76 SUGGESTIONS FOR THE FORMATION LABELLING AND ARRANGING. I regard labels as quite unnecessary, and even objectionable, as tending to limit the space available for notes. I should recommend that a neat stamp with the following words be procured, "Essex Field Club Herbarium," with which each sheet should be carefully stamped. Under this should be neatly written :—1st, The name of the plant; 2nd, Where it was collected; 3rd, By whom collected; 4th, Date of collection, and any notes of interest relating to the geological strata, situation, &c., or calling attention to any interesting characters in the plant itself. The nomenclature and arrangement adopted should be that of the last edition of the "London Catalogue of British Plants." 1 All plants belonging to critical genera should be submitted to some well-known authority for confirmation if possible. The value of the collection will be greatly enhanced by the adoption of this plan. The following are essential features in the cabinet. It must be fitted with sliding shelves six inches apart, a little larger than the sheet of mounting paper adopted, and it must be dust-tight. In other respects the cabinet must be made to harmonise with the fittings of the museum. One question now only remains :—By what means is this work to be accomplished ? Clearly by the united efforts of all who will volunteer to assist. In order to make such voluntary work effective it would be necessary to divide the responsibility undertaken into different departments. I would suggest that the following subdivision of work would be convenient, 1st. Collecting and drying must clearly be undertaken by the same worker; but it will be probably found useful to a certain extent to subdivide this labour, to prevent waste of power by several going over the same ground. Thus, some living near the coast might give their particular attention to coast plants. Some volunteers might undertake to give their particular attention to special orders or genera of plants; for instance, one might undertake the Rubi; another the Batrachian Ranunculi ; a third might undertake to collect all the forms of Primula, while some might collect generally in their own localities. 2nd. Mounting, arranging, &c. A small committee of, say, three 1 I should say, in general, there are many points in which such a standard will be susceptible of improvement,—G. S. Boulger,
