as marketed by the plant. Such products are usually ‘final’? and 
in form for consumption; however, the products may be “interme- 
diate’ and require further processing before reaching the consumer 
markets. An outstanding example of an intermediate product is 
green-salted groundfish, which almost invariably is further processed 
before final marketing. In reviewing the statistics of manufactured 
products it should be observed that intermediate products are not 
shown where they are prepared to the final stage in the original 
plant. An exception to this rule, however, is in the case of the pro- 
duction of mild-cured salmon, which, on account of its importance, 
is shown in its entirety, whether further processed in the producing 
plant or not. In this connection it should also be stated that several 
of the byproducts for which statistics are shown may be intermediate, 
and the plants producing the final products are not surveyed by this 
Bureau. Outstanding among such products are marine-animal oils, 
scrap, and meal. 
Statistics of persons engaged in wholesale and manufacturing 
establishments are reported in three groups: Proprietors, salaried 
employees, and wage earners. 
Proprietors represent those persons who devote their time to the 
conduct of the enterprise and receive their compensation in the form 
of profits. Managers of branch houses are not classified as pro- 
prietors. s 
Salaried employees usually include those persons paid by the week 
or month, while wage earners usually consist of those paid on a per 
diem or piece-work basis. This, however, is not true in all cases, 
since the distinction between these two classes depends primarily 
on the character of the work done rather than the unit of time em- 
ployed for calculating rates of pay. In general, office employees are 
classified as salaried employees. Other emplovees, including plant 
workmen, are classed as wage earners. Plant foremen or superin- 
tendents are classified as salaried employees unless they are princi- 
pally engaged in manual labor; in which case they are classified as 
wage earners. Active officers of corporations are classified as salaried 
employees. Statistics of wage earners are shown in two forms: The 
average number employed during the operating season; and the 
average number employed during the year (the monthly average for 
the year). 
Transporting trade.—Statistics are obtained on the number of the 
crew and number of boats and vessels engaged in transporting fishery 
products from the fishing grounds to port or from port to port. How- 
ever, if a craft is engaged in catching fish at any time of the year it 
is included as a fishing craft rather than as a transporter. 
Publication of data.—Statistics of employment in the fisheries, craft 
and gear engaged, catch and value of catch, and certain data on indus- 
tries related to the fisheries are summarized and published in bulletin 
form as soon as possible after completion of each survey. Later the 
figures in more detail are included in the annual reports of the Division. 
LOCAL AND SPECIAL SURVEYS 
Landings at certain important United States ports.—Statistics of the 
lands of aquatic products at the principal New England ports (Boston 
and Gloucester, Mass., and Portland, Maine) are obtained in a
