier than sanitary pur- poses. When you l)uilil jour camp fire burn your waste paper and when the meal is finished burn your garbage. Bury these iiiaterhils if you do not have a camp fire ; don't leave th'in for the next fellow to dis]>iise of. I'.ury also your unburnable ri'fusi', such as cans and bottles, 19 all owners of hunt- ing li(ens:'s in the State of New York were required to report the game killed for the preceding year. The statistics eomjiiled show that there were reported 4r.r)..lltu cottontail rabbits; ducks taking a fifth place in the kill showing a total of lOO.OC)^; male deer totaled 8,29.3. The grand total of game taken in 1918 was 1.. ^26,960. The game and fur-bearing animals of \ew York State, if capitalized, are worth not less than $.j3,000,0a) ; they return an annual dividend of more than .$.'>, 2(X),- (MK); and they cost the state for their protection and increase the nominal sum of .$1.S2,(KK>. This cost of itrotection and increast^ is thus less than six iier X'ont of the annual dividend. CALIFORNIA PlSH AND GAME. 121 FACTS OF CURRENT INTEREST. In 1920, Trinity County spent $1,323 in controlling the coyote. A bounty of $3 each was paid on 441 coyotes on which the reward was claimed. Salmon have appeared early this season, 150 pounds having been taken by trawling near the Farallones on March 3, 1921. In 1919 and 1920 the first salmon were caught after the middle of March. Although some of the ayu eggs imported from Japan hatched, they were so weakened by fungus that none of them survived. Deputies Carpenter and Britton arrested two men at Arbuckle during March who had in their machine 184 ducks. They were pre- sumably on their way to San Francisco to dispose of this illegal game. Both men were taken before Justice Jones at Williams, who sentenced them to sixty and ninety days, respectively, in the county jail. A bill before the legislature provides for a limit of ten abalones per day. This would effectively prohibit the commercialization of this sea food. Large shipments of edible crabs have been arriving in San Francisco. On March 12, 1921, a shipment amounting to four truckloads was received. No less than three bills which would abolish the present Fish and Game Commission have been introduced in the legislature. Two of them would make fish and game work depend upon appropriations by the legislature. 122 CALIFORNIA FISH AND GAME. HATCHERY NOTES. w I. SiiKiii.KY. l-Milor. SEASON PROSPECTS. As outlined in the January nuniljer oC California Fish and Game, the past season was a Very successful one from the standpoint of the number of trout fry roared, the quality of the fish planted and the systematic manner in wliich they were distributed, when the difficulties encoun- tered in the prosecution of the work, due to the extreme drouulit, are taken into consideration. Plans are under way for slill further improvements in the fish distribution work during the coming season. Within the next two weeks all applicants, who received trout fry last season, will be sent application blanks and will be requested to file their applications prior to the thirtieth day of April. Judging from recent cor- respondence with many of last season's applicants, there is going lo be an un]»re- cedented demand for trout fi-y (his coming season. This is due to several I'easons. There were very few losses of fish last sea.son. The success of fish planting dur- ing the ]>ast few s«>asons due to our closer cooi)eration with the applicanls and to sending of special messengers, trained in fish jilanling work, to assist and instruct in the best methods of handling and plant- ing the fry is beginning to show more satisfactory results and the pulilic is coining more generally to realize that it is only by extensive restocking of their fish- ing streams and lakes each year, tluit they may prevent depletion due to excessive fishing. Public association of anglers, resort owners and individuals, who are interested in one way or another in fishing, are taking more interest in the work, as the efficiency of our methods is demonstrated to them. Then to, Boards of Supervisors, Chambers of Commerce and public officials, having the business interests of their communities at heart, are coming to realize that fish and game are among the best a.ssets to a community, and that it is only by keeping the streams stocked with trout fi'y from the state hatcheries that the depletion of the fish in the streams and lakes can be avoided. They therefore consider, from a business standpoint, that appropriations of ade(iuat(^ amounts from their funds to l)rovide for jjroiier distribution of the tish allotted to llieiii by I lie Commission is money well spent. During the past several years of drought, it has been extremely difficult for us to obtain a suHicient number of trout eggs to supply all of the fry recjuired to adequately stock the waters of the state, despite the rapid increase in the extent of our opera- tions. This season we hope to materially increase our output of trout fry. No effort has been spared to make the com- ing sea.son the most productive of I'osulls that we have ever had. The older egg- collecting stations have been enlarged and improved to handle a greater output and hatcheries have been equii)ped to take care of all of the eggs which it is possible to secure. The new Lake Talioe Hatchery, as previously mentioned, has been finished and is ready for occupancy. The Mount Tallac Hatchery will be opened as usual about the middle of March and in addition to the egg-collecting operations, which have been carried on in past years at liie mouth of Taylor Creek, a new egg- collecting station will be operated on the upper Truckee River. Arrangements are being made to estab- lish an experimental hatchery near P.lairs- den, in I'lumas County, to take care of the requirements of the Feather River district, as well as the North Yuba River district near Sierra City. If this station can bi? successfully established, it will eliminate to a very great extent, the necessity of transporting trout fry for stocking the streams in Plumas County from the Mount Shasta Hatchery. This long haul is very hard on the fish and is very cxixMisive. If rainbow trout can be successfully reared at the Feather River, near Blairsden, which is centrally located, they can lie dis- tributed to far better advantage and with much less expense than to ship them from so great a distance as Sisson. By the establishment of this hatchery that section of the Yuba River in the vicinity of Sierra City can be handled to l>ctter advantage, as the long haul from Sisson to Nevada City and thence by auto CALIFORNIA FISH AND GAME. 123 truck over the hoavy srades along the Yuba River will l)e eliminated. Operations at the Monnt Shasta Hatch- ery and the various egg-collecting stations along the Klamath River are in full swing. While it is too early in the season to state definitely the number of eggs, which we can expect from the Klamath River sta- tions, we have every reason to believe that the take will be very satisfactory. The first of the rainbow trout are "running" in Rogrs Creek. Camp Creek and Fall Creek and something over a million of eggs have been taken to date. The ran of fish in Cottonwood Creek is somewiiat later, but indications are for a successful take of eggs at the Hornbrook Station. The f.almon frv which are being hatched at Mount Shasta and Fall Creek hatcheries are doing nicely and will furnish a fine lot of fry for distribution this spring and for placing in the large salmon rearing lakes where they are held throughout the sum- mer months and then liberated in the upper reaches of the Sacramento and Klamath rivers next fall. Steelhead egg-collecting operations are under way at the Scott Creek and Snow Mountain collecting stations and indica- tions are that a successful take of eggs at both places will l,e secured. Ukiah Hatchery is in readiness fOr the reception of the steelhead eggs from the Snow Mountain Station. Brookdale Hatchery is also open and prepared for operations.

Over threo-quarlers of a million of steelhead e^ss have been taken at the Scott Creek Station to date and are being cared for at Brookdale. A half million salmon fry are being reared at the Fort Seward Hatchery for distribu- tion this spring in Eel River, Mad River and tributaines of Plumboldt Bay. The hatchery is all ready for the reception of steelhead tront eggs from Ukiah Hatchery. Domingo Springs, Almanor and Clear Creek" hatcheries will be open for opera- tions during the middle and latter part of March. A crew of fishcultiirists will be s?ut into the Big Bear Lake district within the ne.xt two weeks and operations will be com- menced as soon as the lish start "running" at the North Creek Station. The Kaweah Hatchery will open for oi;erations shortly after the first of April. Wawona Hatchery will, as usual, lie opened sometime during April. The San Joaquin River Experimental Station is still in operation. The wcatluT has been extremely cold, the water being close to the freezing point for days at a time and development of the salmon eggs has been very greatly retarded. Three hundred thousand Loch Leven trout eggs were .shipped during the latter pari; of December to the Mount Whitney Hatchery and the resulting fry are doing nicely. Everything at this station is in readiness for the commencement of the season's operations. The seasonal W(irk on the grounds has been progressing nicely and the gardens promise to be in even better shape than they were last season. COMMERCIAL FISHERY NOTES. .\. r.. Si (>i-j[JJ 0, Editor. SHALL WE USE FOOD FISH FOR FERTILIZER? ^^'itll a poor market for canned fishery ])ro(lucts aixl a strong market for fertilizer and iioiiltry foods, a diHicuIt problem con- fronts the Fish and <;anii> Commission and the state legislature.

The catch "or irt2<) shows considei'alile d(>crease in the tota's in comparison with the catch for 11)10 whirli was 202,258,511 pounds. The sardine catch showed the greatest decrease, which was approximately P>Ty.- 000,000 pounds less than during 1!)]'.». Salmon, yellowtail, sole, squid and clams also declined, while the catch of albacore sliowed an increa.«e of about 5,000,000 Iiounds. The decreased (atch of sardines was on account of the poor demand for the canned and sailed i)roducts and canneries did not oi)erate their plants to full capacity during the year and many of those plants operating closed down early in the fall. During the spring of 101.0 there were great quantities of sardines used in rediiction plant.s for fish meal. In the summer of 1010, a law went into effcL-t preventing the use of edible fish in reduction plants and during 1020 there was no straight fishing for sardines for reduction purposes. CALIFORNIA FISH AND GAME. 125 The salmon catch hi tlie state shows a decreass of approximately trvvo million pounds, the total catch for the year being 11,138,693 pounds. Along the coast north of San Francisco the catch was about the same as the previous year, some particular localities showing slight increase, while other districts show a small decrease. The decrease in the catch was on Monterey Bay and the Sac- ramento River. The Monterey Bay catch was 1,309,000 pounds less than in 1919, which was by no means a good year for that district. The Sacramento River catch declined about 700,000 pounds. The water was very low in the Sacra- mento River during August and Septem- ber and no doubt this fact, together with the poor quality of salmon and low price, had considerable effect on the catch as a number of the fishermen laid up their boats and stopped fishing some time be- fore the season closed on September 24. During 1920 there were 1,941,984 cases of fish canned. Of this amount, 1,062,996 cases were sardines and 835,(345 cases were tuna, these two varieties of fish be- ing the principal fish used for canning purposes in this state. The tuna pack for 1920 was greater than during the previous year, while the sardine pack was lighter. The total ]ia:c'k of all varieties canned in 1920 was about 130.000 cases less than during 1919. Complete statistics of ' the fisheries for the year 1920 will be published at a later date and should show some very interest- ing data. — S. JI. D. SACRAMENTO RIVER SALMON MARKING, 1920. t^lien salmon hatching on a large scale began on this coast it was the custom to liberate the fry in the streams as soon as the yolk sacks had been absorbed. Of late j-pars the fry have been held for longer periods of time at the hatcheries on the belief that larger fi.sh are better able to take care of themselves when lib- erated in the streams. The small fry in the hatchery troughs are of necessity crowded and are accustomed to being fed at regular intervals. It is thpught that planting these small fry in a stream is too Siudden ,a change and that too many fall a prey to enemies before they learn to ' avoid dHiigers and forage for them- .selves. To overcome this difliculty the small fry are' transferred from the crowded hatchery trough to a large pond or lake where they have more room and are often able to find some natural food. From the pond the fry may be trans- ferred to the stream when they are con- sidered to be of sufficient size or when the height of water in the stream is con- sidered most favorable. Proof of the relative success of differ- ent times of liberating has been lacking, partially due to the difficulty of securing data. One method of .securing this proof is to mark some of the young fish from two or more lots of fry liberated at dif- fer?nt times. A comparison of the num- ber from earh lot recovered when they return to sirnvvn would throw some light on the success of the different methods of libTating. The great difficulty in all sucli marl ing experiments is that so few marked f.sh are recovered. In the clean- ing slieds large numbers of fish must be prepared for market in a short time and the fish are handled so rapidly that the missing fins of marked fish are either not noticed or are neglected, so that time is not taken to measure the fish, to take a sample of the scales and send the data to the office of the Fish and Game Com- mission. It is impractical to have a rep- res?ntative of the Commission at all of the fish sheds while fish are being re- ceived. Another difficulty is the possible ob- jection to marking fsh l)y th? r;^moval of fins or with metal tags in that one is never sure that the behavior of such marked fish is typical of the behavior of unmarked fish of the same brood. Never- theless some valuable data may be secured from such marking experiments. Xo other method has yet been devised for securing knowledge of the migrations of salmon in the ocean. In this connection, the first article in the- January, 1921, number of this magazine is of special in- terest in showing that marked fish lib- erated in the Sacramento River were re- covered not only in the Sacramento gill nets but also by trolling at such widely separated points as Monterey and Shelter Cove. At a conference (September 8. 1920) between representatives of the California Fish and Game Commission it was de- 126 CALIFORNIA FISH AND GAME. cided to try another Kinj? salmon mark- ing exporimont using Sacramento River eggs and liherating in the Sacramento. The ohject of the exi)eriment was three- fold, first, to contrihuie ro tlie knowl- edge of ocean migrations and, second, to throw some light on scale readings by comparing the hatchery lake growth with the normal stream growth. The third and clii 'f olg 'ct was the comparison of three m ■thuds of liberating fry: Ulcerat- ing (1) Inriii' fry in the fall. {'2) year- lings in till' spring, and (3) .small fry in the sjiring. 'I'o accomplish this it was planned to mark three hatches of fish corresjjonding to the three enumerated above. Of tin- first two hatches of fry from Xovend.er. I'.H'.I. eggs, the first was to he marked ;ind lil;erated in Septem- ber. 1J)20. and th > second in the si)ring of 1!»1:1. The third, from the fall of 1923 eggs, to be marked and liberated in the rpring of llllil. Th? first batcli was marked as i)laune(l but the remainder of tlie ex])eriment was unexpectedly ui;set by the behavior of the Sacramento Kiver. These marked fi.sh were to have been liberated sometime in November of 1920. but the fall floods of the Sacramento broke levees and it was feared that too great a loss of young fry would result if the liberation were made during the time of floods, so it was necessary to hold tiie fish over winter. However, the marking already completed should contribute something toward de- termining ocean migrations and possibly scale growth characteristics. The follow- ing is an account of the marking of the fir.st batch of salmon fry. Source of Eggs and Hatching. The King Of ('hinook salmon rggs were taken ] y ihi' I'nited Stat;s Bureau of Fishei'ies at its substation on Mill Cre:>k, a tributary of the Sacramento River. Tehanui County. California. The eggs were taken the latter part of No- vember. 1919, eyed at Mill Creek and sent in a shipment of 1,2.">S,000 to Sisson. California, where they were received February 10, 1920. They were hatched the latter part of February at the Mount Shasta Katchery, a state hatchery at Sisson. After several weeks in the troughs the fry were transferred on May 27, 1920, to Klink's Lake, one of the three lakes at the hatchery used for hold- ing fry before the final planting in the str am. Here they remained till the end of Seijtendjer when part of them were re- turned to the hatchery for the purjiose of marking. Size of Fry. Tli'S' fry in the latter part of Septem- ber, 1920, were ten months old reckoning from th(> lime the eggs were collected or seven months from the time of liatchlng and had siient four months in Klink's I^ake. A sami)le of 12n of these fisii taken at r.mdom on September 27 showed an average length of 7.9 centimeters, or 3.1 inches. The greatest extremes in length of f.sh from this sample were 5.8 to lO.S centimeters, or 2.3 to 4.2.'i inches. Other extreme cases wei'e found wliere th.e range was from 4.5 to 13.0 centi- meters, cr l.S to 5.1 inches.

Certain sportsmen's angling clubs are advocating the use of barbless hooijs for catcliing fish, arguing that it is more sportsmanlike for it gives the fish a chance for its life. Besides its being a more creditable performance, they say, to catch fish with a barbless hook, the undersized fish when returned to the water will be more apt to survive as they are hurt very little. It is interesting to note here that the commercial fisheimen in fishing for long- finupd tuna, skipjack and bonito in south- ern California use principally barbless hooks. The motive in their case is not to give the fish a better chance for their life, but to enable them to catch them faster, for the barbless hook is more quickly extracted and time is thus saved when the fish are coming fast.

An animal, purely a vegetarian, that plays great havoc with gardens all through this country, is the porcupine. Sometimes, all of the garden stuff on out- lying ranches in this section is com- pletely destroyed by this pest. One of our rangers trapped a good many porcu- pines in his garden at a ranger station last summer, and he and his family used them to a considerable extent as food. I have eaten porcupine meat on several occasions during the past summer and found it to be quite palatable. Only for the fact that the meat is coarser in tex- ture, one could imagine he was eating beef — provided of course, that the porcu- pine is young. An old porcupine is the toughest chewing imaginable — Wm. S. Brown, Alturas, California. 128 CALIFORNIA FISH AND GAME. TREE SQUIRRELS INFESTED WITH SCABIES. A (lead California gray squirrel (Scinrus griseus griscus) was recently sent to the University of California by Deputy Eiioll Cray from Placerville, California, for post nioiteni, as it was afllieled with a disea.se which has been killing off great numbers of gray squirrels in the El Dorado National Forest. The disease was first noticed among the squirrels on the Georgetown Ridge in 1917. The gray squirrels were prac- tically exterminated in this district. Since then, the disease has spread from this vicinity and is now most noticeable in the southeastern part of the county. The first evidence of the disease is to be seen in a scaly or mangy appearance ni-ound the head and neck. This is fol- lowed by sores over the rest of the body and the hair falls off. Dead squirrels are to be found at the bases of trees and in streams of water. P^xamination, by the veterinary and entcinological departments of the Univer- sity of California of the specimen sent in showed the disease to be a form of scabies. According to Professor Stanley B. Freeborn, the cause is to be found in a mite belonging to the genus Notocdrca. These mites live in little tunnels dug in lli(^ skin .'iiKJ tlicy eventually cause bad sores which weaken the animal to such an extent that death finally ensues. A closely related .species found on the cat has recently been transmitted to the rabbit, horse, dog and man, always with dilliculty and with no serious effect. Laboratory rabbits infested with a simi- lar species of mite invariably die a more or less lingering death, if left untreated. Thorough washing followed by api>lica- tions of sulphur ointment repeated three or four times, at intervals of five or six days, generally produces satisfactory cures in these animals, if taken early. It is to be hoped that this epidemic will disappear, as do most epidemics of this kind. — II. C.

By Harold C. Bryant. From being the most maligned of all birds, the hawks and owls are now coming to be recognized as among the most helpful to mankind, 3Iembers of this group have been continually persecuted because a few species have shown themselves to be destructive to domesticated birds and mammals. Each hawk and owl has been judged by circum- stantial evidence, and prejudice has caused the good to suffer with the bad. In recent years, the farmer has come to a realization of the great damage caused by ground squirrels, gophers and other rodents and he 12053 134 CALIFORNIA FISH AND GAME is willing that all the natural enemies of these pests should be en- couraged. As a consequence, state laws protect the beneficial species of hawks and blacklist the destructive ones. Nevertheless, a beneficial hawk hanging on a roadside fence or tacked to the side of a barn is still a too prevalent sight. With the exact data on food habits that we now possess, there is no excuse for ignorance as to the economic value of each species. In the hope of stimulating interest in the preservation of the bene- ficial raptores the following analysis of the destructive and beneficial hawks has been made, together with a field key, which, it is hoped, will make identification possible. BIRDS OF PREY. Birds of prey are recognized by strongly hooked bills with a soft skin, the "cere," surrounding the nostrils, and by the large strong feet with flexible toe joints, and long, curved, sharp talons which are powerful weapons for grasping and killing prey. Of particular use are the latter in holding the prey while it is torn to pieces. In the vultures, which are carrion feeders, the talons are not so well developed. All have a swift, sure flight. Their whole structure betokens ' ' strength, activity, ferocity, and predatory nature." Although the above ana- tomical characteristics are held in common by all the raptores, yet a close study shows that the different species are grouped together be- cause of like habits rather than because of like structure. Hawks fly by day, and in the economy of nature owls take their place at night. The owls may be distinguished by their eyes being di- rected forward and by the disks of radiating feathers which surround the eyes. They are among the few birds which have binocular instead of monocular vision. Hawks have less fluffy plumage and smaller heads than owls. The hawks are slow breeders, most of them laying but two eggs each season and rearing but one brood each year. The young grow very slowly and remain in the nest for a considerable period of time before developing the powers of flight. Identification of hawks is oftentimes made difficult because the same species frequently has two color i)hases. Blackish or melanistic forms are of frequent occurence in several species of beneficial hawks. Since dark colored birds do not appear among the destructive bird eating hawks, it is safe to say that all black hawks are useful. Another means of discriminating between good and bad hawks is to be found in the seasonal occurrence ; the destructive hawks are almost invariably winter visitants, consequently, the chances are that hawks shot in the summer are beneficial ones. As a rule the sexes are colored alike. There is, however, a marked difference in size, the female being the larger. The fluffy juvenile plumage makes the young bird appear larger than the adult. The food is made up chiefly of rodents and insects, and the birds gorge themselves whenever opportunity offers. Although the flesh is often picked from the bones, small animals are usually sw^allowed whole. Indigestible parts are often regurgitated in the form of pel- J^'K»^mJioiist^m SHARP-SHINNED HAWK (Right Hand Figure, Immature Female : Left Hand Figure.

The hair, bones, and other elements in a pellet can be identified and a comprehensive idea of the food may be obtained by a study of such pellets. KINDS OF HAWKS. Hawks are usually divided into four main groups: The meadow hunters, known as harriers (represented by but one form, the marsh hawk) ; the woodland hawks, known as accipiters; the soaring hawks, the huteos and eagles; and the "long winged chasing" hawks, known as falcons. Sometimes the carrion feeders, known as vultures, are in- eluded. THE BLACKLIST. By far the larger number of hawks are beneficial. It is, therefore, better to know the villians than to attempt to know all of the beneficial species. Attention is accordingly called to the following hawks which may properly be blacklisted. State laws give these hawks no protection. AH of the destructive species belong to the third group, the accipiters. All are typical bird hawks with long tails, short rounded wings, com- paratively small heads, and with a rapid, darting flight. In the open their flight consists of alternate flappings and sailings. Seldom, if ever, do they give any cry. All habitually frequent wooded or brushy areas. These birds usually watch for their prey from some vantage point and dart in among the trees or brush to secure it. In the hand, they are readily identified by their short broad wings, and slender un- feathered legs and feet. Three of the destructive species are very much alike in coloration and habits, their main difference being in size. We can, therefore, speak of three editions of the "chicken hawk." The first is the small sized "chicken hawk" known as the "sharp-shinned hawk." (See plate 1.) The second is the medium sized bird and perhaps the best known of all those attacking poultry, the Cooper hawk, sometimes called the "bullet hawk, ' ' and rightly called a ' ' chicken hawk. ' ' An additional field char- acter, to that of size in distinguishing the sharp-shinned from the Cooper hawk, is to be found in the shape of the tail. The tail of the sharp-shinned hawk is square-ended, whereas, that of the Cooper hawk is rounded. The third is the larger species found only in the higher mountains and in the northern part of the state, the western goshawk. All three are sometimes dubbed "blue darters" because of their manner of hunting. Very often they capture their prey in mid-air. The adult goshawk can be recognized in the open by its bluish colored back and wings and barred breast, as constrasted with the striped or streaked breast of the Cooper and sharp-shinned hawk. The young of the gos- hawk, however, have streaked breasts and can easily be confused with the Cooper hawk. The food of these three hawks is made up almost entirely of birds, the larger species feeding to a considerable extent on such game birds as quail and grouse, in fact, to such an extent that the Cooper hawk is often known as the "quail hawk" and the goshawk as the "grouse hawk." The Cooper hawk often attacks pigeons and returns day after day to claim a victim. Stomach examination has shown that this hawk feeds almost wholly upon wild birds and poultry. Of all the common hawks this is the most "audacious highwayman." It preys commonly 2-12053 136 CALIFORNIA FISH AND GAME on valley quail. In a nest of a pair of Cooper hawks in the San Jacinto mountains the remains of three chickens, a blue jay and a chipmunk were found (Grinnell and Swarth, 1913). The sharp-shinned hawk, of much smaller size, feeds upon the smaller birds, almost all of the com- moner song birds falling prey to it. In the Fresno district, the birds wliich seem to suffer most from attacks by the sharp-shin are mocking- birds, intermediate sparrows, valley quail, and say phoebes (Tyler, 1913). This hawk dashes in and out among trees and shrubbery and often perches on larger limbs inside the foliage. It is most common about willow thickets and the trees along streams. A crashing sound as it strikes a bird in llie foliage often betrays its presence and little bundles of feathers ])ear mute evidence of tragedies enacted. All Fig. 42.

Courlt'sy of tlie rnil^d States Bureau of Biolog-ical Survey. three species are likely to make their appearance in the chicken yard, in fact, about ninety -five times out of a hundred it is one of these three hawks which is to blame when poultry is found to have been taken by a hawk. The duck hawk is the most powerful of the destructive species. It is a true falcon, and in Europe was considered the "noblest" of the birds used in falcony. It fearlessl}- attacks ducks and has even been known to attack some of the larger waterfowl. The rush of wings at it attacks its prey is said to resemble a heavy wind. Its food comprises birds, both game and nongame. Birds recorded as falling prey to the duck hawk in California are as follows : blackbirds, meadowlarks, red phala- ropes, black turnstones, murrelets, auklets, ducks, doves, ,iays, and even sparrows. Furthermore, it is said to kill apparently for pleasure. At CALIFORNIA PISH AND GAME 137 any rate, it often kills more birds than it eats. Stomachs of two duck hawks from southern California, each contained the remains of a mourn- ing dove. The short tail, pointed wings, slate-colored back, and black patches on the face should help in identifying this bird; but the gen- eral actions are still more useful in recognizing it. The prairie falcon, much like a duck hawk in appearance, lives in the rough foothill country, nesting about cliffs, and is noted as a destroyer of ground squirrels. Although a close relative to the duck hawk, it is to be numbered among the beneficial species. BENEFICIAL HAWKS. The two best known beneficial hawks are the red-tailed hawk (see fig. 42) and the sparrow hawk (see fig. 43). The former is the large Fig. 4o. Sparrow Hawk (Falco sparverius) . Bureau of Biological Survey. Courtesy of the United States hawk commonly misnamed "hen hawk," which is most often to be seen soaring around and around high in the air over open country, or perched conspicuously on top of a dead tree or telegraph pole. In the adult bird, the tail is reddish brown, Init in the young birds the tail is barred. The common hawk call, sounding like the syllables "pee-yare," which so often drives poultry to cover, is given by this bird, but it very seldom bothers birds of any kind. The red-tailed hawk is a typical rodent hawk, having large clums}^ feet suitable for capturing small animals on the ground. In flight also, the bird is too slow and clumsy to be suc- cessful in capturing birds. The occasional red-tail that attacks poultry 138 CALIFORNIA FISH AND GAME is usually a young bird, showing that the species prefers other types of food. The food of this hawk is made up very largely of ground squirrels and mice, to which is added a goodly supply of some of the larger in- sects, such as crickets and grasshoppers. The stomach of a red-tailed hawk taken in the Berkeley hills contained one meadow mouse and two pair.s of jaws of the common ''potato bug," or ''Jerusalem cricket." One red-tail taken in Los Angeles County contained a gopher; and three others were found to have been feeding on rabbits (Bryant, 1918). Over ninety per cent of the food of this hawk is made up of noxious mammals and insects. Remains of two ground squirrels were found in the nest of a pair of red-tails in San Diego County (Dixon, 1917). In nests of the red-tail remains of gophers, ground squirrels, meadow mice, a young cottontail rabbit, and two snakes — a striped racer and a gopher snake — were found (Dixon, 1906). The red-tail preys upon snakes and may often be seen carrying a snake in its talons. Stomach analyses made by the government show over eighty-five per cent of the food to be rodents. A near relative of the red-tailed hawk is the Swainson hawk with a white throat and dark band across the breast. This is the only Cali- fornia hawk which develops a flocking habit. During the migration period, Swainson hawks may be seen in flocks moving leisurely across country. This bird might well be called a gras-shopper hawk for it is most often to be seen capturing grasshoppers in open fields. The birds in catching grasshoppers are said to skip about in an awkward way look- ing as if rather a.shamed of the performance. This species also feeds on mice and gophers (Tyler, 1913). This is a fairly common hawk in our great valleys. Another relative less often seen is the ferruginous rough-leg, so called because of the feathering on the legs, which reaches to the toes. The bird, figuratively, wears boots, and this booted appearance is helpful as an identification mark, also the white underparts, often with a dark band, and the white patch at the base of the tail on each side. The rough -leg prefers open country and is often to be seen perched on the ground near squirrel burrows. This hawk, perhaps more than any other, merits the name "squirrel hawk." Meadow mice also prove tempting as food. A rough-leg taken at Cotati, Sonoma County, con- tained seven meadow mice (Bryant, 1913). The rarer red-bellied hawk is a bird of the lowlands and marshes, recognized by its reddish brown breast and its mode of flight, which re- minds one of that of a horned owl. This hawk feeds on caterpillars, insects and small rodents. The stomach of one bird taken near Corona, Riverside County, contained "potato bugs" (Stenopclmatus) and beetles, and that of another a pocket gopher (Pierce, 1919). The stom- ach of a third taken in Fresno County contained large hawk moth caterpillars, beetles and "potato bugs" {Stenopelmatus) , (Bryant, 1921). In the nest of a pair of red-bellied hawks in San Diego County, was found one ground squirrel and two pocket gophers, carried there to feed the three young birds in the nest (Dixon, 1917). In another nest was found a brush rabbit, hair of a ground squirrel and an alligator lizard (Sharp, 1906). Stomach examination has shown fence lizards (Dixon, 1906), Jerusalem crickets and caterpillars. CALIFORNIA FISH AND GAME 139 The golden eagle (see fig. 44), although often accused of stealing farm animals and poultry, is deserving of careful protection, for its food is made up almost wholly of the larger rodents. A nest examined by J. B. Dixon in San Diego County, contained the remains of eleven ground squirrels, largely the surplus carried to the two young birds in the nest (Dixon, 1917). Rabbits and ground squirrels are the principal items of food. The notable decrease in numbers has been due to the desire Fig. 44. Golden Eagle (Aquila chrysaetos) . (Drawn by R Ridgway. ) Courtesy of the United States Bureau of Biological Survey. of many to kill something large, not to a desire for relief from depreda- tions. It is particularly important that the golden eagle be left un- molested by the rancher. The bald eagle (see fig. 45) depends so largely upon fish as a diet that it is almost invariablj^ found along the sea coast or about large inland lakes. An occasional fawn, lamb, or pig is taken, but this eagle is pri- marily a fisherman. On San Clemente Island and other islands of the 3—12053 140 CALIFORNIA FISH AND GAME Santa Barbara group, where this eagle nests, it is said to feed on sheep and lambs, as evidenced by bones near the nest (Howell, 1917). The sparrow hawk (see fig. 43) is the smallest and usually the most common of all and is often to be seen perched on fence posts or tele- graph poles. It has a cry that sounds something like the words ''killy- killy-kiUjj-killy/' which sometimes gives it the name of "killy" hawk. The reddish brown tail of the adult and the black bars on the face will Fig. 45. Bald Eagle (Ilaliaectus Icucoccphalus). (Drawn by R. Ridgway. ) Courtesy of the United States Bureau of Biological Survey. help in the recognition of the bird, as will also its habit of poising in the air with beating wings. The sparrow hawk develops speed and captures its prey by dashing directly after it. From the sharp-shinned hawk the sparrow hawk is distinguished l).y sharp, pointed Avings which are in contrast to the short, rounded wings of the former. In the hand all of the falcons may be recognized by the notch near the tip of the bill which is lacking in other hawks. Although called "sparrow" hawk, this hawk very seldom preys upon birds, pre- ferring large insects and mice. Grasshoppers and large beetles torm CALIFORNIA FISH AND GAME 141 the principal items of food. Tyler (1913) reports grasshoppers as the staple diet of some sparrow hawks in Fresno County. The l&ss common pigeon hawk is to be distinguished from the more common sparrow hawk by its darker coloration, by a blackish instead of a brown tail, and by the white throat patch. This hawk has a habit of perching humped up on conspicuous perches and when frightened flies swiftly and fairly close to the ground to another perch not far distant. The pigeon hawk does not confine itself so largely to insects as does the sparrow hawk and is guilty of preying upon small birds as well as rodents. In lowland country the marsh hawk (see plate 2) is a familiar bird with its long wings, long narrow tail and white rump patch. It is usually to be seen flying along with leisurely strokes of the wings, about three or four feet above the ground, quartering back and forth over the meadows and marshes searching for its prey, which is comprised almost entirely of meadow mice. On the sight of a mouse the bird suddenly plunges downward and makes off with the luckless animal. The marsh hawk will occasionally help himself to a bird, or even to poultry if available. The author once saw a marsh hawk make off with a killdeer. It will be found, however, that individuals, rather than the species as a whole, are responsible for depredations of this kind. With the possible exception of the skunk, there is no animal that exerts better control on meadow mice than the marsh hawk. Young marsh hawks are reddish brown all over, but the adult male has a M^hitish breast, gray back, and wings with black tips — suggestive of a gull. This is the only American hawk belonging to the harrier or meadow hunter group and the only hawk which nests on the ground. The white-tailed kite, another hawk which is gull-like in appearance and which frequents the marshes, is now very rare in California and needs careful protection to save it from complete extermination. Its food habits proclaim it a beneficial hawk. The stomach of a specimen from Santa Rosa contained a meadow mouse. The osprey, or fish hawk, is found along the sea coast and around the larger bodies of water in the interior. The white head and breast are conspicuous. This bird feeds exclusively on fish, especially such slow moving ones as carp and suckers. The United States Department of Agriculture has pointed out that ''the sooner farmers, ranchers, horticulturists, and nurserymen learn that the great majority of birds of prey are their friends, and deserve protection, the sooner will depredations of noxious rodents and insects diminish." By encouraging beneficial hawks time and effort is saved, for they automatically help control rodent and insect pests, being ever alert and ready to move to a center of infection. If given a chance, they will prove more effective than either traps or poison. Protection of hawks is the most economical pest control measure. It must be remembered that even the so-called destructive hawks have their place in Nature, for natural enemies of birds tend to maintain within proper bounds the numbers of the species on which they prey and preserve their fitness. Many believe that the relation between the predator and the animal preyed upon is such that direct increase follows destruction of the predatory species. These same individuals maintain that on an area set aside as a refuge, increase of bird and animal life 142 CALIFORNIA FISH AND GAME will not be noticeable unless "vermin" be destroyed. Since in the early days abundance of ^ame was coincident with abundance of natural enemies this contention does not seem reasonable. Rather should one understand that under natural conditions there is a certain balance struck between a species and its natural enemy and oftentimes the ac- tivities of one help to balance those of the other. Forbush (1916) who defends the above point of view gives the follow- ing example : "The marsh hawk {Circus hudsonius) feeds to some extent on marsh birds and their young, but a much larger part of its food consists of meadow mice and frogs. These mice certainly would be very destructive to young birds were they not held in check, and large frogs are known to swallow the young of wattn- birds. Marsh hawks and other enemies prevent many frogs from reaching a size wlien they would be dangerous to young birds. "If nature is undisturbed, therefore, all the birds are reared and maintained that the land will support, but when civilized man steps in and disturbs the natural ar- rangement and balance, then, and perhaps then only, the natural enemies of birds may become unduly destructive, and must be chocked." Rodents constitute our worst farm pests. Were it not for natural checks to their increase it would be impossible to grow crops. Field mice have from four to six litters of young a year with from two to thirteen comprising each litter. It has been estimated that one pair of meadow mice are capable of producing nearly a million young in five 3^ears. Of course, such an increase is never really possible because of natural cheeks, including natural enemies. To eliminate natural enemies or even reduce their number disturbs the balance and increases the numbers of the pest. Of course, artificial means of check, such as trapping and poisoning, have been devised, but their use entails time, energy, and expense. By encouraging natural checks on the increase of rodents more can be ac- complished with less expenditure of effort. Most hawks eat rodents, and herein lies the reason for their encouragement, A FIELD KEY. Lest the good hawks be destroyed with the bad it is necessary to dis- tinguish friend from foe. Ability to recognize the different species of hawks is, of course, the shortest road to conservation of the beneficial and destruction of the injurious. The average person finds it difficult to name a hawk seen in the open by reference to the average bird book because the distinguishing characters given are those suitable for use with a dead bird or specimen. As an aid to identification of live birds in the open the following key of field characters is appended, a key which it will be found emphasizes quite different characters from the more familiar ones found in bird books. This key has been prepared as an experiment to determine w^hether keys of this kind are possible, or useful. No doubt more accurate observation would be productive of N. B. The United States Department of Agriculture has issued several bulletins dealing- with the economic value of hawks, notably the authoritative work, "Hawks and Owls of the United States," by A. K. Fisher, which may often be consulted in libraries. The value of each species is judged by the results of many stomach ex- aminations. Another review of the value of hawks is to be found in the National Geographic Magazine, Vol. 38 (Dec, 1920), under the authorship of Louis Agassiz Fuertes. "R-BRi,'C^- MARSH HAWK Order— Raptores Family— Buteonid^ Genus— Circus Species— Hudsonius National Association of Audubon Societies CALIFORNIA FISH AND GAME 143 still better field characters and in the light of later knowledge a better key devised. The characters which, must be studied in order to use the key are : mode of flight, shape or general countour, color, color markings, and habitat. Even a better character in some cases is the call, but this has not been widely used in the key because of the difficulty of conveying an idea of the call by means of syllables. Then too, some hawks are notably silent and others are heard to call only in the breeding season. Field Key to California Hawks. A Soaring flight ; birds of open country, or large bodies of water.

Snyder, Stanford University. Two skillful anglers, Dr. Ross Harbaugh and Mr. R. L. Handy, who regularly visit Lake Tahoe, report the not altogether infrequent capture of the royal silver trout, a species lately named Salmo regalis. That no mistake might be entertained as to their ability to distinguish the species a fine specimen was sent for determination to Stanford University where it was first described. This is the fifth specimen that has come to the liands of a naturalist, and data ol)tainod from it is of great value in assisting to build up a description of the species. Unfortunately, it was eviscerated and nothing may be said of the sex, gillrakers, stomach caeca, etc. The fish, caught one mile off Bijou, weighed 6^ lbs. and measured about 25 inches. It was greenish blue above, bright silvery on the sides and whitish below. There were a few very indistinct round spots on the head and on the sides below the lateral line. The fins were immaculate. This was a larger example than those originally described* and the head and fins were somewhat shorter. The following measurements are recorded in Imndredths of the length to base of dorsal fin. Length head .20, depth body .215, depth caudal peduncle .095, length snout .062, maxillary .11, diameter eye .0^, interorbital width .08, depth head .14, snout to occiput .124, snout to dorsal .455, snout to ventral .54, height dorsal .11, height anal .11, length pectoral .13, length caudal .165. Number dorsal rays 11, anal 11, pectoral 14, scales lateral series 145, above lateral line 20. There is no reason for confusing this species with any of the intro- duced forms as the Mackinaw trout for example, but it may be mis- taken for silvery examples of the Tahoe trout Salmo Jiensliaioi, concern- ing which some remarks may not be out of place here. This is the com- monly distributed trout of the greater part of Nevada and of the western slopes of the Sierra Nevada mountains, and it reaches its largest size in the Truckee basin. This basin includes the Truckee River, Lake Tahoe and tributary streams which form its source, and Pyramid and Winnenuicca lakes into which the river flows, and where its M^aters are finally carried off by evaporation. This basin, none of the water of which reaches the ocean, offers far greater environmental variations than is usual among much larger systems, and the trout seemingly react in a medley of colors, and assume a variety of minor characters such as are not often observed among individuals of a single species. jMany anglers distinguish trout by color and body proportions, and those that fish in the Truckee basin usually recognize several native kinds. First and most commonly known is the Tahoe trout with light olive body and an array of large black spots well scattered over almost the entire surface. Examples in the nuptial dress seen in the spring and early summer have metallic reflections shining through the body color, a broad pinkish stripe on the sides, and a scarlet patch on the cheeks and above the axil of the peetoi'al fin. The under surface of the lower jaw has two parallel stripes of bright red, and there is a spot of •BuUetin Bureau Fisheries. Vol. XXXII, 1912. CALIFORNIA FISH AND GAME 149 red on the tongue beneath the tip. One or more bright coin-like spots of orange may be found anywhere on the head. Then there is the silver trout of Lake Tahoe, large in size, silvery in color, with many small narrow spots on the body and fins. It is usually caught in deep water. The royal silver trout not known to some anglers, blue or greenish blue above, silvery on the sides, with very small or not evident spots, might be mistaken for the above. The Truckee trout is the resident fish of the river. It is usually smaller and more brightly colored than the Tahoe trout. Another is the redfish remarkable for the great flame-red patch on the cheek. It is a migrant from Pyramid and Winnemucca lakes, entering the lower Truckee River to spawn. Also there is the tommy, a more modestly colored and smaller fish which enters the lower course of the Truckee to spawn. Finally, the emerald trout of Pyramid Lake which is pale green above, silvery on the sides and with indistinct spots or none. This fish does not enter the river to spawn. Observation of these fish has convinced the writer that but three species are involved. There are the royal silver trout of Lake Tahoe, ;S^. regalis and the emerald trout S. smaragdns of Pyramid Lake. These are alike in some respects, and both difi^er from all the others mentioned in having coarser scales, 124 to 145 series between the head and base of caudal fin. They also have fewer gillrakers and other distinctive char- acters. As each is confined to its particular lake there is no occasion to distinguish between them, as there is no opportunity to mistake one for the other. The others, the Truckee trout, redfish, tommy, silver and Tahoe trout, all belong to one species, 8. henshaivi. The latter has fine scales, counts of a large number indicating 153 to 163 as usual while a few have as many as 170. Of these local varieties the redfish and tommy are perhaps the most remarkable, appearing as they do in two great waves of a nuptial mi- gration which passes up the lower Truckee River with the rise of water due to winter rains. Formerly these trout were so abundant as to fairly fill the river at times. The redfish appear first, and as they progress from the lakes their brilliant hues become intensified in the bright desert sun until the whole body shines with iridescent yellow, Vermillion and red, the cheek glowing like a coal of fire. The redfish migration wanes rapidly in March, the scouts of the tommies appearing mingled with the last straggling redfish, the more belated of which are lost among the advancing hordes of tommies. The tommy, the name taken from the Piute word tama-agaih, spriug trout, is smaller, gen- erally darker in color, and more heavily spotted than the redfish. Sil- very tommies and redfish appear late in the season, possibly individuals fresh from the lake. It will be recalled that the water of Pyramid and Winnemucca lakes is rather alkaline, not fit to drink, yet it supports great numbers of fish. We have here migrations of trout from the lake to the river, like those of steelheads from the ocean. It has often occurred to the writer that observations on the trout of this rather restricted basin might form a sound preparation for a more extended attack on the difficult prob- lems offered by trout of much wider distribution. 150 CALIFORNIA FlSil AND GAME THE NEW CALIFORNIA STATE FISHERIES LABORATORY* By Will F. Thompson. On June the thirteenth, construction began upon the new California State Fisheries Laboratory at San Pedro, the most important of our fisheries centers. It is to cost in the neighborhood of twent^^-five thousand dollars, and will accommodate the present scientific staff of the Department of Commercial Fisheries. The conceptions which gave rise to its building are novel and worthy of remark at this time, for it is not generally known that this project is a distinct and noteworthy departure, a fact which Californians should know and appreciate. The building will be located near Fish Harbor, San Pedro, within two blocks of the canneries there — with easy access to the vast store Pig. 50. Elevation of new State Fisheries Laboratory being built at San Pedro. of fish which is brought into them. The site has been granted to the Commission for a long period by the city of lios Angeles, and its ac- (|uisition has been a very fortunate thing. It is at the intersection of Seaside avenue and Tuna street, hence upon the two most important traffic ways in East San Pedro. Seaside avenue will, in the course of a few years, be connected wi1h a boulevard to Los Angeles, through Wilm- ington and Long lieacli. Tuna street, which is but a very short one, terminates upon the water front of Fish Harbor in the center of the canneries. The new l)uil(ling for the San Pedro office of the Commis- sion will bo l)uilt upon tlie same ])l()t of ground, of the same type of architecture and will face upon Tuna street. The laboratory building will be nearly fireproof, of reinforced con- crete, with tile partitions and red tile roof. A perspective view of it •California State Fisheries Laboratory Contribution No. 29. CALIFORNIA PISH AND GAME 151 is given in figure 50, and the floor plans are shown in figure 51.* There are two stories. The lower contains two laboratories capable of accommodating several workers, with windows facing nearly north and hence with splendid light for scientific work. It has also a large work- room, floored with cement and with a door through which a truck may enter. There are also a dark room for photographic work and a store room for supplies. The upper floor contains a large room to accomodate the extensive and highly technical library necessary in the work of the laboratory, as well as the files of statistical records which will accu- mulate. In connection with this room is a laboratory and another smaller room, the latter also destined for statistical files. A bedroom is provided for the accommodation of the student workers who may be employed. The purpose of this building is to provide quarters for the present scientific work of the commission, the aims of which have been previously stated in California Fish and Game, but which are well deserving of brief recapitulation in tliis connection since they are in a measure dis- tinct from those of any other biological laboratory, especially of any in America. They are, in the fewest possible words, the observation of the condition of the fisheries with a view to their preservation and freest possible use. That is, true conservation. The real abundance of fish in the sea is not obvious to whoever may look. A fishery may languish because of changing natural conditions, despite untouched abundance of fish ; or, on the contrary, constantly improved apparatus may yield larger and larger returns in the face of real over-fishing. A fishery is, indeed, highly selective in its action and dependent on many things other than the real abundance of fish. So it happens that "observers" of the highest scientific standing casu- ally contradict each other as to the existence of depletion and the in- exhaustibility of the sea. Is it any wonder, then, that the alleged criminal "exploitation," brought before legislative tribunals, pleads — as does the murderer at the bar — that his life be not taken without proof? For opinion, backed by scant evidence, is not proof, and "ex- ploitation" does furnish food for the nation and is respectable, wealthy, and of good reputation generally. Opinions do have a great deal of force where, as in the case of conservation of birds and mammals, mere observation in the field is convincing to any fair-minded person, but in the case of marine fisheries this is not true. So, in place of opinion, the real conservationists — and among these are man,y of the commercially interested men — must endeavor to furnish what is tantamount to legal proof. Such men as have composed the Scottish Fishery Board — men who have patiently and carefully ex- amined into the condition of various fisheries — have proved the ex- istence of depletion in several of these fisheries, and have demonstrated the character of data necessary, and we have profited by their experience. These data are statistics, so detailed, so extensive, and so accurately gathered that changes in gear, changes in fishing ground, and many other things may be discounted. Such data must also be examined and tested by the biologist with his criteria of over-fishing.

It worked so well that this season it was re- peated, and now five planes are kept busy, making both day and night flights to frighten off the wild ducks." The American Game Protective Asso- ciation makes the following criticism : "We have been told that permits were granted to the rice growers of California to use aeroplanes to frighten the ducks from their growing crops. This appeared to us to be a very good idea, as efforts to frighten birds away from growing crops by gunfire has never accomplished the results desired, and is nearly always used by unscrupulous gunners as an ex- cuse to shoot out of season. However, if aeroplanes under permits of this kind are actually killing birds, such permits should be immediately revoked." Last fall a motion picture was shown over the country of one of these hunts, and at the same timc«, pictures appeared in the Sunday news supplements which showed that many birds were slaughtered by being hit with the propeller and other parts of the machine. The projection of the motion pictures was discontinued when it was learned that this picture was caus- ing many protests, and that investigations CALIFORNIA PISH AND GAME 159 were being made to ascertain where the pictures were taken. The supposition seems to be that it was photographed in California, and that the airplane was operated by an army lieutenant from Cressy Field. If this proves to be the case, certainly some immediate provision should be made to protect the migrating water- fowl and to prevent a glaring violation of the 'Migratory Bird Treaty Act. The state law prohibits the shooting of game birds or mammals from an airplane, but does not definitely provide against ruthless slaughter by propeller and guy wires. bia Financial Times," a journal of finance and commerce, has published in full the report of Dr. C. H. Gilbert, of Stanford University, who points a dark future of the salmon run in the Fraser River. He offers the ominous prediction that "big years" are wholly a thing of the past. T'he same article accompanied by an edi- torial appears in the "Canadian Fisher- man," (March, 1921). On the basis of the findings of this scientist also, the American Can Company is planning to furnish only one-third of the number of Fig. 52. Airplane routing ducks from the rice fields.

During the war there was a noticeable dependence upon the results of scientific research. It is becoming more and more evident that more dependence can be placed upon conclusions of men who have scientifically investigated a problem than upon the guesses of the untrained worker. We have seen no better example of this change in attitude than in the recent re- ports regarding the prospective take of salmon in British Columbia during the coming season. Even the "British Colum- cans usually supplied the canneries of this section. Thus it can be seen that the predictions of a scientist bear more weight than those of the average fisherman who would predict, on the basis of past cycles, an- other splendid season for the year 1921. In Dr. Gilbert's article, "The prospects of Fraser River sock-eye run in 1921," he states that two entirely independent lines of evidence had pointed to a greatly de- creased run of salmon in 1917. One of these was the blockade of the Yale Can- yon in 1913, which was just in time to 160 CALIFORNIA PISH AND GAME intercept the spM-, ning run of that year — due to be a "big year," for prior to 1017, a biff year occurrefl without fail in every fourth season. In 1917, a pack of 500,000 cases was produced, little more than one-fifth the pack of the big year of the previous cycle. It is known to all packers and fisher- men that the year jtefore the largo run was always made conspicuous by the occurrence of large numbers of greatly undersized in- dividuals— male fish — which evidently con- stituted a class apart from the main body of the run. and which in the small years of each cycle were rarely encountered. The packers put up these fish separately be- cause they contained less oil and were paler in color, as an inferior grade. They were thus in a position to compare their abundance in the years of their occurrence with that of four or eight years previously. From observations made, it came to be currently believed that whenever the num- ber of small fish was relatively large then the big year which followed would be correspondingly increased in comparison with other big years. Then it became further known that the "usual run of sock-eyes to the Fraser were maturing the fourth year 0 miles from the municipal- ities that maintain them. Only residents or taxpayers of the mu- nicipalities that operate the camps are eligible as guests, and, because of the low cost of the outing, each camper is required to render on an average one hours' daily service as outlined by the director in charg«, and must also furnish his own bedding. Guests are well housed, fed, and entertained. The following rates for a two-week outing, including trans- portation, were in effect last year : National forest. City. Name of camp. Mis. to emr. Cost. Angeles Los Angeles Do do Stanislaus.. Oakland... Eldorado .. Sacramento 5eeley Radford... Oakland ... Sayles Flat 75 150 90 m.75 14.25 18.00 25.00 These rates were all for adults, and the rate.s for children under 10 were from 50 to 60 per cent of the above. The lower rates at the Los Angeles camps are probably accounted for by the fact that these camps have been in op- eration for several years, while 1920 was the first season for Sacramento and Oak- land. The Los Angeles camps accom- modated over 35O0 of the 5000 guests at the municipal camps in the national for- ests of the state. The business men of Sacramento are so well pleased with their municipal camp that they are rais- ing a fund of $10,000 to be donated to the city to build permanent cabins at the camp for sleeping quarters, such as are already installed at the Los Angeles camp. — Vnitcd Staies Department Agri- cultwre Weekly News Letter. ESTABLISH QUARANTINE ON FOXES IMPORTED FOR BREEDING. To protect owners of fo.\ farms, the Secretary of Agriculture has ruled that all foxes offered for importation into the United States from any part of the world, except those imported for zoolog- ical gardens or similar institutions, shall be subject to inspection by an inspector of the Bureau of Animal Industry. The foxes must also be quarantined under the supervision of the inspector of the bu- reau until it can be determined by in- spection or examination whether they are affected with a contagious disease. If such disease is found, the animals must be re- trrned to the country of origin or be de- stroyed. This regulation goes into effect .lune I, 1921. The new regulation states that per- mits mu.st be procured for all foxes of- fered for importation into the United States as provided by Regulation 11, for the importation of cattle, sheep, goats and swine, and all foxes imported for breeding purposes must be entered through ports designated for the entry of foxes as follows : Boston, Massa- chusetts ; New York, N. Y. ; Rouses Point, N. Y. ; Calais, Maine ; Pembina, North Dakota ; and Seattle, Washington. They must be accompanied by an af- fidavit made by the owner or importer declaring clearly the purpose for which the foxes are imported, viz, whether for l)reeding purpo.ses or for zoological gar- dens or other institutions. Feed, at- tendants, and quarantine will be at the expense of the owner, and each owner or his agent shall give satisfactory as- surance to the inspector at the time of admission to quarantine that such pro- vision will be made. The place of quar- antine, it.s construction, arrangement, and equipment will be subject to the ap- proval of the Bureau of Animal Industry. The demand for fur and the attractive prices which it commands has interested many people who are favorably situated to breed fur-bearing animals. A num- ber of fox farms have been established in the northern states. To encourage this work and to guide those who under- take it. the department has published Farmer-s' Bulletin 795, the Domesticated Silver Fox ; and Yearbook Sei)arate Cti)?,, Fur Farming as a Side Line; and Depart- ment Circular 135, Maintenance of the Fur Supply. THE SILVER FOX RANCH AT LAKE TAHOE, CALIFORNIA. Mr. William Lewis, of Lake Tahoe, re- umed from a trip east last October with ix splendid specimens of registered silver black foxes to add to his ranch. These were all purchased from the Borestone Mountain Fox Ranch of Onawa, Maine, after careful inspection of the best CALIFORNIA FISH AND GAME 165 ranches in Canada and the United States. The present investment is still further proof of Mr. Lewis's confidence in this most interesting breeding industry. His ranch is at Pomin's, in a beautiful situa- tion on the shore of Lake Tahoe. It has been built according to the most modern methods and is today probably the most up to date ranch in the west, containing nothing but high-grade registered stock. Mr. Lewis believes in purchasing ani- mals only from such high type blood-lines as have actually proved their value in com- petition. It was for this reason that he purchased all his stock this year from the B'orestone Mountain Ranch, which the re- cent fox shows have proved is the leading ranch of North America. Mr. Lewis re- ports that this ranch is on the top of a mountain in an ideal situation in the heart of the Maine woods. But the fundamental reason the Borestone foxes are today the champion prize winners over all other foxes, Canadian or American, is due to their careful breeding. Their owner, Mr. R. T. Moore, a graduate of Harvard and the University of Pennsylvania, has made a study of the breeding methods, employed in the development of our famous race horses and registered live stock and has applied them to the improvement of foxes. That these methods have been success- ful has been proved at the big fox shows, held in the East, at Boston, Montreal and Muskegon, during the past two years. At the very first live fox show the Borestone foxes swept the prizes, winning as many ribbons and cups as were won by any three competitors. A pup, eight monthf^ old, Borestone Sirius, was awarded the grand championship over all the adults. Among his competitors was the brother of "Reid," a fox that subsequently won the championship of the Montreal Show in 1920, and is owned by Mr. Moore. At the much larger show held in Bos- ton last December, the Borestone foxes again triumphed, winning fourteen rib- bons and five of the eight silver cups of- fered for thoroughbreds. Of the three remaining cups, one was awarded to the Borestone ranch, but was refused by the owner, as he had offered it himself, and a Borestone fox tied at 93% points for the other two. In addition a fox born on the Borestone ranch, "Borestone Loami," was awarded the highest score in the show, 96 points, winning two silver cups and the nternational Championship of North America. In the field against her were one hundred and fifty foxes and forty of these were of the best Canadian strains, seven of which had already won prizes at the Montreal Show. One of these defeated oxes, subsequently, won the grand cham- pionship of the Muskegon Show, where the Borestone foxes were not entered. Mr. rioore now owns the grand champions of he three big fox shows and the only two fjxes, that have ever been awarded 96 1 oints or more : Borestone Loami 96 points. Interna- tional Champion, Boston, 1920. Borestone Reid, 96 points. Grand Cham- pion, Montreal, 1920. Borestone Sirius, 93 points. Grand Champion, Boston, 1919. Nearly every fox purchased by Mr. Lewis is closely related to these famous animals, or to the other eleven prize winners, of the Borestone ranch. His 'Tahoe Loami" is a daughter of the fa- mous "Borestone Loami," his "Tahoe Ot- to" is a half brother of the same fox, and 'Tahoe Lone Star" is a nephew of "Si- rius" and also of "Borestojie Rigel" 94^ points, champion pure black fox. With such stock the Tahoe ranch has a splen- did foundation, and under the ideal con- ditions at Tahoe will no doubt make a plendid showing. Fox breeding today is beyond the ex- erimental stage. It has been placed upon sure foundation by the progressive work f the American Fox Breeder's Associa- ion. Until this association was formed t was impossible for a novice to tell the clifference between poor foxes and good cues. Mary inferior animals were sold at fabulous prices by unscrupulous fox raders and promoters. This will no onger be possible, if the prospective fox Ireeder will take advantge of the oppor- unities, provided by the American Asso- ciation, for him to differentiate between good and bad stock. First of all, they have established a standard of perfection, by which a fox may be judged. Second, they created an advanced registration sys- tem, by which all superior foxes, that should attain 85 points or more under the standard of perfection, could be reg- stered as of undoubted first quality. Third, due to Mr. Moore's enthusiastic 166 CALIFORNIA FISH AND GAME promotion and energetic effort, despite the cold wator thrown on the movement by the older breeders, the first live silver black fox show was held in Boston. It was a com- plete success both financially and other- wise. The Canadian government sent the chiefs of their department of conservation to it, to consider the possibilities of hold- ing a similar show, and the Montreal show of 1920 was the result. As a consequence of tlrese innovations, the prospective purchaser can now be sure of getting really first quality foxes for his money. He should insist that the parents of his foxes are, not only pedigreed and registered animals, but that they are also in the advanced registered class. Better still, he should, if possible, attend one of the big fox shows and there see for him- self what kind of foxes are awarded the prizes. The American Association is really a national organization, for the members of its hoard of governors hale from all parts of the country. Recently Mr. Lewis has been honored by being made a governor of this association. Through him it will be possible for all fox breeders of the ex- treme West to keep in touch with the American Association and the latest de- velopments in this fascinating new indus- try.— J. H. Sanders, Truckee, Calif. WILD FOWL NEED PROTECTION AND FEEDING GROUNDS. Although legislative measures for the lirotoction of wild fowl have multiplied, and have added to the restrictions on hunters, these regulations have not been sufficient to maintain these game birds in their former abundance. Regions that once were the summer homes of myriads of wild ducks have been drained and placed under cultivation, and extensive areas where the birds at one time bred are now populous farming communities. These changes, say biologists of the United States Department of Agriculture, have crowded out the former feathered residents and have served in a corresponding degree to reduce their numbers. Realization of these facts has led recently to the adoption of other measures to encourage waterfowl. A number of extensive marsh areas have been made permanent refuges under the guardianship of the Department of Agri- culture, and many private preserves, some formed by artificial means, have been es- tablished where the birds are protected while nesting. In addition, in a number of cases, rigid local restrictions have been placed upon hunters. As a means of cooperating in such ef- forts to maintain and increase the num- bers of waterfowl, the Biological Survey of the United States Department of Agri- cult nro has undertaken investigations of the general conditions under which wild ducks live and thrive, coupled with counts of the birds found in areas varying in character. During three summers, field studies were made dealing with wild ducks in the Bear River marshes in Utah, a report of which has just been published by the department in Uppartment P.ullotiu !KU>. Wild Ducks and Duck Foods of the Bear River Marshes, Utah. During the three seasons devoted to thi'j work, twelve species of ducks and the Canada goose were found breeding in the region included in the Bear River marshes, which covers an extensive area at the northern end of Great Salt Lake. In an enumeration made during May and June, 1916, of the eleven species of breed- ing ducks, 3,650 pairs were counted, and it is believed that this number rei>resents between 60 and 100 per cent of the total number of breeding ducks occurring there that season. Allowing five young reared to maturity as the average for each pair, and considering 1916 as an average season, the bulletin states that, at a conservative estimate, between 25,000 and 30,000 wild ducks, native to the marsh, are to be found there at the close of the breeding season. It was found that, in addition to the large number of birds reared on the Bear River area, many other ducks came in after the nesting season to remain there until fall. That birds from the Bear River section range widely after leaving these marshes has been shown by records (f ducks that have been banded and re- leased there and subsequently were shot elsewhere. Records thus obtained show that birds released near the mouth of Bear River in migration cover the region from Oklahoma to Texas and west to California. The department urges the establishment of a greater number of preserves where CALIFORNIA FISH AND GAME 167 wild fowl may breed and rest unmolested, and find an ample supply of food. — United States Department of Agriculture. BIRD BANDING. The first American to become interested in the banding of birds was the great nineteenth century naturalist, Audubon, Curious to know what became of the birds that flew south with the approach of cold weather, he put thi-eads about the legs of a brood of phoebes that he had been watching and in the following spring was rewarded by having two of the birds re- turn to nest near the haunts where they had learned to fly. Bird banding is not confined to the banding of non-game birds alone. In the United States Department of Agriculture Weekly News Letter, of June ], 1921, there is the following in- teresting article on the banding of ducks : When a wild duck decides to move from his summer home in Canadian wilds he neglects to leave a forwarding- address to indicate where his winter quarters are to be established. The Bureau of Biological Survey, United States Department of Agriculture, is working on a method to offset the duck's carelessness. This con- sists of a system of trapping the birds and marking them with aluminum leg bands that carry a number and the legend "Biol Surv., Wash., D. C." When a banded duck is killed, the hunter removes the band and returns it to the Biological Survey with information show- ing when and where the bird was re- covered. During the past autumn a Canadian collaborator of the Survey, Mr. H. S. Osier, operated a duck trap at Lake Scugog, Ontario, where he captured and banded over 200 black ducks and mal- lards, with a few ring-necked ducks and blue-winged teals. Some of these were killed near the place where they were banded, but others were from such localities as to indicate approximately the route taken by these birds in their journey to the Southland. In all, about 25 of Mr. Osier's ducks have been killed and the bands returned from points in Ohio, Indiana, Kentucky, Tennessee, Arkansas, Mississippi, Louisiana, and Texas. One of the blue-winged teals was killed near Port of Spain, Trinidad, British West Indies, more than 2,500 miles from Lake Scugog, where the band was attached. The systematic banding of birds, as undertaken by the Biological Survey, will furnish conservationists with much valu- able information. 168 ' CALIFORNIA PISH AND GAME FACTS OF CURRENT INTEREST. Deputies Clark and Burke arrested six Japanese near Pigeon Point, San Mateo County, for having 150 undersized abalones in their pos- session. These men were notified to appear before Judge Ray Grif- fin, which they did, and were fined $100 apiece. Mr. Jay Bruce, state lion hunter, succeeded in killing nine mountain lions during the first three months of the year, as well as three bobcats. Deputy Von Arks made cases last year within a five-mile radius of his home, in Sonoma County, which brought in fines aggregating thirteen hundred dollars. Deputy Von Arks evidently believes in cleaning up his home town first. During February and March there was a round up of violators of the fishing laws in district twelve. Sixteen men were arrested of whom six were convicted, the fines totaling $695. Four nets totaling 667 fathoms were confiscated. Two of them were sold and netted $145. During March deputies 0 'Council and Newsome confiscated seven nets, totaling 2295 feet, which were being illegally used in a closed district. Deputies Groves, Lencioni, and Von Arks, working the coast be- tween Russian Gulch and Wallalla at low tide, arrested sixteen vio- lators for having in possession undersized abalones. The off'enders were taken before Judge Charles of Sea View and the fines will aggre- gate over seven hundred dollars. The largest fine was one hundred and twenty-five dollars, which was awarded a market fisherman. The small sized abalones confiscated totaled several hundred. CALIFORNIA FISH AND GAME 169 HATCHERY NOTES. W. H. SiiEBLEY, Editor. As the egg-collecting operations at the various hatcheries have not been entirely completed yet, we are, consequently, un- able to definitely submit the number of trout fry which will be available for dis- tribution from the various stations during the coming season. We anticipate that the output from all of the hatcheries of the state for the year 1921 will be ap- proximately 25,000,000 trout fry. If the number of trout fry actually distributed even approximates this figure, it will be the largest distribution of fry ever made in one season in the state. Due to adverse climatic conditions in some sections of the state, we did not take as many eggs at the spawning stations as we had anticipated ; but this partial failure is, in a great measure, offset by favorable situations obtaining in other dis- tricts. MOUNT SHASTA HATCHERY. From present indications, we will have for distribution from Mount Shasta Hatchery this season, approximately 11,- 000,000 trout fry consisting of rainbow, Loch Leven, German brown, eastern brook, steelhead, and possibly a small number of black-spotted trout fry. The Loch Leven and German brown and practically all of the eastern brook trout eggs were taken from the adult fish kept as a breeding stock in the Mount Shasta Hatchery ponds. The rainbow eggs were received from the several rainbow egg- collecting stations located on tributaries of the Klamath River, Siskiyou County. In addition to the rainbow eggs hatched at the Mount Shasta Hatchery, a sufficient supply of eggs of this specie were re- ceived to permit of shipments being made to Mount Whitney, Ft. Seward, Kaweah and Wawona hatcheries. The supply of steelhead trout eggs which is being hatched for distribution from the Mount Shasta Hatchery was received from the Brookdale and Ukiah hatcheries. The two fish distributing cars are in the shops of the Southern Pacific Co., at Sacramento, being overhauled and placed in first-class condition for the season's op- erations. The work on the two cai's is )ractically completed and at least one car will be ready for commencing the season's perations on or about June 1. Distribution operations from the Mount hasta Hatchery will be commenced nearly a month earlier than is usually the case. t was essential that we commence this work earlier than in former years owing 0 the greater number of trout fry which yve will have to distribute from that sta- iou this year. As mentioned in a previous issue of California Fish and Game, there were hatched at the Mount Shasta Hatchery his season nearly 6,000,000 chinook sal- mon eggs, which were received from the Federal Bureau of Fisheries' station at 'Mill Creek and from our own salmon egg- collecting station at Klamathon, on the Klamath River. As soon as the oldest of the salmon fry were of suitable age for planting, they were distributed in the liead waters of the Sacramento River and the balance of 3,000,000 were removed rom the hatching troughs and placed in the three large salmon rearing lakes on the Mount Shasta Hatchei-y grounds. These fry will be fed and held over the ummer and released in the head waters f the Sacramento River during the fall months. FALL CREEK HATCHERY. Rainbow egg collecting operations at the Fall Creek Hatchery were very successful, there being nearly 1,000,000 eggs of this specie collected. Approximately 600,000 of the eggs have been hatched and will be held throughout the summer months and c'istributed in the Klamath River at the I roper season. The balance of the eggs were shipped to the Mount Shasta Hatch- ery to be hatched and reared for distribu- tion in other localities of the state. In addition to the rainbow trout hatched at Fall Creek station, 3,000,000 of the salmon eggs collected at Klamathon Hatchery last fall were hatched and are being reared for distribution in the Kla- laath River. A portion of the fry will be planted during the late spring months and I the balance will be held in ponds con- Ifitructed for the purpose last summer, and 170 CALIFORNIA FISH AND GAME cno aflditional pond which is now in course of construction. These fish will be held and fed throughout the summer and dis- tributed in the Klamath River next fall. BOGUS CREEK STATION. Bogus aud Camp Creek egg-collecting stations have been closed after completing the most successful season since the sta- tions have been established. Over 6,000,- 000 rainbow trout eggs were collected from these two stations during the sea- son which has just closed. All of the eggs collected were shipped immediately to the Mount Shasta Hatchery for incuba- tion. During the summer some minor re- pairs aud improvements will be made at these plants in order that they may be in readiness for operations next season. HORNBROOK STATIOfJ. The Ilornbrook station was operated during the past season, but the number of eggs collected was far below the normal take, less than 200,000 eggs being taken during the entire season. This was due to the fact that the flood waters of the early part of the spawning season changed the course of Cottonwood Creek, forming a sandbar between the old mouth of the stream and the new cut, which prevented the trout from entering the stream to spawn. Prior to the cutting of the new channel, the flood waters were entirely over the top of the racks, thus permitting the first part of the run of spawning fish to pass on up the stream. The small number of eggs taken were received from the few stragglers which came up the creek through the old channel. Before the station can be successfully operated, it will be necessary that consid- erable work be done in opening up an adequate channel to permit the fish to ascend the stream at the mouth of the creek. MOUNT WHITNEY HATCHERY.. During the early part of December, 300,000 Txtch Leven trout eggs were ship- ped to Mount Whitney from Mount Shasta Hatchery and during the first part of April, 500,000 rainbow trout eggs were shipped from the same station. Ship- ments of steelhead trout eggs to the num- ber of 800,000 were made to the Mount f\''hitney Hatchery from Brookdale Hatch- ery. The fry resulting from these three hipments of eggs are developing into fine, healthy fish, aud will be ready for dis- ribution early in the summer. Further shipments of rainbow trout eggs will be made from one of the other tations and we are also contemplating ()l)ening up the Rae I-akos rainl)o\v egg- callecting station. All eggs received from his source will be immediately transported 0 the Mount Whitney Hatchery, where Ihcy will be hatched and reared. LAKE TAHOE HATCHERY. The new Lake Tahoe Hatchery, which was completed last fall, was opened for operations on May 14. A shipment of black-spotted trout eggs was taken to the hatchery on that day from the new egg- ollecting station established on Black- \;ood Creek. Other shipments of black- potted eggs will be forwarded as the eggs are taken at Blackwood Creek. Ship- ments of steelhead trout eggs from the Brookdale and Ukiah hatcheries have been shipped to the Lake Tahoe Hatchery, and within the next two or three weeks aiubow eggs will be shipped in from one ot the rainbow egg-collecting stations. MOUNT TALLAC HATCHERY. Mount 'Tallac Hatchery was opened for operations during March. As in former ears, seining opei'ations were conducted at the mouth of Taylor Creek, for the pawning trout from which are obtained the black-spotted trout eggs. In addition to the egg-collecting opera- tions conducted off the mouth of Taylor Creek, an egg-colleeting station was cs- ablished on the upper Truckee River. The stream was racked, and a trap, tank, etc., were installed. The results obtained from the operations to date have been very atisfactory. As above mentioned, a station was put n operation at Blackwood Creek and the ggs received from this plant are incubated t the Mount Tallac Hatchery and the new lake Tahoe Hatchery. One million black- B:)otted trout eggs have bceu taken to date. FORT SEWARD HATCHERY. The 500,000 thinook salmon shipped to '"■ort Seward from the Mount Shasta CALIFORNIA FISH AND GAME 171 Hatchery during February were hatched and the resulting fry distributed in Mad River, tributaries of Humboldt Bay, Eel River and other waters of Humboldt Coun- ty. This was done during the month of April. Two hundred and fifty thousand rainbow trout eggs were shipped to Fort Seward from Mount Shasta Hatchery on iNIay 16, and the resulting fry appear to be strong, vigorous fish. Over 800,000 steelhead eggs were shipped in from Ukiah Hatchery and these, together with the rainbow fry, will be given a wide dis- tribution in the waters of Humboldt, Mendocino and Trinity counties during the coming summer. SNOW MOUNTAIN STATION. Steelhead egg-collecting operations at the Snow Mountain egg-collecting station did not prove to be as satisfactory as was anticipated. Wbile there was a fair rain- fall in that section this season and other climatic conditions were favorable, the usual number of steelhead spawn fish did not reach our station. Consequently, we were unable to take the usual large num- ber of eggs. Approximately 2,000,000 eggs were taken as a result of the entire season's operations. We had expected to receive not less than 4,000,000 and pos- sibly 5,000,000 or 0,000,000. A thorough investigation as to the reason for the fail- ure of the spawning fish to ascend the stream to the Cape Horn dam, where our station is located, resulted in our finding that the stream had been blocked by fences, cleverly arranged in the Eel River, some distance below our stations. These had been constructed by persons who wished to prevent the fish from ascending the stream, in order that they might catch them. Those responsible for this outrage should be prosecuted to the full extent of the law, particularly since the legislature has just passed an act making it unlawful to bar the passage of fish by any weir, fence or obstruction. The eggs taken at Snow Mountain sta- tion, with the exception of about 200,000, which were hatched for distribution in the upper waters of the Eel River, were im- mediately transported to Ukiah Hatchery. UKIAH HATCHERY. The Ukiah Hatchery was opened for operations on March 19. A total of 3,859,000 eggs were received from the Snow Mountain station. These were yed and shipments made to the Fort Seward, Mount Shasta and Lake Tahoe hatcheries. Between 500,000 and 600,000 teelhead eggs will be hatched at Ukiah Hatchery for distribution in the streams f Mendocino and Sonoma counties. SCOTT CREEK STATION. Egg-collecting operations at Scott Creek tation have been the most satisfactory ince the station was established. Three million steelhead trout eggs have been col- ected and operations have not as yet been ompleted. There will probably be some- hing over 100,000 eggs yet taken. All e?gs were transported to the Brookdale Il\atchery as soon as the fish were spawned. BROOKDALE HATCHERY. As stated above, the Scott Creek sta- ion produced well over 3.000,000 steel- head trout eggs, all of which were trans- jorted to Brookdale Hatchery where they have been eyed and shipments of eggs uade to the Mount Shasta, Mount Whit- ney, Lake Tahoe, Wawona and Kaweah hatcheries. In addition to eggs shipped cut to the above named stations from the Brookdale Hatchery, approximately 900,- 000 steelhead fry will be reared for dis- ribution in Santa Cruz, Santa Clara and San Mateo counties. Arrangements are ')eing made for the shipments to these three counties. DOMINGO SPRINGS HATCHERY. Domingo Springs Hatchery was opened or operations during the middle of March nd preparations were made for trapping iie run of rainbow trout ascending Rice Creek to spawn. Severe storms in hat section made it very difficult for the lien to get into the station. They were obliged to go in over fourteen feet of snow n some places. The heavy snow did considerable dam- ,ge to the racks and traps at Domingo -Springs Hatchery, and also to the fish- c ilture equipment installed at the mouth 01 Warner Creek last fall. It is our in- tention to operate at Warner Creek this B'ason, in conjunction with the Domingo Springs Hatchery, where all eggs secured rom the former plant will be incubated. At this date no eggs have been taken at 172 CALIFORNIA FISH AND GAME Domiufro Springs or Warner Croek as tlip "run" of spawning fish from Lake Al- nianor is very late, but we anticipate a very successful take of eggs. CLEAR CREEK HATCHERY. The (Mear Creek Hatchery was opened for operations during the middle of March, as were the Domingo Springs and Warner Creek stations. Egg-collecting operations are somewhat earlier at Clear Creek than at Domingo Springs and to date we have secured approximately 1,500.000 eggs. A portion of the eggs secured from the Clear Creek and Domingo Springs hatcheries will be hatched at these two stations to supply local streams with trout fry, and the available balance will be shipped to the new Feather River experimental station. FEATHER RIVER EXPERIMENTAL STATION. As mentioned in a previous report, we are establishing an experimental hatchery on Jamison Creek, a tributary of Feather River. The station is located between Blairsden and Johnsville. in Plumas County. The ])urpose of (stal)lishing a station at this point is to eliminate, to a great extent, the necessity of transport- ing trout fry from the Mount Shasta Hatchery to stock the waters in this dis- trict, as well as the district along the Yuba River, in the vicinity of Sierra City. Eggs will be shipped to this hatchery from the Domingo Springs and Clear Creek stations. The first shipment of 200,000 eggs was delivered from Clear Creek Hatchery on May IG. On May 14, a shipment of 100,000 steelhead trout eggs was i-eceived from the Ukiah Hatchery. The eggs appear to be in first class con- dition. As soon as the eggs commence to hatch, we will be better able to determine what the outcome of the experiment will be. If there is no loss of fry or ei<;s. ad- ditional eggs will be shipped to the sta- tion and this large territory will be sup- plied with trout fry from the experimental hatchery during the coming season. NORTH CREEK HATCHERY. Egg-collecting operations at North Creek station have been very successful. Eggs have been collected from the large rainbow trout ascending North Creek, Metcalf Creek, and Grout Creek from Bear Lake, and while operations at pres- ent are not complete, we expect to take 2,500,000 rainbow trout eggs this season. One million five hundred thousand eggs will be transferred from the North Creek Hatchery to the Bear Lake Hatchery, at Green Spot Springs, from which station the resulting fry will be distributed dur- ing the coming summer in Big Bear T^ake and various streams of San Bernardino County. The North Creek Hatchery will also be operated to full capacity. The fry reared at this plant will be distributed in Big Bear Lake also. We also expect to have a couple of small shipments of eggs to send to the Mount Whitney Hatch- ery where they will be hatched for dis- tribution in other waters of southern California. WAWONA HATCHERY. Tiirei' huiidri'd lliimsand rainbow eggs. and 100,000 steelhead trout eggs from l>rookdale Hatchery, have been shipped to i^/awoua from the Mount Shasta Hatchery and the resulting fry will be distributed in Merced River and other streams of that section during the coming summer. Previous to opening the Wawona Hatchery for operations on April 23, cer- tain necessary repairs were made to the flume and water distributing system at the hatchery. All tlie repairs could not be finished this spring, consequently, we will Lave to complete the work after the fry have been distributed during the summer. KAWEAH HATCHERY. Owing to the fact that we were unable to proceed with the construction of the jiermanent hatchery on the Kaweah River, it was necrssary that we again operate the small experimental station established three yeare ago near the town of Ham- mond. Three hundred thousand rainbow rnd 100,000 steelhead trout eggs were ;hil)ped to Kaweah Hatchery and the re- ulting fry will be distributed in the waters of Tulare County, as has been our ractice during previous seasons.

The past session of the State Legisla- ture was remarlvable in tliat tlierc were fewer fish and game bills for the Fish and Game Committees to consider than for many sessions. Most of the bills intro- duced proposed only minor changes in al- ready existing laws. The opinion is quite general that the present game and fish- eries laws are fair and in the interest of conservation. There is also a stronger inclination for the legislators to seek and accept the advice of those of the Fish and Game Commission who have made a study of the fish and game conservation prob- lems. .The few bills affecting the commercial fisheries which finally were passed were all good bills and received the signature of the Governor. These bills become laws on July 29, 1921. The following is a brief summary of the fisheries bills which were signed by the Governor, taken up in the order of their introduction : Ssnate Bill No. 265. By Senator Rigdon. Ahaloxcs uiid Clams. Amends the present law, section 628/ of the Penal Code. Reduces the daily bag limit on Pismo clams from 30 to 15, but permits ship- ment and sale. Changes the abalone sea- sons by making a uniform closed season for all species of abalones from January 15 to March 15. Raises the minimum size limit on red abalones, which may bo taken for commercial purposes to eight inches in greatest diameter. Restricts the commercial taking of abalones in dis- tricts 10 and IS to the territory lying outside of a line twenty-five feet beyond low tide mark. The minimum size limit on red abalones which are taken from the shore to twenty-five feet beyond low tide mark, remains at seven inches in greatest diameter, but the number of any species of abalones which may be taken from this inshore area must not exceed ten per day and they must not be sold. It is expected that this law will greatly reduce the commercial taking of Pismo lams and give visitors to the beaches where these clams are found an ojipor- Inuily to gatlier cnDUsli f(ir their own use. t is hoped and expected that the changes in the abalone law will permit the full utilizatiim of tliis valuable food rrsourcc^ ud provide enough abalones for those who )refer to gather their own from the shore. Senate Bill No. 576. By Senator Rominger. Fish Ix'cdiictioii. This hill amends section 5 of the act egulating the use of fish in reduction plants, etc. The present act, which was i)assed two years ago. intended to give the Fish and Game Commission full power to regulate the use of fish in reduction plants, but in a recent friendly suit in Los Angeles to determine if it did give the power intended, \t was the opinion of the court that it did not. Therefore, faction 5 was amended and enlarged so rs to prohibit direct fishing for edible fish or reduction purposes and to prohibit 1 iking any fish in excess of what can be onverted into human food except by spe- cial application to and permission from he Fish and Game Commission. Such xcess of catch can not in any case exceed 25 per cent of what is used for human food. Senate Bill No. 644. By Senator Lyon. Ktl/i ltd rn xliiiij. A new act which supplements an act regulating tlii> cutting and harvesting of kelp. The i)resent law worked al! right dur- ng the period of the war when kelp potash brought a very high price, nuiking it i>rof- table to cut the kelp and transport it long istances to the reduction plants. The onditions are different now and all of the clp companies have ceased to operate. ^'he price of potash has fallen to such a liunre that it will not pay any company (> engage in the kelp reduction industry I nless by-products in addition to potash cm be made use of and even then they •annot operate i)ro!itably unless they are ssured of a continuous supply of kelp CALIFORNIA FISH AND GAME 175 close at hand. Under the old law any licensed company could cut kelp on any of the beds which had been declared open for cutting by the Fish and Game Com- mission. The result of this arrangement was that many companies wished to cut in the beds located near the better harbors and these beds were quickly exhausted, compelling the companies to frequently go long distances for their supply of kelp. It was to encourage the reestablish ment of the kelp industry by leasing to a com- pany those kelp beds or positions of beds which lie close at hand, that this bill was drawn. Senate Bill No. 811. By Senator Scott, Shrimps. Amends section 628 of the Penal Code. Provides that the unmarketable shrimps which are taken in district 13 (South San Francisco Bay) while fishing for the fresh shrimp market, may be dried. After much experimenting it has been found that the small shrimp unsuitable for the markets, cannot be screened out and returned to the water alive as was in- tended under the old law. The shrimps are easily screened after cooking for they are then doubled up and the small ones screen out, but efforts to screen them be- fore cooking failed. The smaller shrimps are perfectly good for drying purposes and this law will prevent a considerable waste and possibly result in a reduction in the price of fresh shrimps. Assembly Bill No. 485. By Mr. Gray. Districts. Amends the act dividing the state into fish and game districts. The changes in this act which will af- fect commercial fishing are : District 7 is extended to the south line of Mendocino County in order to take in the salmon trolling territory at Fort Bragg and Shelter Cove which need dif- ferent regulations from the rest of district 10 in which they were before. (See under Assembly Bill No. 832.) Vallejo Channel and the lower end of Napa River are stricken from district 12 B, thus throwing them into district 2, where netting is prohibited. The southern limit of the netting dis- trict, 12 B, is placed at the right of way of the Santa Fe Railroad instead of the soufli boundary of San Joaquin County. Xftling soulh of the Santa Fe right of way is prohibited. Districts 20 and 20 A (Catalina Island) re changed. District 20 will extend from South East Rock to Lions Head, taking in about two-thirds of the waters on the ast and northeast side of the island. Dis- trict 20 A will consist of the remaining tate waters surrounding the island. Jnder the provisions of Assembly Bill No. 831, netting is permitted in district 20 A, but in district 20 netting is not only unlawful but the possession of nets in the district is prohibited. Assembly Bill No. 830. By Mr. Stevens. Striped Bass; Shad. Amends section G28 a of the Penal Code. Closes the fall netting season for striped bass and shad on September 17, instead of September 25, thus conforming 0 the new closing date for salmon net- ting. Provides that no more than five salmon may be taken per day in district 2 and pro- hibits taking striped bass less than twelve inches in length with hook and line. The minimum size which may be taken with nets remains at three pounds. Pro- hibits the possession or sale of striped bass weighing more than ten pounds, dur- ing the months of April and May. Provides that striped bass which are legally taken during the open season may be held through the closed season of June and July under regulations to be pre- scribed by the Fish and Game Commis- sion. Assembly Bill No. 831. By Mr. Stevens. l^cts and Lines. Amends section 636 of the Penal Code. Provides that gill and trammel nets of not less than seven and one-half inch mesh may be used for salmon only during the months of June and July in district 12 B. Prohibits the possession of beach seines, ouud-haul or purse nets in districts 12 nd 12 B. Piohibits the use of fyke nets for taking cat fish. Permits the use of crab traps in those districts where crab nets are allowed. Prohibits the possession of nets in dis- trict 20. 176 CALIFORNIA FISH AND GAME Assembly Bill No. 832. By Mr. Stevens. Salmon. Amends section 634 of the Penal Code. This bill is of importance for it places further restrictions on the taking of sal- mon which show that they are in need of additional protection. The suggestion for salmon conservation made in the last issue of California Pish and Game wore largely followed in this bill. The rapid increase in the catch by outside sea trolling, left the salmon insufficiently pro- tected. It was the object in this bill to cut duwu the catch about equally in all districts and not cut down the river catch alone as suggested by the outside trollers, or cut down the outside catch alone as suggested by the river fishermen. The upper Sacramento River district 12 A netting season was reduced fifteen days so that the open season for that dis- ti'ict is the months of January to April, in- clusive. For the balance of the river, the fall netting season was closed eight days earlier. These eight days are taken from the time when the run is heaviest and amounts to much more than the short time would indicate. This provision will cut down the river catch a little over 10 per cent. A closed season is provided for Monte- rey Bay of January, February and March, which will cut down the catch in pounds at that point about 10 per cent. As this season comes at a time when small, im- mature salmon are taken in numbers the saving in numbers of fish is more than the saving in weight indicates. A closed sea- son from March 1 to April 15, is pro- vided for district 10 and a closed season of March and April for district 7. These two last are outside trolling districts and the closed season is to protect the imma- ture salmon which are caught at the be- ginning of the season. The bill provides that Eel River be closed to the use of nets after January 1, 1922, but permits the commercial tak- ing of salmon on the lower river by trolling during the months of September, October and November. Assembly Bill No. 1015. By Mr. Benton. Croakers, Halibut and Barracuda. Amends section 628 e of the Penal Code. I'rohibits the sale of California whit- ing, yellow-fin and spot-fin croakers. The sale of California halibut under four pounds in weight, or of barracuda under three pounds in weight or of albacore un- der six pounds in weight is prohil)ited as in the old law. In addition to the non- sale of these last three kinds of fish, this hill prohibits the possession of over fifty pounds of undereized fish. FISHERIES NOTES FROM SAN PEDRO lOiglit lishcrmou were arrostfd and con- victed during April and May, 1921, for violations of the state fish laws ijertain- ing to district 20. One of the heaviest fines imposed was meted out to Tony Marincovich, a San Pedro fisherman, in the justice's court at Avalon, Catalina Island, on May lo, 1921. Defendant in this case was fined $500 with the sus- pended jail sentence of one hundred days for maintaining a net in district 20 in vio- lation of section 636. The first albacore taken by a local boat this season was brought to San Pedro on June 8. Six fish averaging about sixteen pounds each were taken with jig lines. The new fireproof cannery of the Half- hill Packing Corporation, recently com- pleted on Channel 3 at Long Beach, is being i^ut in readiness for the tuna sea- son. In the meantime this company will pack chicken. A decision that may affect the com- mon practice by canneries in receiving tuna "subject to condition after cooking," was given by Superior Judge C. S. Crail ;it Department 4 in Los Angeles on June 9, in action brought by the crew of tlie "Golden Gate" for fish refused as unfit for cauning purposes. Judgment was granted in favor of the plaintiff for seven and one-half tons of spoiled fish. This decision may result in fishermen taking more care with their catches on account of the possibility of canners refusing any fish that looks douijtful. The boat "Kotobuki," Captain M. Vamamoto, arrived in San Pedro on June 13, with eight and one-half tons of sea- weed {Oelidium sp.) taken in Mexican waters. The entire load was consigned to the American Agar Company in Glen- dale, California, which company is en- CALIFORNIA FISH AND GAME 177 gaged in manufacturing agar-agar. Tliis seaweed was talcen near Point Banda in approximately tliree to four fathoms of water by means of hooks attached to long poles. PACIFIC FISHERIES SOCIETY MEETING. The Pacific Fisheries Society will hold its annual meeting at the University of Califoi'uia, Berkeley, on August 4, 5 and (i. Some interesting papers will be read and discussions held on the development and conservation of the commercial fish- eries as well as on the subject of sport fishing. The meetings will be of interest to those engaged in the fishing industry as a business, as well as to those inter- ested in problems of conservation, for an effort will be made to get these two fac- tions into close touch with each other. The final program will be announced about the middle of July. Some of the papers will cover the following subjects : Whales and Whale Fisheries of Cali- fornia ; Seals and Sea-lions of California and their relation to the Fisheries ; Fish- eries Investigations of the California Fish and Game Commission ; Future of the Pacific Coast Salmon Industry ; Relation of Hydro-electric Power Development and Irrigation Projects to the Salmon Indus- try and to Trout Fishing; Fish Canning and Inspection ; Fisheries Schools, etc. The affiliated societies of the Pacific Division of the American Association for the Advancement of Science will also meet at Berkeley during these three days. The public is invited to these meetings. Papers relating to the fisheries will be given before several of these societies and any one attending the meeting of the Pa- cific Fisheries Society will have an oppor- tunity to hear them. Saturday, August 6, will be given over to many field excursions to visit places of scientific interest and to visit the lo- cal fisheries. Further information may be obtained from the secretary of the Pa- cific Fisheries Society, Mr. George F. Sykes, Corvallis, Oregon, or from the De- partment of Commercial Fisheries of the Fish and Game Commission at San Fran- cisco. STATE FAIR EXHIBIT OF FISHERIES The Fish and Game Commission has secured twenty-four by forty feet addi- tional space in the main exhibit building at the Sacramento State Fair and will enlarge the scenic and live fish display which has been one of the most attractive exhibits at the fair during the past two years. An area of sixteen by forty feet will be devoted to an educational exhibit of the state's fisheries resources and to the fisheries conservation work of the commission. NOTES FROM THE STATE FISHERIES LABORATORY.* Will F. Thompson, Editor. THE PERSONNEL. The Fish and Game Commission has lost the services of Miss Helen M. Ed- wards, who married Mr. Samuel Bacon the latter part of April. Miss Edwards has been acting as scientific assistant to Mr. Thompson during the stay at Hop- kins Marine Station, Pacific Grove. Her ♦California State Fisheries Laboratory, Contribution No. 28. The listing of small publications of members of the laboratory force together with the Pish Bulletins issued by them has led to some confusion. Hereafter these will be numbered as sent to the printer, not according to the date of printing. The cor- rect numbers are as follows : Fish Bulletin No. 4, contribution No. 22. The Future of the Sardine, California Fish and Game, Volume 7, No. 1, contribution No. 23. Notes from the State Fisheries Laboratory, in California Fish and Game, Volume 7, No. 1, contribution No. 24. The Abundance of Young Pismo Clams, in California Fish and Game, Volume 7, No. 2, contribution No. 25. Quarter-oils or Half-pound Ovals, in California Fish and Game, Volume 7, No. 2, contribution No. 26. Whales and Sardines, California Fish and Game, Volume 7, No. 2, contribution No. 27. 178 CALIFORNIA FISH AND GAME place will be hard to lill, but neverthe- less, the best wishes of all with whom she has been connected in her work go with her. Besides Miss Edwards, the commission has had Mr. Thompson and Mr. W. L. Scofield at the Hopkins Marine Station during the past year, pending the con- struction of the new laboratory at San Pedro. In anticipation of the beginning of building operations, Mr. Thompson has transferred his residence to San Pedro. This has somewhat crowded the (luartcrs there as they are now constituted, but it is hoped that this will not be permanently the case. Mr. W. L Scofield has also left the Hopkins Marine Station, going to Palo Alto, where he will work at Stan- ford University for several months. This leaves no one at present in Pacific Grove. The Fish and Game Commission owes much to the Marine Station for the space kindly granted its workers. During the coming summer, Mr. O. E. Sette will be engaged in work for the commission in continuation of his sardine studies which he has been pursuing at Stanford University. He will make his headquarters at San Pedro with the other members of the laboratory staff. THE LIBRARY FOR THE NEW LABORATORY. The work of collecting a library for the scientific work to be carried on in the new laboratory has been under way some time. There have been many difficulties in the way, such as the unsettled con- ditions in Europe, the determination of the method of purchasing such periodicals as are desired, etc., but it is now hoped that the more serious of these have been overcome. There are now on our shelves the complete publications of the Scottish Fishery Board, together with those of the Irish and British governments ; the Re- ports and Bulletins of the Bureau of Fisheries of the United States ; the Re- ports of the Dove Marine Laboratory ; the Danish, Dutch and Norwegian govern- ment publications ; those of the Canadian government ; of the states of Rhode Island and Massachusetts ; of the Province of British Columbia ; and many separate volumes bearing on fishery matters. We have to thank the Dove Marine Labora- tory, Prof. E. E. Prince of Canada, the Danish, Dutch and the Norwegian Fish- ery authorities for their generous dona- tion of literature. There are now well toward completion the negotiations for the i>urchase of all the well-known scien- tific journals which are specially devoted to the subject of fisheries, and it is hoped that l)y the time the next issue of Cali- fornia Fish and Game appears, we will be able to record the arrival of many of these. The low exchange value of the money of various European nations has rendered the purchase much less expen- sive than would have been the case prev- ious to the war. It is unfortunate that some of the sets obtained, notably that of the Bureau of Fisheries of the United States, are some- what incomplete because certain numbers are out of print. We greatly desire to obtain these, however, and would be much obliged to anyone assisting us by the do- nation of odd issues of the various sets we may desire. — W. F. T. THE BASKING SHARK AT MONTEREY The Basking Shark, known to science as Cetorliinus maximus, has been recorded several times from Monterey, but its oc- currence is nevertheless an interesting event, especially to the fishermen. This giant shark, with its gill openings extend- ing well around toward the front of its throat, always attracts much attention when brought ashore. At Monterey it is usually taken in the lampara or gill nets, in which it becomes entangled until it is supposed to smother to death by the closure of the gill openings. It does great damage to the net in the meanwhile, and the fishermen do not welcome it. On May 3, 1020, a specimen was brought in to the wharf at Monterey, and measured by W. L. Scofield, who found it to be twenty-two feet long from the tip of the snout to the end of the tail. Again, in April, 1921, a specimen twenty-four feet in length was brought in by a lampara fisherman. In the endeavor to recoup some of the loss caused by the damage to his nets he exhibited the great shark for an admission charge. It is said that he failed in the venture. — W. F. T. CALIFORNIA FISH AND GAME 179 A RAG FISH AT MONTEREY. There are several "rag" fishes found on our coast, one of which is hereby noted as occurring at Monterey. Mr. Higgins has had the good fortune to find a still rarer member of the group, and describes it below. The specimen found at Mon- terey was Icosteus aenigmaticus of Lock- ington. It was taken during 1919, but the date and place of capture, save that of Monterey Bay, was not recorded. The specimen at hand is twenty-three centi- meters in body length, and twenty-seven and three-tenths in total length. The salient characters of this "rag" fish are its lack of stiff bones, which makes it much like a Aick, flat, bundle of rags, its yellowish color with purplish spots of irregular shape, and the row of spined scales along the lateral line. The fin rays are all of them covered by small spinules. It is very evidently a fish from the deep water, but just what depth we cannot surmise. It may be a pelagic. — W. F. T. A STRANGE RAG FISH AT SAN PEDRO. Closely related to the family of rag fishes, of which Icosteus is the typical genus, is the little known species, Acrotus iciUoughbyi, Bean. A specimen was taken in a mackerel net off San Pedro, March 31, 1921, and brought to the whole- sale markets. We were unable to obtain the specimen as it was sold for exhibition, but careful measurements were made and there can be little doubt of its correct identification. The fish was fifty-seven inches long, four- teen inches deep, and rather flattened lat- erally. The body was very limp and yielding as in other members of this group, due to the cartilaginous nature of the skeleton, the flesh was soft, and the naked skin tender and easily broken. The mouth was large, with thick lips, the nose broad and rounded, resembling with its large nostrils the muzzle of a calf. The fish was so fragile that it was somewhat mutilated when it reached the market, the gaff having torn through the jaw when landing the fish from the net. The first or type si>ecimen was taken in 1887 on the coast of Washington, appar- ently thrown up from deep water in a storm. Another was taken there subse- quently, and one was taken at Monterey. This occurrence is especially noteworthy as the species has rarely been seen by naturalists and has never before been taken on this part of the coast. — E. H. CUTLASS FISH TAKEN OFF LONG BEACH. Following the practice of noting the unusual, the occurrence of the cutlass fish, Trichiurus lepturus, Linnaeus, which has recently come to the notice of the labora- tory staff, entirely incidental to the reg- ular work, may be here recorded. Two specimens were taken, one on the first and another on the fourth of .Jan- uary, 1921, off Long Beach, in from three to five fathoms of water. They are each about two feet long, one and three-quar- ters inches deep, and very much com- pressed laterally. The mouth is large with long sharp teeth, the eyes large, and the skin is naked and of silvery color. The dorsal fin extends the length of the body to the long thread-like tail. The species is common in the West Indies, and has been reported on the At- lantic coast as far north as Cape Cod. It is known in the Pacific from Panama, Lower California, and Japan, but this is probably its first appearance in this region. — E. H. THE GRUNION. The traditional spring spawning runs of the grunion on the sandy beaches of southern California have created the usual excitement at Long Beach this spring. These little fish, as described by Mr. Will F. Thompson in Fish Bulletin No. 3, come up on the beach with the high tides of the second, third and fourth nights following the full moon of the spring months, to deposit their eggs in the sand away from their enemies in the ocean. Although the deposited eggs are free from most enemies, great numbers of the spawning fish are taken by the "grunion hunters," who gather on the beach at about high tide and capture the fish as they are left on the sand between waves. On March 23, the first night upon which a run might be expected, no fish were observed to be spawning. No ob- servations were made on the two follow- ing nights, but during the second sched- uled run, April 24, 25 and 26, large runs were observed on all three nights. 180 CALIFORNIA FISH AND GAME Runs were also reported to have oc- curred during the high tide of the new moon period early in May, but the ex- tent and dates of these runs are not known. The full moon run in May, seemed to be a little out of the ordinary, as on the firet night of the run, May 23, a con- sidcrable^stretch of beach was carefully watched, but no spawning fish were ob- served, only a small number being seen in the surf. The presence of the fish in the surf was also made evident by the capture of quite a number by the use of a net in the shallow waves. On May 24, the run was but little better than that of the night before. The many people who scanned the beach were able to col- lect a few fish by wading out into the shallow receding waves, but very few fish were observed to be spawning. The re- sults of a search for eggs in the sand on May 25, verified the conclusions from the observations of the two nights before, for only two pods of eggs were found as the result of quite extensive digging. The run of May 25 seemed to be normal in every way and many people who had searched the beach in vain the two previous nights were well paid for their lofforts with a good supply of fish. — H. B. H. LIFE HISTORY NOTES. INTRODUCED DOVE THRIVES IN LOS ANGELES. The Chinese spotted dove {Spilopelia chincnsis), as a resident of Los Angeles first came to my attention in 1917, when a dead bird was found by school children in Hollywood. The skin of this specimen was preserved and is now in the museum of the Nature Study Department of the Los Angeles County schools. At that time it was said to be common in a restricted locality in northern Holly- wood. Reports of its occurence have in- creased in frequency and from a much wider area, until in the first week of April, a bird was noted by the writer, at close range, near the museum in Expo- sition Park. Various reports as to the origin of this colony have not satisfactorily established whether the progenitors were liberated, or whether they were escaped cage-birds. The fact remains that the species is firmly established, and as a city-dweller, safe from hunters, is rapidly increasing in numl)ers. — L. E. Wyman, Museum His- tory, Science and Art, Los Angeles, Cali- fornia. MOUNTAIN LION SWIMS RIVER. It seems to be the general belief that the mountain lion is very shy of water, and that he will go out of his way in order to avoid crossing a stream when it is necessary for him to swim. My ex- perience in trailing lions does not bear out this impression. In fact, two male lions which I killed at different times in Shasta County were voluntarily swimming the McCloud River, at different places, on every trip around their beat. Deer were as numerous on one side of the river as on the other, so it was not neces- sary for the lions to cross in order to get food. And as in each instance, the tracks were several hours old, it is apparent that these lions did not swim the river to confuse or avoid the dogs, but that they were merely following their natural in- stinct. Another instance of this kind was in .January, 1921, when I was hunting from Kinsley Ranger Station, Mariposa Coun- ty, in the company of Mr. Joseph Dixon of the Museum of Vertebrate Zoology. After several days of storm, the weather cleared about dark on the evening of January 1!). There was about six inches of snow on the ground when w6 left camp early ou January 20. At about 9 a. m. we found the track of a large male lion on Crizzly Mountain. The tracks were about twelve hours old when we found them, which was indicated by the con- ilition of the snow where the tracks were made. On account of tlie dense brush in places we were unable to keep up with the dogs. As a result, by the time we had trailed the lion about six miles south to the north rim of the Merced River, and at a point about 2000 feet above the river, we CALIFORNIA FISH AND GAME 181 could just faintly hear the hounds bay- ing as they crossed over the south rim, at about the same elevation. We hur- ried down the mountain to the river and soon found the tracks of the lion and dogs entering the water on a sand bar at about 600 feet west of the mouth of Slate Gulch and about three miles east of Briceburg. I was sure that the dogs would tree the lion before night, so that I was deter- mined to follow them, although Mr. Dixon had had to return to Berkeley. As the river was about 100 feet wide and too cold and swift to swim with safety, I decided to build a raft. I stopped a pass- ing telephone lineman and got some spikes from him. Then I gathered some discarded railroad ties and driftwood and built a raft at the upper end of a pool. Using a piece of driftwood for a paddle, I ferried across. The dogs had crossed the river at about 12 o'clock noon and by the time I had built the raft and crossed to the south side it was 2 :30 p. m. I soon found the track of the lion and dogs climbing the mountain on the south side of the river. After trailing them about two miles up the ridge toward Fil- iciana, I heard the dogs barking "treed" in the head of a short canyon on the west side of Slate Gulch. When I arrived at the tree, the lion jumped out, but treed again about a hundred yards farther up the canyon. He was lying in the narrow fork of a tall live oak and when I shot him through the heart with the revolver, he sank into the fork and died. Then I climbed the tree and tried to dislodge him, but as he weighed about IGO pounds, and as it was necessary to lift the carcass about four feet to slip the hips through the fork, I was unable to free him. I then thought of cutting off one of the forks with my skinning knife. By this time, it was getting quite dark and a storm was threatening, and with a hard, rough trip of two miles down the canyon and the river to cross, I decided to cut the carcass in two be- hind the shoulder and drop the front half to the ground, leaving the rear half in the tree. By the time that I reached the river, it was quite dark and as the raft had drifted half way down the pool while I was crossing earlier in the day, I was forced to abandon the raft, on the return trip, near the north bank, and wade out to avoid being carried into the rapids. I now walked three miles down the river to Briceburg where I arrived about 8 p. m., after being on the trail fourteen hours. This lion had crossed the river prob- ably ten hours ahead of the dogs and was following his regular beat as I found his old tracks while trailing him on the south side of the river. There was also the skeleton of a calf near the place where the lion was treed. He had probably been killing cfittle there during the sum- mer.— Jay C. Bruce, San Lorenzo, Cali- fornia. CURLEW NUMEROUS. Since its protection, the Hudsonian curlew {Numenius hudsonicus) is becom- ing more numerous again, in this vicinity. I have lived and hunted in this country around Rio Vista from boyhood and have entertained a number of the most promi- nent sportsmen from many states on my reserve, and I have naturally taken a keen interest in the wild game life of the locality. I have heard the old settlers here tell how the jack curlews were upon these plains in countless thousands at one time. Whether they were killed off or inhabited another region, I am unable to relate, but I do know that for the last twenty years at this season of the year we have only seen an occasional flock. However, about a week ago I noticed a flock of about one hundred of these birds on the pasturage grounds each day. The flock has been increasing until it has reached about five times its original size. On April 2G, 1921, about sunrise, I saw a flock of about five thousand which all seemed to be whistling at the same time. I was greatly astonished, as I had never seen these birds in such numbers before. This large flock did not stop in this vicin- it}', but traveled straight on southward ; and each day I have seen curlew still mi- grating to the south, but not in such great numbers. There are a great many here at present, yet they are not so numer- ous as they were a week ago. They are evidently traveling to a new feeding ground.^ — S. C. Church, Rio Vista, Cali- fornia. 182 CALIFORNIA FISH AND GAME ALBINO DEER SEEN IN THE STANISLAUS FOREST. On February 1, of this year, Ranger Freer saw a white or albino mule deer in the Stanislaus National Forest. Sev- eral months later, on May 7, when Ranger Freer and former District Ranger Fowler were out repairing telephone lines they again saw an albino deer. These two records of the appearance of an albino deer were of unusual interest to us. — ^J. Y. WtJLFF, Sonora, California. A TRAPPER'S EXPERIENCES. I laid out my first line of traps on the twenty-fifth of October, 1920, stringing them from Logan Meadow north to the junction of the main and West Chiquito creeks, crossing here and keeping along the ridge until opposite Placer Station, where I crossed over and continued north to Arnold meadow. Then I crossed back to Ijogan via Mebold and Summit mea- dows, covering about thirty miles each day. Of course, I later varied this line in several respects, at one time running up the Joaquin to Squaw Dome, and again trapping the other side of the river as far down as Kaiser crossing. My first catch, on the twenty-sixth of October, consisted of three grey foxes and one skunk. All of these skins were ex- ceedingly blue and unprime, so I set all traps off that day and left them until the fifteenth of November, and even then I caught foxes that were not at all prime. In my mind there is not the slightest doubt but that the trapping season is at least one month too early even for that country ; yet there are always trappers at work on the first day of the season (October 15) as low down as Finegold. Then they wonder at the prices which they receive for their furs. For coyote bait I used squirrel meat ground very fine, to which I added a small amount of tincture of asafetida (God only knows how to spell that word— but you know what it is — I used to wear it around my neck to prevent diseases when I was a kid) and some oil of rhodium. I set three traps in a Y form, driving a stake through the rings completely out of sight, and covering the whole thing over very carefully. In the course of two months, I was able to so set such a group of traps that the coyotes would take enough notice of it to turn a trap over once in a while, or scratch the bait from the center of the set. I then found that thoy were suspicious of any set that was bounded on any side by any obstacle what- ever—and after that I set them in the openings ; and this was the secret of the whole game. I caught seventeen of these so-called coyotes in a very short time. A peculiar thing about them is that, while in the trap, at least, they will utter no sound whatever and, instead of striving to get away, they will simply grovel in the dirt like a domestic dog trying to beg forgiveness; also they will positively not meet your eye. On the contrary with the grey fox — they are continually on the prod and will growl, snap and bark from the time they see you until they are dis- patched. I also caught a large black eagle in one of these set«, and he was as docile as a chicken, not even hissing at me when I let him out of the trap. Later I caught another of these birds, but the coyotes found him first and left me only his two feet. I spoke to you about finding the car- casses of eight deer that had undoubtedly been killed by coyotes. These kills were always in the deep snow and one could visualize every move that was made. In each case the deer was chased by not more than two animals — sometimes only one— and caught by another as he circled back over his trail. I have always read that these animals hamstring a deer, but in so far as I could tell these deer were pulled down from in front by a nose hold, and when you take into considera- tion the size of these coyotes it does not seem at all impossible. My largest was sixty-two inches long and would weigh something over 100 pounds, but the aver- age was better than fifty-eight inches from tip to tip, and just that much bone and muscle. In broad daylight I saw one carrying a full grown badger by holding it in his teetli and throwing the weight over his left shoulder. When caught in a trap they will tear manzanita bushes over two inches through into the smallest shreds. The one thing I couldn't under- stand about these killings was that they were all large deer and mostly bucks. It was some little time after the rutting sea- son and after the bucks had plenty of time to regain strength. The last one I CALIFORNIA FISH AND GAME 183 found was about the twenty-fourth of February, and as I attempted to lift the head both horns came off in my hand. This for your information regarding the time deer drop their horns at that eleva- tion. This was a perfect four-pointer. During my stay in there I saw but one loin track, and though I followed for several miles I could not find where he had either attacked or molested any deer. I am, therefore, of the opinion that a great many of the kills with which lions are blamed should go to the coyote. J. T. Hogue told me that he had found a great many deer killed by lions in his time, but he admitted that he had seen no sign of a lion at a great many of these carcasses and had simply taken it for granted that it was a lion. When the Teafords were in there hunting lion and bear last win- ter they saw one lion track — this lion had come from Shake Flat across country to the Soda Springs on West Chiquito and straight through to Jackass — in a straight line and with never a stop, although he was passing through a country that liter- ally swarmed with deer of all kinds. Cer- tainly, at that time of year he was going straight through and out of the deer country, and though the boys followed him for two days he did not stop or make a kill of any kind. George Teaford and W. B. Day, both old-timers, tell me that they have seen deer killed by single coyotes — and since these animals of which I speak are not much smaller than the old timber wolf, it does not seem at all impossible. Unless the price of fur goes up to a point where it will pay to trap these coyotes, or until a bounty is placed on them by the county, it will be but a very few years before they do some real dam- age to the deer. Of course one wonders why they have not reached such numbers in the past as to have exterminated all of the deer, but I think that civilization is concentrating the deer and the coyotes into such a small tract of land in the h'lls that the coyote is gaining ad- vantages every year — especially during the hard winters. This same question is asked about the tree bettles — why they haven't destroyed all the timber before, since they were left alone for years — while I know there is a real reason I don't know what it is. As for deer — our fii^t few months in there we saw great numbers of does, and with every doe there was at least one fawn and sometimes two. Wagner told me that there were a great many barren does, but all the barren does I saw had their fawns close by. And that reminds me of another peculiar thing. There was a cave on the Logan side of the river where I thought there might be a bear or so, and while I was sitting there one day waiting for the dog to come up, so I could send him in, I saw an old doe and two fawns come down to drink on the other side of this river. It was the twenty-sixth of November and the deer had just started running, the first signs of this being on the twenty-fifth. This old doe led both fawns down and they started to drink. As soon as she saw they were busy at it she started up the hill on a dead run, but they heard her and caught her before she had gone 200 yards. She walked calmly back to the river with them again and started them to drinking again. This time she made her get away, although the poor little devils ran and bleated around there for half an hour, until they finally laid down under a big oak and tried to forget it. I do not know that this is the way the doe gets away from her fawns at this time of the year, but this I did see ; and I also know that after the season of mating is over she comes back to her fawns again. During November and part of December these little devils were all alone, but at the time we left the hills — February 27 — every doe had her fawns with her and seemed as loving to them as ever. The whole trip was the most interesting I was ever on, and I really believe I learned more about nature in those five months than during my entire life. I had an interesting experience with a skunk. It has been my belief that I was a regular skunk trapper and on this par- ticular day I found a large one in a trap on a sloping hill. The idea is that if you get their hind feet off the ground (their rear muscles being the ones that work the scent bag) you can kill them without smelling up the fur. I, therefore, lifted this fellow off the ground with a pole and hung him by one of the springs of the trap in a manzanita bush. I then walked up very close to him so as to be able to 184 CALIFORNIA FISH AND GAME shoot him through the brain. As I did so he reached cue leg behind him, got a purchase on one of the limbs of the bush and shot me square in the eye and ear, at the same time dropping down out of the bush, where he proceeded to work on me from the ground up. As soon as I had sufficiently recovered to open one eye, I took a squint at him and he was sitting there calmly chewing on the fish head with which I had baited the trap. This calm- ness of theirs impresses me more than anything else that they do, except, of course, the thing I have just mentioned. When you come on them in a trap they will invariably look up at you for an in- stant and then go on eating, or picking their teeth, or whatever it may be that they are interested in. After the twentieth of November the large bucks started to come down from the high country, though the spikes and forked horns had been running wild a week previous to this. After that the ground was torn up in huge chunks on every hillside and opening, in the entire forest. It was not my luck to see any real fights, though I heard one time a clashing of horns in the brush within thirty feet of the trail that must have meant trouble. Also, two of the last coj'otes that I trapped had large un- healed gashes in their heads and along their sides that could have been made by horns only. — Roy H. Blood, Madera, California. AN OPOSSUM SEEN IN PACHECO PASS. Last summer I was driving from Fresno to Monterey via Pacheco Pass, when about fifteen miles out from IIoI- lister and east of that place I saw some- thing which at the time I believed to be a cat. Although dark, I had a strong spot light and by using it 1 could see the shining eyes of the animal. I brought the car to a sudden stop and ran up to where it was lying, whereupon, it started to walk off. I grabbed a small stick and hit it lightly. It lay as if dead — it not only was playing possum, but it was a possum! It had the long slick tail which is similar to the tail of a rat. The hair was gray and white tipped and the face was the bald face of the opossum {Didel- phis virginiana) . I picked it up and held it for a few seconds, but it began to squirm and when I dropped it it ran into the shrubs at the side of the road and was gone. — II. D. T.ibby, Fresno, Cali- fornia. THE OPOSSUM IN VENTURA COUNTY P.eing a southerner and having had, last Xovomher, a fine opossum {Didclphis vir- f/iniana) killed by a friend, and baked with sweet potatoes in the true southern style by an old negro from Dixie, I was particularly interested in the item pub- lished in the January number of Cali- fornia Fish and Game. The opossum, a male, was killed in Ventura County, about two miles up the Snnta Clara River from the mouth and was the first one ever heard of in this vicinity. It was larger than any I ever saw in the south — California must agree with them. Since this opossum was killed, I have heard of two being caught near the line of Ventura and Los Angeles counties, but these were only reports. I did not see the animals myself. — Geo. P. Austin. Ojnard, California. CALIFORNIA FISH AND GAME 185 CONSERVATION IN OTHER STATES. MUSKRAT SEASON CLOSED IN MINNESOTA. In October, 1920, the department sent out thousands of questionnaires asking for information and an expression of opin- ion from trappers, fur buyers and dealers, farmers and sportsmen as to what steps should be taken to preserve a breeding nucleus of muskrats. Fully 00 per cent of the answers fa- vored an immediate closed season. The commissioner petitioned Governor Burn- quist for additional protection which was duly granted and order No. 2 was issued protecting muskrats until the close of the 1921 regular session of the Minnesota legislature. It developed later that muskrats were still numerous in some localities and complaints of the damage to highways and grades poured in so rapidly that the de- partment could not possibly investigate them all. Whereupon another petition was prepared asking for a lifting of the ban in thirteen counties. This was acted upon favorably by Governor Preus and order No. 3 was issued. — Fins, Feathers and Fur, December, 1920. SPORTSMEN'S CLUBS IN NEW YORK "There are today in New York some 475 sportsmen's clubs comprising a mem- bership of about 40,000 hunters, fisher- men, and other conservationists. Even this total, however, is smaller than it should be, in view of the fact that last year some 300,000 persons purchased hunting and trapping licenses in New York — to say nothing of the fishermen of whom no license is required." — The Con- servationist, April, 1921. INTEREST IN FISH AND GAME CON- SERVATION IN UTAH. Interest in fish and game conservation in Utah has been greatly stimulated through the efforts of the United States Forest Service, which has organized local fish and game protective associations and unified them into a state organization. Since October, 1920, more than twenty- five locals have been established. ANNUAL DIVIDEND FROM FUR- BEARING ANIMALS OF NEW YORK STATE. The game and fur-bearing animals of New York state, if capitalized, are worth not less than $53,000,000; they return an annual dividend of more than $3,200,- 000; and they cost the state for their protection and increase the nominal sum of $182,000. This cost of protection and increase is thus less than 6 per cent of the annual dividend. 186 CALIFORNIA FISH AND GAME REPORTS. VIOLATIONS OF FISH AND GAME LAWS. January 1, 1921, to March 31, 1921.

Thompson. In this number of California Fish and Game appear a series of articles upon the California sardine, dealing with the history of the fishery, the methods of catching, of canning, and the use of waste fish as fertilizer. They are not technical in nature, being designed for readers interested in fisheries in general, and do not attempt to speak authoritatively on debated points. The industry has been, for the past five years, an important one in California, and crucial years are ahead of it. It should be understood, in the first place, that the sardine packed in California is a true sardine, in the sense understood by scientists of recognized standing. This is not true of the "sardine" packed in Maine and other New England States. That is in reality a young herring, known to natural- ists as Clupea liarengus, whereas the true sardine is known as Sardinu pilchardus. This herring is caught in great numbers along the Maine coast in weirs, or traps made in relatively shallow water. Its habits are different in many respects from those of the true sardine, for the eggs of the herring are laid on the sea bottom and attach themselves Fig. 55. The California sardine, a specimen without the usual spots. Photograph by H. B. Holmes. there, while the eggs of the sardine are laid free in the water and drift with the currents. The differences in structure, flavor, etc., are ecpially marked. The same remarks may be made about the Norwegian "sardines" save for the fact that among them one finds two species of fish widely different from the true sardine, namely the young of the herring, and the bristling, or young of the sprat, called Clupea sprattus by European writers. It is noteworthy that the English courts decided in 1916 that Norwegian fish packed as "sardines" could not be admitted into England under that name. According to the review of the court, bristling had been packed in oil in Norway since 1874, and they were at first called ' ' Sproetten in oel, ' ' later ' ' Sproetten a la Sar- dine," and finally "Norwegian sardines." The name sardine was therefore limited to the young of the pilchard, which are canned in France, Spain, Portugal and Italy as sardines. The pilchard itself is canned in Cornwall as pilchard. Later the Australian courts fol- lowed the example of the English. ♦California State Fisheries Laboratory, No. 30. 194 CALIFORNIA FISH AND GAME The true sardine, or pilchard, is found rroni Enghuid along the Atlantic coast of p]nropi' soutlnvard into the Mediterranean, and the adjacent coasts of Africa. It has been divided into two races, or varieties, the one found in the Atlantic and known as Sardhni pilckarchs pilchardus, the other found in the jMediterranean and known as Sardina pilchardus sardina. It still remains to be carefully investi- gated whether the difference between these two subspecies, or varieties, or races, is less than exists between some of the other "species" of sardine. There are, indeed, throughout the world a nunil)er of these very closely related species of sardines. Thus there is the sardine of the Pacific Coast of America, from Alaska to IMexico, known as Sardina coerulea, and that of the coast of Peru, known as Sardina sagax, per- haps belonging to the same species, but more likely not. There is a gap of considerable extent between the extremes of their distributions, namely the tropical waters of the Gulf of Panama, and careful exam- ination of many specimens will some time be necessary to determine their distinctness. Nevertheless, they both are extremely closely allied to the sardine or pilchard of Europe, in habits, distribution in the sea waters, movements and structure. This is granted by every competent authority. They are the only true sardines found in the waters of the Americas, save, perhaps, a species found occasionally in the West Indies, for no sardine is found on our Atlantic coast. On the other side of the Pacific there are found the Japanese sardine, Sardinu melanosticia, and the Australian Sardina neopilchardiis. These are both very close to the European species. There is also a sardine to be found in the waters of the Cape of Good Hope, known as Sardina occllata. The interrelationships of these various species are very poorly known and the morphological characters upon which they are based are insufficiently studied. However, it is very plain that they are entitled to the name sardine, or pilchard, in contradistinction to the young of the herring, or sprat. Regarding their habits and rate of growth, not a great deal is known. It is known that the eggs are pelagic, tliat is, laid so that they float freely in the open ocean waters, and that the adults in the waters of Europe and America disappear before spawning. Whether they are subject to the great fluctuations in abundance to which the herring is, still remains to be seen. The California Fish and Game Commission has collected careful data which it is hoped will in due time throw light on the subject of habits, rate of growth, migrations, and the presence of great changes in abundance. If the results wdiich have been obtained in work on the herring can be paralleled, they will undoubt- edly prove of much importance. The following articles are regarded in no sense as a part of this w^ork, although they do, to a certain extent provide a basis for judg- ment as to the changes which may occur in methods of fishing and canning in the future. This is especially true of the article on fishing gear and methods. An article by Professor Starks of Stanford Uni- versity has appeared, in the April, 1918, number of California Fish AND Game upon the scientific characters of the members of the sardine and herring family found in the waters of California, and anyone interested is referred to that publication. CALIFORNIA FISH AND GAME 190 HISTORICAL REVIEW OF CALIFORNIA SARDINE INDUSTRY.* By Will F. Thompson. The sardine industry in California is, as it now exists, essentially a product of the great war. Previous to its outbreak there had been a relatively small pack at Monterey and San Pedro, but the machinery for a vast expansion already existed in part in the tuna canneries of southern California. With the practical cessation of sardine imports into the United States in 1915, and the later great foreign demand, the pack of California sardines rose to great heights. Now with the coming of peace and the gradual return to normal conditions still so far removed, it remains to be seen how our new industry will meet competition. The development of fishing and packing methods have thus far been incidents only in the thorough upheaval of 1914, and the history to be here recorded gives little clue to how well fitted they are for survival. So, in a measure, this review is not a history, because it is written during the event. Nevertheless, since the existence of methods, and a knowledge of the availability of the raw material, enabled the California sardine canners to so readily seize their great opportunity, the prewar period is of much interest. Failures and crudities naturally played their parts, as might have been expected, for a bodily transportation of fishing and canning methods from the great existing European and Maine fisheries was impossible. The California sardine is a true sardine, with vastly different habits than the young herring and sprat of the Maine and Norwegian fisheries. Where in Maine weirs may be employed, here nets must be used. And of course, the quality of the fish is also different, requiring different treatment. At the same time, the difference between French and American labor and physical conditions effectively pre- cluded the introduction of French methods of canning save in a general way. It is highly to be regretted that even at the time of the outbreak of the war, cannery methods were still imperfect and that such packs as that of the round can had still to be tried. THE PREWAR PERIOD. The canneries. The Golden Gate Packing Company of San Francisco was the first sardine cannery on the Pacific Coast. During 1890, 1891 and 1892 it put up 20,000 cases of sardines in quarter-pound cans of the usual type, 7000 cases of one-pound round cans, and 7000 of two-pound. But, so it was said, the appearance of the sardines was erratic, and this, combined with other eau.ses, resulted in the sale of the machinery, and its shipment to San Pedro, where sardines were to be found more consistently. There it was utilized by the Southern California Fish Company, managed by A. P. Half hill. This concern continued to pack sardines in a limited way until 1909, but in the meantime, in 1906, it had begun packing tuna, and toward this its energies were principally directed ♦California State Fisheries Laboratory, No. 31. 196 CALIFORNIA FISH AND GAME until 191G. Otlior eannories, sneh as the Lower California Fisheries Company, the Pacific Tuna C'annins; Company, and the Premier Pack- ing Company, all of San Diego; the Ilalfliill Tuna Packing Company, the South Coast Canning Company, and the Los Angeles Tuna Canning Company, of Long Beacli ; and the Van Camp Sea Food Company and the White Star Tuna Packing C-ompany of San Pedro, began operations on the tuna. So that in 191(3 there were ten firms engaged in packing this fish in southern California, with a long winter season when no tuna were available while sardines were. These firms pi'ri\i(lf(] i]\o fii'st great pack of sardines. In northern California no .sucli parallel industry liail prepared the way. Put F. E. Booth had, in 1903, started a cannery at Monterey, and in 1906, the IMonterey Fishing and Packing Company (later reorganized as the Pacific Fish Company) had established itself. ]Mr. Booth began in a small experimental way about 1902 in a shed on a back street in the town of ^lonterey. His real canning operations were begun in 1903 in a small luiilding on the waterfront where his cannery now stands. He started with rpiarter-oils and a little later packed larger fish, calling them mackerel, to suit the market then exist- ing. However, seven or eight years later, the federal government ruled that they would have to be labelled sardines. The early canning was done by the old method of hand flaking, drying in the sun, and hand soldering the cans. For the first three years there Avas not even a power winch for hoisting the fish from the boats to the cannery wharf. Fish were hoisted by hand, pulled up in ba.skets and carried in the same to the tank in the cannei-y. The pound oval pack which has become the specialty of the IMonterey canneries was developed under these normal conditions, and was well established at the outbreak of the war. So here, although but two canneries awaited the great expansion of the industry, they were on a relatively firmer basis, in so far as the sardine was concerned. In 1916, not only were the two existing firms kept busy, but a number of new canneries were started. The fishing methods. But, in northern California tliere had also develoi^ed a successful method of fishing, which provided a more uniform and cheaper supply of fish. This successful method was the use of the lampara.* There has been some controversy as to whether or not fishing before 1905 was done w'ith a gill net, and whether this was carried on during the daylight or at night. Gill netting, at present, is done in a small way for bait and for the fi'esh fish mai'ket. and lias lieen ]iracticed thus for many years at IMonterey. So it is possible that during the first year of experimenting the fish were supplied by the gill net fishermen. However, from 1903 to 1905 a pur.se net was used for sardines, for the most part in the daytime, usually in tlie afternoon, but occasionally at night. The fish were located hy seeing them .jump at the surface or by seeing schools in the shallow water. The cannery (F. E. Booth) furnished the equipment and the fishermen worked by the month for wages. ♦These notes regarding: the lampara are those of Mr. W. Tj. Scofielcl. who kindly made inquiries regarding the matter at the writer's request. CALIFORNIA FISH AND GAME 197 Instead of the modern lighter the "Sacramento River seine boat" was used. It was a light, double-ended boat, carrying the net and the catch. The seine was circled by hand from the skiffs, pursed from the seine boat or the skiffs, and pulled up between the fishing launch and the seine boat. The catch was dipped out and into the seine boat, about as at present. The net was made of one-inch mesh, from No. 6 cord, was twelve fathoms deep and two hundred long. There being no "bag," the fish were held by pursing the bottom by means of a rope run through rings. The net was extremely heavy because of the small mesh, and ten men were necessary. Hauls had to be made in shallow water, because the fish were almost sure to be frightened and to sink below the net if the water were deep enough. Fortunately the sardines could be found in shallow water a good part of the year. As the capacity of the cannery was only about ten tons, but one crew of ten to twelve men under a captain was employed during the first three or four years. The fishermen often failed to obtain a supply, and in 1905, the captain, Pete Ferrante, with Booth's backing, sent to Tangier for a lampara net, essentially similar to the one described else- where in this volume. This net had a bag of fine mesh in which the fish were trapped before they could sink, and it was easier to haul because of the coarse mesh in the wings. The purse seine and the lampara were at first used together, one for the day, the other for the night fishing, but in 1906 the purse net was abandoned because more expensive. Other lamparas were patterned after this first one, which soon went to pieces, and of course many modifications have been made since. But the use of the lampara soon enabled the fishermen to catch sardines in deep water and at night, when they could be located by their phosphorescence. The result was a larger and more certain supply. It can not be doubted that the lampara has played a most important part in the establishment of the sardine industry on this coast. In 1905 or 1906, the lampara was carried on the launch, and a barge substituted for the seine boat. Since then larger and larger launches have been used, with more powerful engines, just as in all other marine fisheries the methods of transportation have been steadily improved. The nets themselves have been deepened to fish more efficiently, and in southern California the type of net which the Japanese fishermen have modified from the lampara is thought by many to be a great advance. THE WAR PERIOD. Then, with two canneries packing sardines at Monterey, the tuna canneries awaiting a method of filling in the long winter season in southern California, and the methods of fishing already developed, there occurred the outbreak of the Great "War in 1914. It altered the sardine industry on this coast as thoroughly and profoundly as it did any other industry. First, in 1915, the domestic market was abandoned by the foreign packers to our own Maine and California industry, imports dropping sharply and continuously. Then, in 1917 and 1918, the European markets themselves were opened to our products by the derangements of supply, etc., in Europe, while with our entry into the war came the insistent campaign for food conservation, including .the 198 CALIFORNIA FISH AND GAME eating of fish rather than meat. The effect of foreign conditions npon our imports of "fish packed in oil" and our exports of "canned fish except salmon" is shown in Figure 56, taken from the reports of the Department of Commerce of the United States. This illustrates this point well, since sardines form the bulk of both categories. It will be noted that imports declined in 1915, but that exports did not rise until later.

To understand this change, however, the condition of affairs in Europe must be analyzed, and we may briefly review the history of the fisheries at Stavanger, Norway, where the packing of the Norwegian "sardine" is extensively done. In tlie lower part of Figure 57 arc shown the exports to the -United States. It is obvious that the fall is entirely parallel to that shown by Figure 56 for the imports into the United States, and that it was a fall of identical character in quantity as well as in value. TTowever, in Figure 57, the middle section sliows that the total quantity packed did not fall until a year or perhaps two j^ears later, and that the value of the packed fish did not fall until three years later, namely, in 1917. In other words, the market for Norwegian sardines was found in p]urope during the first years of tlie war, just as trade reports also indicate that better prices were obtain- able in the British and German markets than in the United States. This condition prevailed during 1915, and also to an even more marked degree during 1916, a year termed by the Norwegians the "golden year" because of the high prices, and despite the rise in cost of mate- rials and labor. But in 1917 and 1918 the exports to the United States and the total production both fell, because of scarcity of materials such as tin plate, olive oil, fuel oil, the prevalence of labor troubles, influenza and the placing of embargoes by belligerent countries. In 1917, for instance, there was a marked shortage of tin i)late, save where the factories supplying goods to Germany were provided with cans by that CALIFORNIA PISH AND GAME 199 country. These conditions continued and were intensified during 1918, so that, in contrast to 1916, it was termed a "dead" year. The effect of such changes as they affected the Norwegian canneries in passing, of great interest to us, as perhaps such changes as IS occurred to them may be apparent in the case of our own industry. The first result of the increase in price obtained was the founding of more canneries in 1916, and the later closure of many. Then there was Dollars 1.60 1.40 1.20 1.00 .80 .60 .40 .20 Thousands of dollars 1,400 1,200 1,000 800 600 400 200 Thousands of dollars 1,200 1,000 800 600 400 200 1912 1915 1919 ^'^ \ * \ >' \ t \ ,' / '\ \ y • 1 J •*■-._ / .^ / \ •v / 'y f* \' A \ \ / \ / \ -'' L \ / / 7 \ \ 1 / / / \ \ / f \ \ \ \ / / f / 6 / V N / \ \ \ \ \ 1 \ \ / \ / / \ / / / / / / c \ \ II II \ tj Percentage 80 70 60 50 40 30 20 10 Skjeppes 14 12 10 8 6 4 2 Millions of pounds 7.4 6.1 4.9 3.6 2.4 1.2 Percentage o f bristling used in total pack of sardines. — - — Value per Skjeppe (21.13 quarts) of material used.

Data from Supplement to the increased value per unit quantity of fish used, apparently not dependent upon the composition of the catch. Thus in the upper section of Figure 57, the percentage — among the total of herring and sprat — of bristling, or young sprat, which are supposed to provide the best pack of "sardines," is shown by the line of dots and dashes. It is obvious therefrom that the largest part of the war pack was made from the young herring and the blending, or mixture of sprats and herrings, and that not until the very small pack of 1918 did the percentage of bristling rise. And that very promptly fell upon the 2 — 14002 200 CALIFORNIA FISH AND GAME resumption of packing and export to tlie United States in 1919. But the value of raw fish per "skjeppe"* rose and fell in accordance with the value of the total. In other words, the war market was flooded with the pack of herrings and blauding, while the number of canneries first increased and then diminished. That some such conditions applied throughout Europe would seem to be true from the fluctuations which opcurrod in the importations from various countries into the United fStates. These are shown in Figure 58.

Data from Bureau of Foreign Commerce and Navigation of the United States. showed a decreased total in 1916, and a near collapse in 1918. Our consular reports show much the same to have occurred in Portugal as in Norway, namely, a first diversion of produce to European markets, then a general slackening of the industry, producing, in so far as imports into the United States were concerned, a nearly continuous fall. We may therefore summarize the causes of the fall in imports and the rise in exports as due to, first, the abandonment of the American market by European packers, and then the collapse of the European industry in part at least. American packers therefore were first offered a better domestic market and then a share in the European market in addition. The rise of the California industry. It will be seen that the most favorable conditions existed for our sardine fisheries, and the resultant effect upon the extent of our pack may be seen in Figure 59. Almost all sardines which are taken in this country are packed, and the increase in pack is clearly shown. The first great pack was, it is obvious, in 1917. And this corresponds with the great rise in value of sardines in this country, resultant in part from the conditions we have dealt with above, and in part from war conditions considered more generally in their effect on the domestic markets. At the same time we must remember the great encouragement •A skjeppe equals 21.13 quarts. CALIFORNIA FISH AND GAME 201 given to the use of fish during 1917 and 1918 after our entry into the war. In Figure 60, we have shown the rise in value of Maine, Nor- wegian, Portuguese and French sardines in so far as they were obtain- able in the Los Angeles markets, utilizing quotations on cases of a hundred quarter-pound oil sardines. When it is borne in mind that the California sardines were packed to meet the high values of 1917 and 1918, Figure 59 should be clearly understood.

Catch of sardines in millions of pounds, compared with catch of all fish in California durin war period. Data from reports of California Fish and Game Commission, 'save for 1915, which is froi reports of the Federal Bureau of Fisheries. The rise in value is shown in Figure 60 on a logarithmic scale, Avhich has the effect of making the rise of each commodity show as it M'ould if reduced to a percentage basis, and the slope of the lines is therefore comparable and truly indicative of the relative rise in value. An increase of a dollar a case of Maine sardines would plainly be a larger proportionate rise than a dollar a case of French sardines, yet the ordinary charts would show the two increases as identical amounts, but the logarithmic chart shows them as considered in relation to the first price, namely, a greater rise for the Maine than for the French in proportion. The figure demonstrates that the Norwegian sardine did not rise as fast as the Portuguese, save for a brief period in 1920, and that the Maine sardine fluctuated in price much as did the Nor- wegian. In so far as the French sardine is concerned, the sudden rise in price in 1914 and the subsequent practical disappearance we have not been a])le to analyze. We have no data on the California pack of quarter oil sardines which is comparable to these shown, because such a pack was not placed on the market until 1917. But there are shown the changes in value of Booth's Crescent one-pound oval pack, from 202 CALIFORNIA FISH AND GAME Monterey, and this shows much less rehative rise than the others utilized below. Just as the first flush of war prosperity and high prices in Norway in 1915 and 1916 resulted in the starting of eighteen new canneries, so in California the tuna canneries turned suddenly to sardines and Dollars 2.00 1.90 1.80 25.00 20.00 15.00 10.00 9.00 R.OO 7.00 6.00 i9i: 1914 1916 1918 1920 1921 ^== ^ ■^-^. booth: --c/iLiFi>/?n/a ~ ' 1 - 1 t A j3 \ 1- t- ' ^--^• — - / ■/?e/vcfi y P l^Jf'-' '"" —-\ - / / n^^f^' __; \ - /,. 1 // \i 0*7-^ / f ^\ /,-' r^DtS^ -\ - 1 1 J f f y -y y 1 ' "■■"' '' Fig. 60.

To illustrate this point, we have attempted to tabulate the canneries and the time of their construction or diversion to sardine packing, according to the year, with the following results: 1894' — 1 cannery built. 1903 — 1 cannery built. 1906 — 1 cannery built. 1915 — 1 cannery built. 1916 — 14 canneries start packing, 11 previously lunn. 1917—11 canneries built. 1918 — 10 canneries l)uilt. 1919 — 5 cannerie.s built. 1920 — 2 canneries built. Of course, some of these are no longer existent or have ceased opera- tions, but the point we desire to make is olivious, that there was a very considerable increase in canneries due to the value of the canneries, both for Monterey and for southern California, as contrasted with the much more modest rise in the pack produced, especially in southern California. It will be remembered that somewhat the same sequence of events occurred in Maine, when during the early days of the industry the canneries multiplied faster than the pack increased, until con.solida- tion and elimination took place. CALIFORNIA FISH AND GAME 203 But there was another parallel with the Norwegian pack perhaps not less important, although perhaps not due to the same causes. And that was the emphasis upon quantity rather than quality. Previous to the outbreak of the war the pound oval held the field, but for a time the round can cooked inverted and by steam took a very prominent 1916 1917 1918 1919 ( ( 1 1 1 1 / / / / r 1 > ( ( /^ / 1 1 ALL FISH CANNED IN CALIFORNIA BY CASES Northern Southern 191C_- 196.104 522,609 1917— 480.111 1,538,122 1918— 729.100 1,385,202 1919— 905,206 1,166,435 VALUE OF FISH PACKING PLANTS Northern Southern 1916-- $860,590 $948,702 1917— 786,197 2,573,453 1918— 1,569,330 4,089,660 1919-- 2,272,514 5,436,357 NUMBER OF EMPLOYEES IN FISH PACKING PLANTS Northern Southern 1916— 1,573 2,289 1917— 3,090 3.261 1918-- 3,829 4.210 1919— 3,123 5,119 1916 1917 1918 1919 NORTHERN CALIFORNIA - - - - SOUTHERN CALIFORNIA Fig. 61.

Introduced in 1916 by the Van Camp Sea Food Company, and widely adopted, this round can pack proved economical, and large amounts were shipped to Europe. But due to the emphasis upon quantity production its reputation was entirely lost. Other packs were subject to the same criticism, and far-sighted canners and brokers began to insist upon quality, foreseeing the failure of their markets under the more normal conditions sure to return in time. The National Canners' Association was asked to establish an inspection service and in 1917 204 CALIFORNIA FISH AND GAME this was done, as is related in another part of tliis issue. Under the stress of our entry into the war, the government for a time pnt the whole force of its inflnenec back of tliis in.spection service, in addition to a campaign of price fixing. At present the majority of southern California packers belong to it. By-products. An interesting part of the war demand was the high prices paid for oil, for fertilizer and for fish meal. Many of the canneries installed plants of their own for handling their offal, producing tlicrcfrom oil, and fish meal. But ultimately so much whole lisli w^as diverted to these j-)lants Avhen the profit was greatest that the matter became serious and attracted attention. The California legislature therefore passed a law in 1919 placing tlie control of the matter in the hands of the Fish and Game Commission. The effect was to decidedly reduce the percentage of fish diverted to this use, but in 1920 the market for such by-products had in part declined so that there was less temptation to utilize fish for that purpose specially. Competition within the state. The three canning districts of Monterey, San Pedro and San Diego have to a certain extent competed with each other in the past, and the history of this is interesting, although only brief analysis of this can be inade. There existed, previous to the war demand, two successful sardine canneries at Monterey, packing the larger sized sardines so readily obtained there. But the single sardine cannery in the south after intermittent operations finally turned exclusively to tuna packing. The seemingly superior vitality and success during the prewar period of the Monterey packers may have been due in part to the greater ease of fishing in Monterey Bay, with the resultant cheapness yet excellent condition of the supply of raw fish, and the use of a larger, more economical type of pack than the quarter-pound square cans of the imported brands. It is said that the larger type of pack finds its principal market in such countries as Cuba and the Philippines, as well as the United States. How far foreign sardines are able to com- pete for this market we have not ascertained. But it may w'ell be that an essential element in tlie history of the southern and northern packers has been the greater reliance of the former upon goods fitted for export and for competition with foreign brands. The following table illustrates the differing styles of pack made in northern and southern California, due to the larger fish which prevail at Monterey. It is said tliat occasionally there is a year when sizes of fish suitable for c{uarter-oil packs are present at IMonterey in numbers sufficient to render them easily caught, but that does not seem to be often enough to establish a quarter-oil pack there: Sardine Pack in Three Statistical Districts, According to Percentage Packed In Various Sized Cans.

Whether this will explain the greater steadiness of the price, as shown for Booth's sardines (Monterey) in Figure 60, and of the quantity packed as shown in Figure 62, we do not venture to express a decided opinion.

(Note that pack of San Diego sardines is largely the valuable smaller sizes, and of Monterey of larger sizes.) (Figure 62 shows the relative amounts packed in the three principal sardine districts of California.) This characteristic of the Monterey pack was shown also in 1915. At all events it would seem that the problem of maintaining the sardine industry in competition with for- eign and Maine sardines more largely concerns the southern packers than the northern.* It will be seen that we have not considered in detail the effect of the Maine sardine pack, as we have not yet material which bears upon the matter. But that the competition from Maine may be serious is easily ascertained from the figures for past production, in so far as we have them. In Figure 56, we have shown the pack value of Maine sardines as isolated circles for those years for which data are available. Nor have we dealt with the appearance of the sardine, or rather the adult called a pilchard, in British Columbia. The salmon canneries there packed in 1917 a total of $11,810 worth, in 1918, $413,853, and in 1919, $371,871. These were sold as pilchards, according to the ♦Note. — In so far as foreign competition Is concerned, southern canners have recently expressed considerable concern over the effect of the rate of exchange upon the selling price of Norwegian sardines in this country. As has been said by an official of a San Pedro corporation, with all foreign exchange at a low level, tlie tariff on canned fish no longer gives any protection, and Norwegian sardines are being sold to jobbers at $9.75 a case. Pacific Coast canners are compelled to ask $12 a case to pack. The Norwegian canner gets in his own money what is under normal conditions the equivalent of $20.20 for this $9.75. This is, of course an aftermath which might have been expected from the changes in the rate of exchange, and tlie low level maintained by the disturbed conditions of Europe. It Is one of those evidences of the desirability of restoring conditions in central Europe which are coming to light in increasing numbers.' 206 CALIFORNIA FISH AND GAME English style of terminology. It yet remains to be seen whether the run was sporadic or not. And, finally, we may add that it has not been our intention to in any way indicate an opinion of the future, for there is little of posi- tive value in prophesying. Yet one may surmise that the increase of population in this country would of itself greatly enlarge the markets. From 1900 to 1910 the inhaliitants of the United States increased about 21 per cent, while from 1910 to 1920 the increa.se was about 14 per cent. Yet the consumption of sardines, including the "fish packed in oil" and imported, increased over 40 per cent from 1900 to 1910, taking value as a criterion. The emphasis during the war upon the eating of fish could not help but have benefited the sardine industries. And added to these favorable facts, one may bear in mind the depletion in part of the salmon fisheries, and the general high cost of other foods. Indeed, despite the distinct evidence that war conditions had much to do with the birth of our sardine industry an optimist might find much to comfort him. CALIFORNIA FISH AND GAME 207 FERTILIZER, STOCKFOOD AI^D OIL FROM SARDINE OFFAL.* By W. L. SCOFIELD. Introductory. Although the fishins: industry in California is new and by no means fully developed it is duplicating the experience of older industries and is giving- more attention to the development of by-products. Of the liundreds of tons of fish caught in California each year, less than three quarters can be used for human food because over 25 per cent of the weight of fish is inedible. In our leading fishery industry, the canning of sardines, about 50 per cent of the catch goes into cans and roughly 50 per cent of the original weight is discarded as heads, entrails and broken and under sized fish. In mild curing king salmon, about one third of the original weiglit is lost in head, intestines, and backbone. In the past this great quantity of inedible fish material was thrown away as a complete loss. First in Europe and later in America this discarded material was found to be valuable and its conversion into a usable form proved to be financially profitable. A California sardine packer states that the profit derived from utilizing his sardine offal is sufficient to pay the running expenses of his cannery so that the return from the canning plant is "velvet." Although this case may be exceptional it indicates that the by-products of the industry have already 'assumed great importance and there is every indication that more and more fish waste will be utilized. There are at present several firms in California that make the utilization of waste fish their only business. A much larger number of reduction plants are operated in connection with fish canneries so that at present California stands well toward the top in the utilization of fish waste. The inedible or waste portion of the fish is now being converted into forms that indi- rectly serve as human food. Waste fish is reduced to fish meal which serves as food for animals and plants that are used as food by man. In other words we are now eating, directly or indirectly, nearer 100 per cent of the sardine than the former 50 per cent. The discrepancy in this 100 per cent consumption as human food lies in the fact that fish oil, a by-product of fish meal, is used for commercial purposes other than food. The edible oil refined from fish oil has as yet proven unsatisfactory although there is constant experimenting at present and a palatable salad oil maj^ result. Uses of fish meal and oil. Fish wa.ste was first dried and ground into fisli meal to be used as a fertilizer for plants and its value as fertilizer has long been recog- nized. There w^as in the past a prejudice against using the meal for stock food because the oil in the meal was said to impart a fishy flavor to the flesh of the animal eating the meal. This has been over- come by extracting the oil from the meal before feeding it to stock. In fact the oil has been found to be so valuable that the cost of extract- ing it is unimportant compared with its sale value. Fish meal, by experiment and tests on a large commercial scale, has been found to be ♦California State Fislieries Laboratory, No. 32. 3 — 14002 208 CALIFORNIA FISH AND GAME exceedingly valuable as a stock food, eciualing and exceeding tankage and grains as an animal food. Fish meal is now in demand as a food for swine and cattle but the largast demand is as a chicken food. Chicken raisers claim that fish meal has been found to be far superior to any other meaty food, as meat scraps or blood. Its value lies in its high percentage of protein, or more properly speaking, in its high nitrogen content in thg form of ammonia and in phosphoric acid as bone phosphate. These are also the elements so much valued in fertili- zers and fish meal now competes with the high grade nitrogen materials (as ammonium sulphate) and the cheap bone phosphates in commercial fertilizers. The chief demand in this state for the meal as a fertilizer comes from the fruit growers, especially the orange growers. The meal therefore has two chief uses, as stock food and as fertilizer. So far, the high price of the meal has largely confined its use to the more intensive growing of oranges and chickens and most of the sales are made to orchardists of southern California and to the Petaluma chicken raisers. Meal sold in the open market brings about the same price when sold either for fertilizer or for chicken food. Sardine oil (as well as other fish oils) is used extensively in the leather tanning industry but the chief use of the clear oil is in the making of paint and the heavier fatty materials are used in tlie manu- facture of soap. Reduction process in general. Fish contain a high percentage of oily fat, varying from 5 to 20 per cent in fresh sardines. This oil is not only valuable for other uses but it is a detriment in a stock food or fertilizer. The oil and fat are therefore extracted before the fish material is marketed as a fish meal. There are two general methods of removing oils from either vegetable or animal material. When the oil is to be used for human food it is usually pressed out. Oil to be used for commercial purposes other than as human food, is frequently removed by the use of a volatile solvent which takes up the oil. The solvent may then be volatilized and the oil recovered. The first fish reduction plants used the pressing method and this principle is still the one commonly used in the fish reduction plants of California. At present there are in the state but two plants using the volatile solvent method of extracting fish oil. This method will be described later. The usual practice (press method) is to cook the fish material sufficiently to loosen the flesh from the bones and break up the fish skeleton. The oil is then pressed out and later refined. The meal is then dried, cooled, and run through a grinder to break up bony particles. The meal is then sacked ready for shipment. There are minor variations in the appli- cation of the press method but the chief differences between plants are in the method of drying the meal rather than in the manner of pressing out the oil. One of the variations in method of drying will be described later. In order to give a more consecutive idea of the different steps in the reduction of fish to meal, it will be helpful to consider a description of a typical plant using the common press method for sardine offal. CALIFORNIA PISH AND GAME 209 A typical plant of the press type. The plant selected for desei-iption as a typical fish reduction plant, is one operated in conjunction with a Monterey sardine cannery. The reduction plant normally receives 30 tons of sardine offal per day, although it is capable of handling much larger amounts if operated continuously through the day. The fish material is almost entirely sardine offal from the cutting tables of the cannery with the broken and under sized whole fish that naturally result from canning opera- tions. The offal from the cannery is collected in a large storage bin from which a belt and bucket conveyor transports it to the top floor of the reduction plant building. The offal is about 45 minutes in passing through the plant from this storage bin to the drying floor as finished meal, but only a small amount may be run through at a time. Therefore the belt conveyor from the bin has small buckets that feed in only the proper amount of offal. Cooker. The older plants of Europe used to cook the fish in vats over a wood or coal fire but steam cooking is the common method now used in Cali- fornia. The cooking is done in a steam chamber or stationary hori- zontal cylinder roughly two and a half feet in diameter by 18 feet long and insulated with asbestos packing to conserve the heat. Offal is carried through this steam chamber at a uniform speed by means of a revolving auger action conveyor shaft whose revolutions are so timed that the fish remains in the chamber about 15 minutes. This revolving conveyor carries the cooked fish to the press. Press. The common form of press used in this state is a horizontal contin- uous screw press said to be a modification of the French olive press. The press is an auger shaped screw working into a metal jacket which is perforated with openings about the size of a pin hole to allow the water and oil to escape. The screw press is about seven feet long. The first three feet of the press casing or jacket is of lighter construc- tion, with relatively larger holes for the purpose of draining off the free water. In the last four feet, or press proper, there is another screw revolving more slowly, and the distance between the auger flanges is reduced so that the material moves forward more slowly. This slowly revolving screw works against a deeply beveled stationary disk which blocks the forward progress of the material and allows it to escape very slowly in the form of a coarse paste scraped from the beveled edges of the disk. The escaping oil and water are caught in a drip pan and piped to tanks. Dryer. The pressed material, now in the form of a paste-like mass, must be dried to prevent moulding and souring. Drying is done by hot air. In this particular plant the drying is done by passing the fish through two horizontal stationary drums or cylindrical chambers each 30 feet long. A circulation of hot air from the furnace is forced through these drums or ' ' dryers ' ' by means of a rotary blower. A vent up the smokestack, provided with rotary section fan, carries off the moist air. 210 CALIFORNIA FISH AND GAME TIk' listi paste drops froiii the end ol' the press into an auj^er conveyor and is carried through the first dryer. It then drojis to the second reversed conveyor and pa&ses hack tlirouyh the second diinn. which is situated directly luider the first. Tlie material is now in tlie form of a somewhat moist, steaming' liot meal. From the end of the dryer the meal enters a piped cold air blast which serves primarily in cooling tlie meal, hut also transports it to the grinder. Tlie ])i'ess and the dryer break up the fish very thoroughly so that very little grinding is neces- sary except for occasional bones. The meal i)asses through a small motor driven grinder and drops on the floor where it is spread out for two or three days to complete the cooling process and to dry out more completely. It is usually shoveled over two or three times on the floor befoi'e being sacked in 90-pouiid sacks for shipment. Oil recovery. The oil and water which drain from the press are sei)arated by gravity. The drippings from the i)ress are run through a series of five settling tanks. In the first tank the water and refuse particles are allowed to settle to the bottom and are drained off into the ocean. The oil is syphoned over into the next tank in the series where the gravity separation of the fat from the oil is begun. The top or first oil in the last settling tank is a fairly clear oil but the complete clarifying of the oil by settling out the fat may require several weeks and is unneces- sary. The clear oil from the top of the last tank has been used suc- cessfully as a paint oil without furtlier refining or the use of a drier in the paint, but this is not the usual practice. The oil is shipped in barrels to paint factories where it is processed for use in paints. This fish oil sells for about one-third the price of lins(^ed oil. I^elow the clear oil in the tanks is found the cloudy fatty oils and thick fat material called stearine. The heavier stearine is called ''foots." The stearine is sold for use in the manufacture of soap. As stearine contains from 40 per cent to 50 per cent oil it is sometimes heated and more oil drawn off but it usually goes direct to the soap manufacturer. A modification of the press type. In the typical plant already descril)ed, Ihc fish malcrial, after cook- ing and pressing, was dried by l)eing carried through stationary drums through which was forced a circulation of hot air from the furnace, by means of rotary blowers. We will consider briefly a plant in which a very different form of dryer is used. In this case the dryer is a revolving drum without a conveyor through the center. A cylindrical drum (five and a half feet in diameter and forty feel long) is placed on a slight decline from the press (pitch of one-half inch to the foot). The hot air is provided by a blast of burning mixture of oil and steam in a firebox so arranged that the flame blast strikes a lattice work of brick allowing only the heated air to enter the drum. A direct flame is not introduced into the drum for fear of scorching the fish. At the ojjposite end of the drum the necessary air suction- is provided by a tall smokestack (four feet in diametei- and GO feet high). On the sides of the drum are a few longitudinal cleats or "channel irons" which serve to tumble the fish material as the drum is rotated. The strong CALIFORNIA FISH AND GAME 211 draught of air and the pitch of the drum from the horizontal, serve to carry the tish waste forward as it dries out. The heavier particles of the dried material tumble out of the back end of the dryer and are caught and conveyed away by a large cold air suction pipe. There are about 200 feet of this air pipe with two rotary blowers so that the material is not only cooled, but is further l)roken up into fine meal. To prevent the lighter particles from passing up the smokestack, there is a series of three catching, or dust chambers, the operation of which will be described later when considering the volatile solvent method. The meal from the cooling pi})es is spread on the floor for several hours for further cooling and is then sacked without grinding. The pressing and tumbling in the dryer and conveyor pipes reduce the material to a tine meal containing only a few bones that have not been completely broken up. In this form the meal is ready for use as fertilizer but it should be ground before used as a chicken food. Anchovies difficult to press. It frequently happens that a sardine catch contains a large per- centage of anchovies, especially when small sardines are being taken. This is an important consideration because the ordinary screw press will not operate properly with a high percentage of anchovies, especially when the anchovies have been more than eight or ten hours out of water. The soft anchovies churn up in the press as a jelly-like mass that will not feed out and clogs the oil holes and the screw of the press. Anchovies may be used when mixed with sardine offal to lend more body to the material and thus pass it through the press. It is claimed that a mixture of half anchovies and half sardine offal will press fairly well but a lower percentage of anchovies is preferable. Yield in meal by press method. ■ The solid tiesh of the whole fish yields more meal than a like weight of offal, so that the percentage of whole fish in the offal effects the amount of meal recovered. The degree of fatness of the fish also affects the yield of meal since there is relatively more oil in a ton of offal from fat fish, but there is far less variation in the amount of meal than in the amount of oil recovered. In the typical plant already described the number of tons of sardine off'al necessary to make one ton of fish meal varies from five and a half to seven and a half, with six tons as the probable average. The weight of the recovered meal is roughly estimated at one-sixth that of the offal in this plant. Other plants with somewhat ditt'erent methods estimate the meal at one-fifth to one- fourth the weight of the offal. The remaining five-sixths of the weight is partially recovered as oil and stearine but most of it is water of which the greater per cent is driven off by evaporation. The water content of fresh sardines is high (probably 60 to 75 per cent) and canned sardines are about 60 per cent water but a low moisture content is desirable in both fish meal and oil. The meal contains less than 10 per cent moisture and the oil less than 2 per cent water. Composition of meal by press method. Fish meal sells on its chemical composition and frerjuent samples are subjected to chemical analysis. The chief value of fish meal lies 212 CALIFORNIA FISH AND GAME in its nitrogen and phosphoric acid content. The iiitrogen as ammonia is the most important element and the price of a fish meal on the open market is largely determined by the percentage of ammonia present. The ammonia content varies between 8 and 14 per cent, but a high grade meal usually has between 10 and 12 per cent ammonia. The phosphoric acid content as bone phosphate is the next most important consideration in fixing the price. A low moisture content is desirable as the bu3^cr does not care to pay for useless weight in water. The water content is not run below 6 or 8 per cent, not only because of the cost of further reducing the per cent, but also because the sacked meal w'ill absorb sufficient moisture from the atmosphere to bring it up to 6 or 8 per cent. The moisture content of meal varies from 8 to 13 per cent but is usually about 10 per cent. The pressing method does not extract all of the fish oil from the offal and the resulting meal from this process contains from 7 to 10 per cent of oil (ether extract). The chemist's analysis of the meal produced by the typical plant we have considered gives the following results expressed roughly: Nitrogen 9 to 10 per cent Phosphoric acid 5 to 10 per cent Nitrogen as a-Jiimonia 10 to 14 per cent Phosphoric acid as bone phosphate 10 to 22 per cent Moisture 9 to 12 per cent Oil (ether extract) 8 to 10 per cent The term protein is often used in the analyses of meal to include the proteids or nitrogenous matter of the soft tissues of the fish body. Such classifications divide fish meal into protein, oil or fat (ether extract), Avater and mineral ash. In such cases the protein content ranges from 50 to GO per cent, a much greater percentage than in fresh fish with its higher moisture content. A rough rule of thumb some- times followed when the nitrogen content of the meal is given, is to multiply the percent of nitrogen by 5.25 to give the protein content. In judging a fish meal it is essential to know the percentage of (1) ammonia, (2) phosphoric acid, (3) moisture, and (4) oil (given in the order of their importance). Yield of oil by press method. In sardines there is a great deal of oil in the flesh just back of the head but the fat about the entrails and the liver itself ' is. especially rich in oil. In cutting sardines for canning, the fish is cut in two near the back of the body cavity and only the posterior half of the fish is canned. Thus the head and entrails are discarded as offal. There- fore a ton of offal w-ill yield more oil than a ton of whole fish and the per cent of whole fish in the material will aft'eet the yield of oil. The greatest source of variation is the periodic fluctuations in the fat content of the sardines themselves. At some seasons of the year they are very fat with a high oil content, while at other seasons, especially in the spring, the fish are thin and liave relatively little fat and oil in their bodies. The fat content of sardines varies roughly from 5 to 20 per cent. As anchovies have much less oil than sardines a quantity of anchovies mixed in the offal reduces the oil CALIFORNIA PISH AND GAME 213 yield per ton of material. For the above mentioned reasons the yield of oil varies greatly from day to day and from month to month. In the typical plant we are considering, the oil yield varies from 7 to 27 gallons per ton of offal, with a rough average yield of 10 to 12' gallons of oil and fatty mriterial (steariiie) per ton of offal. Composition of oil by press method. Pish oil, like fish meal, sells on its chemical analysis. The oil with a small per cent of free fatty acids or unusable material is the high- grade oil bringing the best price. The impurities are referred to in the trade as free fatty acids and M. I. U. The M. is moisture and other volatile matter, the I. is insoluble impurities and the U. is unusable or unsaponifiable matter. The amount of impurities in an oil varies naturally with the method and care used in the refining or settling process. As more care is now being given to this phase of the subject, some of the west coast oils are finding ready sale locally and in the Eastern States. In the past the lack of care in refining and looseness in grading the oil has caused much of the west coast oil to be classed as inferior grade and accepted at a poor price by eastern buyers. For years the Newfoundland and American cod oils Avere the favorites till salmon oil was found to be equally good. The whale oil business, having been so long established, now has definitely established grades. The sardine oil, being new from this coast, has not yet come fully into its own. The use to which the oil is to be put largely determines the purity of oil necessary. A leading dealer in fish oils makes the general statement that fish oil for use in paints should not have over 5 per cent free fatty acids and not over 2 per cent M. I. U. For tanning purposes the oil should be from 5 to 7 per cent acids and 1 per cent M. I. U., but clear settled (tanked) oil for use in the better grades of soap should not exceed 3 per cent acids and 2 per cent M. I. U. For a No. 1 grade of sardine oil the limit of impurities is usually set at 2 per cent free fatty acids and 2 per cent M. I. U. The press method, with proper care in operating the settling tanks, yields a sardine oil low in acid content and well within the limit as to other impurities. The chemical analyses of the sardine oil produced by such a plant show the following results : Free fatty acids .5 to 1.5 per cent Moisture and volatile matter .1 to .7 percent Insoluble impurities a trace to .03 per cent Unsaponifiable matter .2 to .9 percent Volatile solvent method. In this method there is no press, the oil being recovered by the use of gasoline as a volatile solvent. The elimination of the press permits of the reduction to meal of almost any kind of fish material Avithout readjustment of machinery or extra labor. Fish scraps, trimmings from the fish and abalone markets, offal, meat scraps, whole fish, sharks, squid and anchovies are reduced with equal facility. In the two Cali- fornia plants there is no separate cooking cylinder, but the cooking and drying are combined in one rnachine. In the press method the oil and water are pressed out and the material then dried. In the gasoline process the material is dried to eliminate the water and later the oil is 21-1 CALIFORNIA FISH AND GAME extracted fiom llic dried iiiciil. Tlie two gasoline plants of this state are not eon)ieeted with a fish catmory, ])ut are operated as an inde- pendent l)usiness. piirrhasinor the i-aw iiialerial from other firms. One plant nses mostly iisli scraps and the other, located in one of the sardine canning centers, operates on sardine offal purchased from the canneries. A brief description of the latter plant will better illustrate the method. This plant has a capacity of abont 35 tons of offal per day when employing five or six men. With seven or eight workmen the capacity can be increased to 50 or 60 tons per day. The sardine off'al is trans- ported to the plant by anto truck and dumped into a storage bin from which a belt cenveyor with small buckets carries the material tn tlie dryer. The conveyor is filled by hand so tliat the amount fed in may be varied according to the directions given by the man operating the dryer. Dryer. The dryer (cooker and dryer combined) is a large revolving hori- zontal cylinder, 40 feet long and 4 feet in diameter, operating on the same general principle as the dryer described above, under "IModification of the Press Type of Plant" which merely dried the cooked and pressed material. This dryer first cooks and then dries the fresh offal from the storage bin. The heat is provided by a burning spray blast of mixed steam and oil, the draught being created by a tall stack. In this case the flame is shot directly into the dryer. The conveyor empties the offal directly into this flame and the four or five longitudi- nal cleats of the revolving dryer keep it tumbling. The amount of flame and heat may be delicately regulated by adjusting tlie amount of oil and steam sprayed in. When fairly dry material is being received, the flames extend only two or three feet into the cylinder, but with particularly wet material the flames may be shot into the dryer a distance of eight or ten feet. The wet offal is tumbled in the flame during several revolutions of the cylinder till the material is sufficiently heated to cook the flesh free from the bones. As the moisture is absorbed by the hot air blast and the flames, the dried (ish material, being liiihter in weight, is blown toward the l)ack end of the dryer. The cylinder is set up with only a vei-y sliizht ])i1ch downward, the draught being sufficient to carry the flsli through. The fish I'cmains in the dryer about thirty minutes from the time of entering the flames till it is blown to the back end of the cylinder as dry meal. The offal is not oid\- cooked and dried in the cylinder, but the tumbling of the dried material breaks it up into a coarse nu^al, the chunks of whieh are usually no larger than a pea. In this drying process it is essential that the sui)ply of material being fed into the dryer be uniform, in order to reduce as nuieh as possible the readjusting of the flame. When a great amount of wet fish is fed in rapidly, the drying is not comjilete and the product is too moist. If the supply of raw material is reduced suddenly, or is much dryer than the preceding supply, the excessive heat burns the fish into hard cakes and extracts free oil, whi'-h collects in the bottom of the cyliiuler and sometimes catches on fire. Recovery of meal from dryer. As the back end of the cylinder is open, the meal is blown out \n\o a small catching passage Avay which has a small hole in the floor to CALIFORNIA FISH AND GAME 215 allow the heavier particles of the meal to escape, but much of the meal is in the form of dust and is carried past this opening by the air current. In order to recover this dust, the air current is led through three dust chambers before it escapes up the stack. The opening into the first chamber is near the top and the outlet near the floor, so that the heavier dust settles to the floor. In the second dust chamber the intake is near the floor and the outlet near the top, so that the finer dust settles in this second chamber. The air current then drops again in a third chamber before escaping up the stack, so that all but a negligible amount of very fine dust is recovered. The dust chambers are emptied once or twice a day by opening a door in the side wall and shoveling up the accumulated fine meal. The dried meal is known as ' ' unfinished stuff, " as it has yet to be processed to remove the oil. This unfinished stuff is spread on the concrete floor to cool before it is ele- vated to the second story of the building in readiness for the next step in the process, the extraction of the oil. Extraction tank. The extraction tank is a heavy cylindrical steel tank about nine feet in diameter and al)out fourteen feet high. The tank is filled through a door in the top to within eighteen inches of the top with the dry unfinished meal. Gasoline is then sprayed in from the top through a perforated pipe till the tank is filled with gasoline sufficient to cover the meal. The tank full of meal and gasoline is then heated l)y intro- ducing steam at the top of the tank. The heat is said to be about 325 degrees and is continuous for an average of about eight hours. The gasoline begins to take up the oil of the fish meal even before the meal is thoroughly heated, so that the process of draining off the mixed gasoline and oil is begun soon after the steam is introduced. The bottom of the tank is a sheet of steel perforated to allow liquid to drain through it. Under this metal sheet there are alternating layers of charcoal and gunny sacking to catch and hold particles of meal, so that the liquid may be drained off as pure as possil^le. After this oily gasoline is drained out, the tank is again flushed Avith a fresh supply of gasoline, which is also drained oft'. A small door in the side of the tank, even with the metal floor, is then opened and the meal pulled out. Screening. The meal that has been removed from the extraction tank is then screened or sifted to remove any of the larger particles that have not been broken up by the process so far. The sifted meal is then ready for sacking. The screenings or tailings consist of pieces of backbone, bones of the skull, especially the cheek plates or opercles, small hard lumps formed by a portion of the intestine, and a few chunks of meal that remain packed or were burned somewhat in the dryer. These tailings may be ground up and resifted, or, as is frequently done, may be run through the dryer again, which breaks up most of the chunks and saves grinding so much material. The tailings, after being ground up into fine particles, are mixed with the sifted meal and sacked. It is essential that the meal be quite dry before sacking. If there is much moisture, the meal will mould and heat in tlie sack. In case the final meal is found to be too moist, it is run through the dryer again before 4 — 14002 216 CALIFORNIA FISH AND GAME sacking. Tlie sacked meal should not have much over 10 per cent moisture. Recovery of oil. The liquid drained from the extraction tank is carried by pipe into a smaller tank called the evaporating tank, which is about 12 feet long and 5 feet in diameter. It is provided with a large steam coil capa])le of heating the liquid to 300 or 325 degrees. The heat volatilizes the gasoline and a pipe at the top of the tank carries off the gas thus formed. After about four hours practically all the gasoline is driven off, leaving only the fish oil remaining in the tank. If much gasoline is left in the oil and the oil is later refined, a serious explosion is apt to result, so that it is essential to drive off all the gasoline possible. The oil is then blown out of the tank by steam pressure and conducted by pipe to a storage tank. The oil is later deodorized by heating to about 600 degrees, which also removes practically all of the moisture and other volatile impurities. The oil is then ready for shipment to the paint manufacturer. Recovery of gasoline. The volatilized gasoline escapes from the evaporating tank in a pipe that is run through a condenser or coiled pi]ie in a bath of running cold water. Ocean water is particularly good for cooling the condenser pipe. The condensed gasoline drains into a storage tank and is read}' for use again in the extraction tank. This distilled gasoline is referred to as "high power gas" because of its greater strength in taking up fish oil in the extraction tank. The high power gas has been freed from many impurities and is much more volatile than ordinary commercial gasoline. In fact the commercial gasoline is usually run through the evaporating process to refine it before it is used in the extraction tank. Composition of meal. The meal resulting from the gasoline ni(>thod has practically the same moisture, phosphoric acid, bone phosphate, nitrogen and ammonia con- tent as in the press method. The meal has about 10 per cent each of nitrogen and moisture. The phosphoric acid content is 7 to 8 per cent and the bone phosphate is in the neighborhood of 16 per cent, although quite variable. The ammonia content is 8 to 12 per cent. The chief difference in the two meals is in the oil content. The volatile solvent method removes more of the oil than the press. The final meal by the gasoline method has about 3 per cent of oil as contrasted with 8 to 10 per cent of oil by the press method. Therefore the oil yield per ton of offal is higher by this method than by the press method, the yield being about 20 gallons per ton of offal. The yield of meal is said to be about 23 per cent of the weight of the offal. This yield is as good or better than the percentage of meal recovered from pressing. Practi- cally all of the meal from this plant is sold for chicken food and is shipped to Petaluma. Quality of oil by gasoline method. By the gasoline extraction process the resulting oil, although rela- tively of greater quantity, is not the high quality oil obtained by methods of pressing. When the fish first enters the dryer and is tum- CALIFORNIA FISH AND GAME 217 bled in the flame blast, the oil in the fish is sufficiently scorched so that the resulting oil is black or dark brown, and up to the present time has not been refined to a clear oil. For this reason its use is almost entirely confined to the manufacture of paints, where its color is no drawback except that it is unfit for use in white paint. This dark oil seems to give good satisfaction in colored paints, other than white, even in cream colored paint. The recovered oil has very little of the heavy fatty materials as foots or stearine. So little saponifiable material is recovered that it does not, at present, pay to separate it for sale to the soap manufacturers. The following are a few of the many bulletins published by the U. S.

It is a fixed purpose of the California Fish and Game Commission to maintain a system of fishery statistics so complete and so continnons that the varied and changing conditions of the fishing industry may be compared year by year in order to determine its actual condition and future prospects. As a partial supplement to the statistical records ot the catch, collected and compiled according to law, these notes on methods and practices are prepared to aid the investigator in future years to reconstruct in his mind the actual conditions in 1921, enabling him to understand and interpret the figures of the catch. LOCAL CONDITIONS AND GEAR. Local conditions have their natural effects upon methods and gear, producing in southern California an industry unique in many ways. The sardine fishery is not an independent industry, for the fisherman engaging in it spends fully half of the year fishing for albacore, tuna, sea bass, mackerel, halibut, or rock cod, and hence his boat and gear are modified to meet the requirements of these other fisheries. By far the greater number of boats fishing sardines are typical albacore boats which are converted for use during the winter sardine season by the removal of bait-boxes and poles. Many, however, of a different type, were built before the albacore fishery became so profitable, and are used, during the off season for sardines, in fishing with trammel nets for halibut, or with set lines for rock cod. These two distinct types of boats are manned, respectively, by the two nationalities which dominate the fishery, the Japanese and the Italians. Weather conditions also have influenced the type of boats used. Although the boats are perfectly seaworthy and capable of traveling several hundred miles, the uniform character of winds and absence of sudden storms has permitted the development of a type of fishing boat poorly adapted to a short choppy sea, being long and narrow and having a wedge-shaped bow with little flare. THE LOCATION OF THE FISHERY. The California sardine, Sardina caerulea (Girard), occurs in con- siderable abundance along the entire west coast of the United States, including Alaska aiid British Columbia, and southward on the coast of Lower California, but the chief centers of the fishery are Monterey, San Pedro, and San Diego. In southern California sardine canneries are located at San Pedro, Wilmington, Long Beach, Newport Beach, and San Diego, the areas fished covering a radius of fifty miles or so from these points. In the San Pedro district, deep water fishing oft' a rocky coast is found from Point Firmin north to Redondo and off sandy beaches from Point Firmin south to Newport. At San Diego similar conditions are found to the north, about La Jolla, or from Point Loma south to the Mexican border. The winter sardine fishery is chiefly in ♦California State Fisheries Laboratory, Contribution No. 33, 220 CALIFORNIA FISH AND GAME deep water two to ten miles from shore, but iu tlie suniiiicr, lish are caught inshore near the sandy beaches. FISHING SEASON. The sardine canning industry, which utilizes practically the entire catcli in the San Pedro district, depends a great deal upon the large fish 20 to 30 centimeters long, known as "pound-oval" size, from the cans in Avhieh they are packed. The fish approach the coast in Der^om- ber and are taken in great quantities until April or May, when smaller sizes become relatively more numerous, but canning sometimes starts early in November, utilizing the smaller sizes of sardines known to the trade as "quarter-oils." (Fig. 64.) The same sizes are taken at San Diego, but a larger proportion of the pack consists of the smaller fish, and the season is therefore somewhat extended.

The 1920 sardine season at San Pedro as shown by the Com- mission's reports of amounts of sardines received weekly at the canneries. A summer sardine fishery, scarcely less important economically than the winter fishery, although yielding no .statistical record and having no money value, is pursued from Santa Barbara to San Diego. It is the bait fishery, an essential factor in the summer albacore industry. Small sardines of "quarter-oil" size or smaller are highly prized by the albacore fishermen as live bait, and one-half to three-quarters of a ton per boat are taken in the morning whenever possible off sandy beaches before proceeding to the albacore fishing grounds. It is true that anchovies serve as a substitute, but they are not as desirable nor as much sought after as are the small .sardines. This bait fishery con- tinues throughout the albacore sea.son, i. e., from June to October. Modified sardine nets called "bait nets" are used and will be describiMl iatrr. Boats. TYPES OF GEAR. As mentioned above, there are two chief types of boats employed in the sardine fishery : one operated by the Italians and the other by the Japanese. Americans (native born), Scandinavians, and Austrians also CALIFORNIA PISH AND GAME 221 engage in sardine fishing, but only in small numbers,* and they use boats which may be classed Avith one or the other chief types. The Italians were probably the first sardine fishermen on the coast to use the present style of round-haul nets, and introduced their methods and gear from Italy. Their boats reflect an adaptation to trammel-net or set-line fishing after the sardine season, being smaller than the Japanese boats and having less power and speed. A typical Italian sardine boat (Figures 65 and 66), carrying a crew of five or six men, is 35 feet long, of 10- foot beam, and 4-foot draft, with a wedge bow and fantail stern. A 20-foot mast is stepped in near the Fig. 65. A typical Italian sardine boat.

The space below is occupied by a two- or three-cylinder distillate engine of 20 to 30 horsepower and sleeping quarters for four.

The operator stands in the open cabin hatchway amidship. his hands on a small steering wheel inside the ca))in and his IVet oi)eratin,u- tlic controls ot" the engine. On some boats a movable box-like hood with glass windows in its sides is placed over the open hatch to protect the head and shoulders of the operator from the weather. Tlie speed of such I)oats is from six to eiyht mih's per hour and tliey are i-elatively economical in oi)eration. Tlieir small size, however, reduces the capacity and their speed limits the radius of operation in the sardine fishery. It also unfits them for the more sti'cnuous duty of catching: albacore. The Japanese type of sardine boat is a modification of the earlier market fishing boat and is built primarily for the catching of albacore. It is longer, speedier, and more powerful than the Italian boats, and more comfort is provided for the operator by building an enclosed pilot house amidship. It is thus adapted to traveling greater distances in search of schools and returning with the catch in less time.

A typical Japanese sardine boat (Figures 66 and 73), carrying a crew of seven or eight men, is 45 to 50 feet Ions:, of 12-foot beam, 5-foot draft, and powered with a three-cylinder distillate or crude-oil engine of 40 horsepower, which drives the boat at a speed of from 9 to 12 miles per hour. The vertical bow is wedge-shaped and the stern of fantail type, but broad and rather square. A low trunk cabin with a hatchway on the side runs from near the bow to the pilot house amidship, which is placed directly over the engine. The controls are arranged in the pilot house so that one man operates the boat. The forward cabin is small, having lumk space for two or three men, but extra bunks are fitted in the hold beneath the afterdeck and may be reached through a raised hatch just aft of the cowl or extended roof of the pilot house. A take-down mast set at the forward end of the cabin is carried in a horizontal position, one end resting on the ])ilot house. The catch of fish is pilerl all over the afterdeck and along the sides of the cabin as far forward as necessary, and is confined by side- boards which may be built up on the gunwales three or four feet high, according to the size of the load. A space about six feet wide and runninar athwartship is reserved in the stern of the boat for piling the net and for standing when paying it out or hauling it in again. The CALIFORNIA FISH AND GAMfi 223 fish are kept out of this area by a low transverse bulkhead or partition which may be built up in the same way as are the sideboards. In the center of this l)ulkhead is erected a standard bearing an electric light on a swinging arm to light the deck for night hauling. This is the newer type of boat representing three-fourths of the fishing craft in southern California, and is now being built for fisher- men of all nationalities, Japanese and Italians alike, for use in the albacore and sardine industry.

Data from boat registration records. Nets. Sardines are caught entirely in huge nets laid out in circles and hence called "round-haul" nets. Italian and Japanese nets are alike in principle and general plan, but differ in details of design as com- pletely as do the types of boats (Figure 67). Any round-haul net is made in three sections ; a right wing, a left wing, and a bunt or bag. The wings are long strips of large meshed net attached at each side of the bunt and are used to encircle the fish and drive them into the bag. The bag is the sacklike center portion of the net, made of fine meshed webbing and used to hold the fish until they may be landed on the boat. The webbing of wings and bunt is fastened to a light rope called the "cork line," buoyed with numerous corks so that the whole net floats in the water with the cork line on the surface. The lower edge of the net is fastened to a similar line — the "lead line" — M^eiglited with leads at frequent intervals. These two ropes, in addition to float- ing and ballasting the net, take much of the strain of hauling and serve as reenf orcein ent for the edges of the webbing. Webbing manufactured in Japan is more popular in southern Cali- fornia for making sardine nets than the American or European product, partly, at least, on account of its lower cost. Hard-laid cotton seine twine is preferred for wings and landing sack, and cable-laid twine for the greater part of the bunt, particularly the fine mesh ; but notions of economy lead some to use the cheaper and less durable medium-laid twine in the wings. Each fisherman or boat owner builds his net after his own pattern and according to his latest ideas, producing a diversity of design whicli no doubt makes for progress in the developing of perfect gear. This great diversity make? it difficult to select a type, and when once 5— IJOO:: 224 CALIFORNIA FISH AND GAME selected it is almost impossible to chaw up specifications which could serve in building a net like the oritjiiial, for net making is an art and can be learned only by experience. Two iiets apparently of the same design will lish with different success, due to the intlividual skill of the makers expressed in the "hang" of the webbing; hence, the accompany- ing diagrams must not be considered as working drawings, but only as sketches sufficiently detailed, it is hoped, to portray the characteristic points of the types.
