Hunt Institute Archives Text Discovery Platform

Search a large and growing portion of our online collections, including handwritten documents.
PROTOTYPE

This prototype uses state-of-the-art artificial intelligence, including a vision-language model (VLM) capable of reading handwritten documents as well as typed and printed text, to create searchable transcriptions of digitized materials in the Hunt Institute Archives. This makes it possible to search the textual contents of individual pages, including material that may not be described in the archival catalog.

Use Keyword search for specific words, names, dates, scientific names, or phrases. Try Semantic search (experimental) to describe a topic, question, or kind of material when you do not know the exact wording used in the documents.

About the AI-generated transcriptions

The transcriptions are generated automatically from page images and may contain errors, especially with difficult handwriting, unusual names, multiple languages, image-quality problems, or complex layouts. They are intended primarily as a discovery aid rather than authoritative transcriptions.

Each result provides the generated transcription and links to the original digitized material and associated archival description so that readings can be checked against the source. The transcription workflow uses AI models run locally by the Hunt Institute.

About Keyword and Semantic search

Keyword search is the default and matches the wording in the transcriptions. Results contain all your terms. Use quotes for an exact phrase. Substring matching is supported, so aceae can find plant-family names ending in -aceae.

Semantic search (experimental) is useful when you know what kind of material you are looking for but do not know the words used in the documents. It ranks transcribed passages by similarity of meaning, so relevant results may not contain the exact words in your query.

Semantic queries can be broad research topics, descriptions of activities or relationships, or natural-language questions. For example:

Semantic search is not a chatbot: a question is used as a search query, and the system returns archival passages that appear conceptually related to it rather than generating an answer or summary. Short descriptions and ordinary research questions generally work better than lists of disconnected keywords. Quotation marks have no special meaning in Semantic mode. Cross-language matching may work in some cases, but it should not be treated as translation.

Keyword and Semantic search are complementary. Keyword search lets you require particular wording; Semantic search can surface differently worded passages about the same subject. Depending on the research question, trying both can reveal different useful material.

Open a result: use the prominent page-and-transcription link to see the metadata, PDF, and full transcription. Keyword-search terms are highlighted in the transcription.

Archives Collections Database (ArchivesSpace): the Collection, Item/Folder, and Digital Object links open the corresponding archival records. Collection-level dates describe the collection as a whole, not necessarily the specific item or page.

If a PDF does not load: on the detail page, use the Digital Object link, click “Go to file” in ArchivesSpace, and navigate to the page number shown here.

Current limitations
  • Automated transcriptions can contain missing or incorrect text or unintended repetition. Difficult handwriting, image quality, unusual layouts, and multiple languages can reduce accuracy. Always consult the original page image when an exact reading matters.
  • Semantic search remains experimental. Its rankings are an additional discovery aid, not a complete or definitive set of relevant results, and highly ranked pages can sometimes be only broadly related.
  • This is an active prototype. Search coverage, transcriptions, functionality, and the interface may continue to change as additional archival material is processed and the system is improved.

MANGOSTEEN—MANGROVE
781

porting seeds (they retain their viability a short time only), introduction of the tree into the western hemisphere did not take place until about 1700, when it was planted in Brazil; thence it reached the West Indies about 1740. It has taken on the appearance of a wild species in many parts of tropical America, trees springing up everywhere from seeds scattered by the roadside. During the ripening season, mangos are a major foodstuff wherever grown.

Description.—The tree is evergreen, often reaching large size (50-60 ft.) and attaining great age. It is one of the favourite shade trees of the tropics. The leaves are lanceolate, up to 12 in. long; the flowers, which are small, pinkish and fragrant, are borne in large terminal panicles. They are polygamous, i.e., some have both stamens and pistil, others stamens only. The fruit varies greatly in size and character, as would be expected of a species (or combination of species) that has been in cultivation for a long time. The smallest mangos are no larger than plums, while others may weigh four or even five pounds. The form is oval, round, heart-shaped, kidney-shaped or long and slender. Some varieties are beautifully coloured with shades of red and yellow, while others are dull green. The single large seed is flattened, the flesh that surrounds it yellow to orange in colour, juicy and of delicious spicy flavour. Fryer, writing of mangos in 1673, said "for Taste, the Nectarine, Peach and Apricot fall short." Hamilton, who wrote in 1727, went even further. "The Goa mango," he declared, "is reckoned the largest and most delicious to the taste of any in the world, and I may add, the wholesome and best tasted of any Fruit in the World." There are ample grounds for considering the mango—as has been done by many writers—the "king of tropical fruits."

Most of the seedlings so abundant throughout the tropics do not represent this fruit at its best. While of good flavour, they are commonly characterized by coarse fibres throughout the flesh, which makes eating them disagreeable. In contrast, the fine grafted varieties that have originated in India and a few other regions, as well as seedlings of the race cultivated in the Philippines and other countries (known as Mangos de Manila in Mexico and Filipinos in Cuba), are almost devoid of fibre and are of excellent quality.

Distribution and Cultivation.—In 1889 the U.S. department of agriculture introduced into Florida the first of the grafted Indian varieties known in the United States—the variety Mulgoba, of superb quality but not highly productive. In subsequent years, mainly through the efforts of the Reasoner brothers and David Fairchild (q.v.), more than 50 other choice varieties were taken to the United States, whence the cultivation of several gradually spread to many parts of the American tropics. The British and French also introduced a number into the West Indies. Some of the best imported varieties are Pairi (known in Jamaica as Bombay), Borsha and Amini. In addition to these such varieties as Carabao from the Philippines and Saigon from Cambodia should be mentioned, as well as Julie, which first received horticultural attention in the French West Indies and later became popular in Jamaica.

Because of the failure of many varieties to produce regular and heavy crops of fruit, they have been replaced in commercial orchards by Haden (a seedling of Mulgoba that originated in Flor-
